更改 WPF 按钮背景图像
Changing WPF Button Background Image
我从这里阅读了关于如何更改按钮背景图像文件的优秀建议：
How to change\set button background image in C# WPF code?
特别是以下代码：
var brush = new ImageBrush();
brush.ImageSource = new BitmapImage(new Uri("Images/ContentImage.png",UriKind.Relative));
button1.Background = brush;
除了告诉视觉工作室这是一个 "content" 文件和 "Copy Always".
好像可以，但是每当我的光标悬停在图片上时，图片就会消失。
如果我在 xaml 中指定图像文件，则不会出现此光标悬停问题。但是，我想从 C# 代码更改图像文件。
有什么建议吗？
谢谢，

为了更改 WPF 按钮背景图像，例如，在 MouseOver 事件中从 Images/ContentImage.png 更改为 Images/ContentImage1.png，您可以添加包含 Image 控件的 ControlTemplate 并使用Trigger 如以下 XAML 片段所示：
清单 1. 使用 XAML 触发器
在 MouseOver 上更改按钮图像
<Button Name="button1">
<Button.Template>
<ControlTemplate TargetType="Button">
<Image Name="img1" Source="Images/ContentImage.png" />
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="img1"
Property="Source"
Value="Images/ContentImage1.png" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
另一个解决方案将允许更改
清单 2. 单击时更改按钮图像 (XAML)
<Button Name ="button1" Click="button1_Click">
<Button.Template>
<ControlTemplate TargetType="Button">
<Image x:Name="image1">
<Image.Style>
<Style TargetType="{x:Type Image}">
<Setter Property="Source" Value="Images/ContentImage.png" />
</Style>
</Image.Style>
</Image>
</ControlTemplate>
</Button.Template>
</Button>
清单 3. 背后的 C# 代码（button1.click 事件处理程序）
private void button1_Click(object sender, RoutedEventArgs a)
{
Image _img= button1.Template.FindName("image1", button1) as Image;
Style _imgStyle = new Style { TargetType = typeof(Image) };
_imgStyle.Setters.Add(new Setter(Image.SourceProperty, new BitmapImage(new Uri(@"pack://application:,,,/YourAssemblyName;component//Images/ContentImage1.png"))));
_img.Style = _imgStyle;
}
希望这可能有所帮助。
好的，我找到了一个可行的解决方案 - 基于网页 http://www.codeproject.com/Questions/634111/How-to-remove-Glow-of-Button-on-Mouse-hover-in-WPF
一点背景知识：这是我大约十年前用 Java/Netbeans 编写的一个应用程序，多年来它变得相当大。因为Java/Netbeans不再支持s/w桌面应用程序的开发，我正在将其移植到Visual Studio WPF C#。
xaml:
<Button x:Name="buttonDigit1" HorizontalAlignment="Left" Margin="0,10,0,0" VerticalAlignment="Top" Width="30" Height="50"
Click="buttonDigit1_Click" MouseRightButtonDown="buttonDigit1_RightClick" MouseWheel="buttonDigit1_MouseWheelMoved">
<Image Width="30" Height="50"></Image>
<Button.Template>
<ControlTemplate TargetType="Button">
<Grid Background="{TemplateBinding Background}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Grid>
</ControlTemplate>
</Button.Template>
</Button>
对总共九个按钮重复此操作。

用户可以左键点击数字增加频率值，右键点击数字减少频率值。鼠标滚轮也可以做同样的事情。但是，我没有显示它的代码。
第一个答案解决了问题，但是当在 public 方法中从不同的 class 调用时就不起作用了。但是，这些信息很有用，改变了我在互联网上搜索解决方案的方法。
几天来我一直在研究这段代码以找到解决方案，是的，它可以改进。

用户可以左键点击数字增加频率值，右键点击数字减少频率值。鼠标滚轮也可以做同样的事情。但是，我没有显示它的代码。
第一个答案解决了问题，但是当在 public 方法中从不同的 class 调用时就不起作用了。但是，这些信息很有用，改变了我在互联网上搜索解决方案的方法。
几天来我一直在研究这段代码以找到解决方案，是的，它可以改进。
