如何绑定特定的，从 XML class 结构反序列化到 Treeview
How to bind specific, deserialized from XML class structure to Treeview
我想制作将数据从我的 xml 文件反序列化为 class 结构的应用程序。我通过 'Paste XML as classes' 工具准备了 classes，但是所有内容都是在公共字段或表上创建的，当我尝试将其更改为 List 或 ObservableCollections 时，序列化程序停止正确加载 xml 文档。
接下来我想做的是从 treeview 中选择一些元素，编辑它，然后再次保存到 xml 文件。我不想直接在 .xml 上这样做。
这是我的 XML 示例：
<plan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="schema.xsd">
<nagłówek>
<autorzy>
<nazwa>Autorzy:</nazwa>
<autor atr="one">
<numer>222</numer>
<imię>Rust</imię>
<nazwisko>Snow</nazwisko>
</autor>
<autor>
<numer>111</numer>
<imię>Ian</imię>
<nazwisko>Nower</nazwisko>
</autor>
</autorzy>
</nagłówek>
...
这里是 classes
的例子
/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public partial class plan
{
private planNagłówek nagłówekField;
private planGłówny głównyField;
/// <remarks/>
public planNagłówek nagłówek
{
get
{
return this.nagłówekField;
}
set
{
this.nagłówekField = value;
}
}
/// <remarks/>
public planGłówny główny
{
get
{
return this.głównyField;
}
set
{
this.głównyField = value;
}
}
}
/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class planNagłówek
{
private planNagłówekAutorzy autorzyField;
/// <remarks/>
public planNagłówekAutorzy autorzy
{
get
{
return this.autorzyField;
}
set
{
this.autorzyField = value;
}
}
}
以及我如何加载 xml:
// Create an instance of the XmlSerializer specifying type and namespace.
XmlSerializer serializer = new XmlSerializer(typeof(XML.plan));
// A FileStream is needed to read the XML document.
FileStream fs = new FileStream("...somepath.../Untitled4.xml", FileMode.Open);
XmlReader reader = XmlReader.Create(fs);
// Use the Deserialize method to restore the object's state.
i = (XML.plan)serializer.Deserialize(reader);
fs.Close();
这是我的 xml 文件，也许这会对你有所帮助:)

要在 WPF TreeView 中显示 class 的层次结构，在 XAML 中，您需要定义一个 HierarchicalDataTemplate corresponding to each type of class in your hierarchy that might have children, and a DataTemplate 对应于每个类型的 class 在您的层次结构中不会有 children。每个数据模板都应该定义一个框架元素（例如 TextBlock，或者一个容器控件，例如 DockPanel 和任意数量的嵌入式框架元素，如 children）来显示数据树中那种类型的 class，具有适当的绑定。
首先，auto-generate class 为您的 XML 使用 xsd.exe。要简单地在树中显示数据，您不需要实现 INotifyPropertyChanged 或对 children:
使用 ObservableCollection<T>

接下来，在 XAML 中定义一个用户界面，在其中显示这些 classes，为每个级别手动创建适当的数据模板：
<Window x:Class="WpfTreeViewNew.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:w="clr-namespace:WpfTreeViewNew"
Title="Window1" Height="300" Width="600">
<Window.Resources>
<HierarchicalDataTemplate DataType="{x:Type w:plan}" ItemsSource="{Binding Path=Items}">
<TextBlock Text="Plan">
</TextBlock>
</HierarchicalDataTemplate >
<HierarchicalDataTemplate DataType="{x:Type w:planNagłówek}" ItemsSource="{Binding Path=autorzy}">
<TextBlock Text="Nagłówek">
</TextBlock>
</HierarchicalDataTemplate >
<HierarchicalDataTemplate DataType="{x:Type w:planNagłówekAutorzy}" ItemsSource="{Binding Path=autor}">
<TextBlock Text="{Binding Path=nazwa}"/>
</HierarchicalDataTemplate >
<DataTemplate DataType="{x:Type w:planNagłówekAutorzyAutor}">
<Border BorderBrush="Gray" BorderThickness="1" MinWidth="300">
<StackPanel Orientation="Horizontal">
<TextBlock Margin="3" Text="{Binding Path=atr}"/>
<TextBlock Margin="3" Text="{Binding Path=numer}"/>
<TextBlock Margin="3" Text="{Binding Path=imię}"/>
<TextBlock Margin="3" Text="{Binding Path=nazwisko}"/>
</StackPanel>
</Border>
</DataTemplate >
</Window.Resources>
<Grid DockPanel.Dock="Bottom">
<TreeView Margin="3" Name="treeView1">
<TreeView.ItemContainerStyle>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="IsExpanded" Value="True" />
</Style>
</TreeView.ItemContainerStyle>
</TreeView>
</Grid>
</Window>
最后，以编程方式加载数据，例如在启动时：
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
string xml = @"<plan xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xsi:noNamespaceSchemaLocation=""schema.xsd"">
<nagłówek>
<autorzy>
<nazwa>Autorzy:</nazwa>
<autor atr=""one"">
<numer>222</numer>
<imię>Rust</imię>
<nazwisko>Snow</nazwisko>
</autor>
<autor>
<numer>111</numer>
<imię>Ian</imię>
<nazwisko>Nower</nazwisko>
</autor>
</autorzy>
</nagłówek>
</plan>
";
var plan = XmlSerializationHelper.LoadFromXML<plan>(xml);
var xml2 = plan.GetXml();
Debug.WriteLine(xml2); // For testing
var children = new List<plan>();
children.Add(plan);
treeView1.Items.Clear();
treeView1.ItemsSource = children;
}
}
这会生成如下所示的内容：
您会想要用更漂亮的东西替换每个模板。
老实说，在研究完所有这些之后，我现在相信 WinForms 树 。
更新 - 编辑
Re-reading 你的问题，我看到你的要求是允许用户 load, edit in tree, and 保存 XML。这比加载更复杂。以下是步骤：
首先，添加用于加载和保存的自定义路由 UI 命令 XML:
public static class CustomCommands
{
public static readonly RoutedUICommand LoadXMLCommand = new RoutedUICommand("Load XML", "LoadXML", typeof(Window1));
public static readonly RoutedUICommand SaveXMLCommand = new RoutedUICommand("Save XML", "SaveXML", typeof(Window1));
}
接下来，在您的 Window1 class 中为这些操作添加实际的 c# 逻辑：
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
private void ExecutedLoadXML(object sender, ExecutedRoutedEventArgs e)
{
string xml = @"<plan xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xsi:noNamespaceSchemaLocation=""schema.xsd"">
<nagłówek>
<autorzy>
<nazwa>Autorzy:</nazwa>
<autor atr=""one"">
<numer>222</numer>
<imię>Rust</imię>
<nazwisko>Snow</nazwisko>
</autor>
<autor>
<numer>111</numer>
<imię>Ian</imię>
<nazwisko>Nower</nazwisko>
</autor>
</autorzy>
</nagłówek>
</plan>
";
var plan = XmlSerializationHelper.LoadFromXML<plan>(xml);
var children = new List<plan>();
children.Add(plan);
treeView1.ItemsSource = null;
treeView1.Items.Clear();
treeView1.ItemsSource = children;
}
private void ExecutedSaveXML(object sender, ExecutedRoutedEventArgs e)
{
var planList = treeView1.ItemsSource as IList<plan>;
if (planList != null && planList.Count > 0)
{
// Kludge to force pending edits to update
treeView1.Focus();
// Replace with actual save code!
Debug.WriteLine(planList[0].GetXml());
}
}
}
如您所见，我只是从硬编码字符串加载，并通过调试写入行进行保存。你会想用真正的逻辑替换它们。
接下来，在XAML中，将上面定义的命令添加到<Window.CommandBindings>
然后，在XAML中添加一个ToolBarTray和ToolBar，带有加载和保存按钮XML，并将按钮绑定到您添加到CommandBindings 以上。
最后，在 XAML 中，对于每个包含数据字段的 DataTemplate 或 HierarchicalDataTemplate，将该字段的 TextBlock 替换为适当的框架元素以进行编辑.根据需要添加任何标签作为额外的 TextBlocks，并将它们全部包装在一个容器中，例如 Grid.
这是有效的方法：
<Window x:Class="WpfTreeViewNew.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="Window1" Height="300" Width="600">
<Window.CommandBindings>
<CommandBinding Command="w:CustomCommands.LoadXMLCommand" Executed="ExecutedLoadXML"/>
<CommandBinding Command="w:CustomCommands.SaveXMLCommand" Executed="ExecutedSaveXML"/>
</Window.CommandBindings>
<Window.Resources>
<HierarchicalDataTemplate DataType="{x:Type w:plan}" ItemsSource="{Binding Path=Items}">
<TextBlock Text="Plan">

</HierarchicalDataTemplate >
<HierarchicalDataTemplate DataType="{x:Type w:planNagłówek}" ItemsSource="{Binding Path=autorzy}">
<TextBlock Text="Nagłówek">
</TextBlock>
</HierarchicalDataTemplate >
<HierarchicalDataTemplate DataType="{x:Type w:planNagłówekAutorzy}" ItemsSource="{Binding Path=autor}">
<Grid Margin="3" MinWidth="300">
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="nazwa:" Grid.Column="0" Grid.Row="0"/>
<TextBox Text="{Binding Path=nazwa, Mode=TwoWay}" Grid.Column="1" Grid.Row="0"/>
</Grid>
</HierarchicalDataTemplate >

<TextBlock Text="numer:" Grid.Column="0" Grid.Row="1"/>
<TextBox Text="{Binding Path=numer, Mode=TwoWay}" Grid.Column="1" Grid.Row="1"/>
<TextBlock Text="imię:" Grid.Column="0" Grid.Row="2"/>
<TextBox Text="{Binding Path=imię, Mode=TwoWay}" Grid.Column="1" Grid.Row="2"/>
<TextBlock Text="nazwisko:" Grid.Column="0" Grid.Row="3"/>
<TextBox Text="{Binding Path=nazwisko, Mode=TwoWay}" Grid.Column="1" Grid.Row="3"/>
</Grid>
</Border>
</DataTemplate >
</Window.Resources>
<DockPanel>
<ToolBarTray DockPanel.Dock="Top">
<ToolBar>
<Button Command="w:CustomCommands.LoadXMLCommand" Content="{Binding RelativeSource={RelativeSource Self}, Path=Command.Text}"/>
<Button Command="w:CustomCommands.SaveXMLCommand" Content="{Binding RelativeSource={RelativeSource Self}, Path=Command.Text}"/>
</ToolBar>
</ToolBarTray>
<Grid DockPanel.Dock="Bottom">
<TreeView Margin="3" Name="treeView1">
<TreeView.ItemContainerStyle>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="IsExpanded" Value="True" />
</Style>
</TreeView.ItemContainerStyle>
</TreeView>
</Grid>
</DockPanel>
</Window>
它产生的 UI 看起来像：
我不是 UI 设计师，所以你会想用这个来获得更漂亮的东西。

public static string GetXml<T>(T obj, XmlSerializer serializer, bool omitStandardNamespaces)
{
using (var textWriter = new StringWriter())

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true; // For cosmetic purposes.
settings.IndentChars = " "; // For cosmetic purposes.
using (var xmlWriter = XmlWriter.Create(textWriter, settings))
{
if (omitStandardNamespaces)
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", ""); // Disable the xmlns:xsi and xmlns:xsd lines.
serializer.Serialize(xmlWriter, obj, ns);
}
else
{
serializer.Serialize(xmlWriter, obj);
}
}
return textWriter.ToString();
}
}
public static string GetXml<T>(this T obj, bool omitNamespace)

XmlSerializer serializer = new XmlSerializer(obj.GetType());
return GetXml(obj, serializer, omitNamespace);
}
public static string GetXml<T>(this T obj)

}
public static T LoadFromXML<T>(this string xmlString)

}
public static T LoadFromXML<T>(this string xmlString, XmlSerializer serial)
{
T returnValue = default(T);
using (StringReader reader = new StringReader(xmlString))
{
object result = serial.Deserialize(reader);
if (result is T)
{
returnValue = (T)result;
}
}
return returnValue;
}
public static T LoadFromFile<T>(string filename)
{

using (var fs = new FileStream(filename, FileMode.Open))
{
object result = serial.Deserialize(fs);
if (result is T)

首先，添加用于加载和保存的自定义路由 UI 命令 XML:
public static class CustomCommands
{
public static readonly RoutedUICommand LoadXMLCommand = new RoutedUICommand("Load XML", "LoadXML", typeof(Window1));
public static readonly RoutedUICommand SaveXMLCommand = new RoutedUICommand("Save XML", "SaveXML", typeof(Window1));
}
接下来，在您的 Window1 class 中为这些操作添加实际的 c# 逻辑：
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
private void ExecutedLoadXML(object sender, ExecutedRoutedEventArgs e)
{
string xml = @"<plan xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xsi:noNamespaceSchemaLocation=""schema.xsd"">
<nagłówek>
<autorzy>
<nazwa>Autorzy:</nazwa>
<autor atr=""one"">
<numer>222</numer>
<imię>Rust</imię>
<nazwisko>Snow</nazwisko>
</autor>
<autor>
<numer>111</numer>
<imię>Ian</imię>
<nazwisko>Nower</nazwisko>
</autor>
</autorzy>
</nagłówek>
</plan>
";
var plan = XmlSerializationHelper.LoadFromXML<plan>(xml);
var children = new List<plan>();
children.Add(plan);
treeView1.ItemsSource = null;
treeView1.Items.Clear();
treeView1.ItemsSource = children;
}
private void ExecutedSaveXML(object sender, ExecutedRoutedEventArgs e)
{
var planList = treeView1.ItemsSource as IList<plan>;
if (planList != null && planList.Count > 0)
{
// Kludge to force pending edits to update
treeView1.Focus();
// Replace with actual save code!
Debug.WriteLine(planList[0].GetXml());
}
}
}
如您所见，我只是从硬编码字符串加载，并通过调试写入行进行保存。你会想用真正的逻辑替换它们。
接下来，在XAML中，将上面定义的命令添加到<Window.CommandBindings>
然后，在XAML中添加一个ToolBarTray和ToolBar，带有加载和保存按钮XML，并将按钮绑定到您添加到CommandBindings 以上。
最后，在 XAML 中，对于每个包含数据字段的 DataTemplate 或 HierarchicalDataTemplate，将该字段的 TextBlock 替换为适当的框架元素以进行编辑.根据需要添加任何标签作为额外的 TextBlocks，并将它们全部包装在一个容器中，例如 Grid.
这是有效的方法：

它产生的 UI 看起来像：
我不是 UI 设计师，所以你会想用这个来获得更漂亮的东西。

GetXML()扩展方法：
public static class XmlSerializationHelper
{
public static string GetXml<T>(T obj, XmlSerializer serializer, bool omitStandardNamespaces)
{
using (var textWriter = new StringWriter())
{
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true; // For cosmetic purposes.
settings.IndentChars = " "; // For cosmetic purposes.
using (var xmlWriter = XmlWriter.Create(textWriter, settings))
{
if (omitStandardNamespaces)
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", ""); // Disable the xmlns:xsi and xmlns:xsd lines.
serializer.Serialize(xmlWriter, obj, ns);
}
else
{
serializer.Serialize(xmlWriter, obj);
}
}
return textWriter.ToString();
}
}
public static string GetXml<T>(this T obj, bool omitNamespace)
{
XmlSerializer serializer = new XmlSerializer(obj.GetType());
return GetXml(obj, serializer, omitNamespace);
}
public static string GetXml<T>(this T obj)
{
return GetXml(obj, false);
}
public static T LoadFromXML<T>(this string xmlString)
{
return xmlString.LoadFromXML<T>(new XmlSerializer(typeof(T)));
}
public static T LoadFromXML<T>(this string xmlString, XmlSerializer serial)
{
T returnValue = default(T);
using (StringReader reader = new StringReader(xmlString))
{
object result = serial.Deserialize(reader);
if (result is T)
{
returnValue = (T)result;
}
}
return returnValue;
}
public static T LoadFromFile<T>(string filename)
{
XmlSerializer serial = new XmlSerializer(typeof(T));
try
{
using (var fs = new FileStream(filename, FileMode.Open))
{
object result = serial.Deserialize(fs);
if (result is T)
{
return (T)result;
}
}
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString());
throw;
}
return default(T);
}
}
