删除 WPF 中动态超链接的下划线

Question

我创建了 WPF 应用程序。在某种形式下，用户将 richtextbox 的选定文本更改为 hyperlink。我搜索了一个多小时并寻找解决方案。但是不能。我的动态超链接创建如下：

                var textRange = RichTextBox.Selection;
                textRange.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Blue);

                var hyperlink = new Hyperlink(textRange.Start, textRange.End)
                {
                    IsEnabled = true,
                    Foreground = Brushes.Blue
                };

                hyperlink.NavigateUri = new Uri("http://search.msn.com/" + firstOrDefault.WordId);
                var main = new WordMain();
                hyperlink.Click += new RoutedEventHandler(main.hyperLink_Click);
                RichTextBox.IsDocumentEnabled = true;
                RichTextBox.IsReadOnly = false;

如何去除动态超链接的下划线。我想用textdecoration，代码不行

Answer 1

我刚刚试过了，效果很好
Xaml

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid x:Name="Root">
        <TextBlock x:Name="TextBl"></TextBlock>
    </Grid>
</Window>

代码隐藏

Run run = new Run("Whosebug");
Hyperlink hyper = new Hyperlink(run);
hyper.NavigateUri = new Uri("http://whosebug.com");
hyper.TextDecorations = null;
TextBl.Inlines.Add(hyper);

从您的 C# 代码中删除颜色格式并将其放入您的 App.xaml 文件中：

<Application.Resources>
    ...
    <TextDecorationCollection x:Key="_textDeco_hyperlink">
        <!--<TextDecoration Location="Underline" />-->
    </TextDecorationCollection>

    <Style TargetType="{x:Type Hyperlink}">
        <Setter Property="Foreground" Value="Black"/>
        <Setter Property="Background" Value="Khaki" />
        <Setter Property="ForceCursor" Value="True" />
        <Setter Property="Cursor" Value="Hand" />
        <Setter Property="TextDecorations" Value="{DynamicResource _textDeco_hyperlink}" />
        <Setter Property="IsEnabled" Value="False" />
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Foreground" Value="Khaki" />
                <Setter Property="Background" Value="Black" />
            </Trigger>
        </Style.Triggers>
    </Style>
    ...
<Application.Resources>

如果这不起作用，我认为这是序列化和反序列化 FlowDocument 的方式。试试这个：

// Store your FlowDocument as a list of strings
List<string> blocksAsStrings = FlowDoc_store(_docSelected._Rtb.Document);
...
// Load your FlowDocument into your RichTextBox
rtb.Document = FlowDoc_load(blocksAsStrings);

/// <summary>
/// Stores a FlowDocument as a list of strings, each string represents a Block.
/// </summary>
public static List<string> FlowDoc_store(FlowDocument flowDoc)
{
    List<string> blocksAsStrings = new List<string>(flowDoc.Blocks.Count);

    foreach (Block block in flowDoc.Blocks)
    {
        blocksAsStrings.Add(XamlWriter.Save(block));
    }

    return blocksAsStrings;
}

/// <summary>
/// Loads a FlowDocument from a list of strings, each string represents a Block.
/// </summary>
public static FlowDocument FlowDoc_load(List<string> blocksAsStrings)
{
    FlowDocument flowDoc = new FlowDocument();

    foreach (string blockAsString in blocksAsStrings)
    {
        using (StringReader stringReader = new StringReader(blockAsString))
        {
            using (XmlReader xmlReader = XmlReader.Create(stringReader))
            {
                Block block = (Block)XamlReader.Load(xmlReader);
                flowDoc.Blocks.Add(block);
            }
        }
    }

    return flowDoc;
}

对于从搜索结果来到这里寻找简单答案并且不在乎保留任何装饰（例如使用图像时）的任何人：

<Hyperlink ... TextDecorations="">
   ...
</Hyperlink>
