我自己也遇到过同样的问题。我在这里创建了一个开源项目http://imagebuttonwpf.codeplex.com，您可以在其中获取最新版本的图像按钮。
我不喜欢提供的“接受”解决方案有几个原因（尽管它是一个更轻量级的解决方案并且有其自身的优势）
Blockquote 这个 StackOverflow 问题的公认答案显示了一种简单的方法：WPF - How to create image button with template
主要是我认为覆盖您想要更改图像的每个按钮的控件模板是不正确的，因此我创建了一个名为 ImageButton 的自定义控件。它从按钮扩展以具有它的任何功能（尽管它可以很容易地从内容控件扩展），但还包含一个可以在不重写整个控件模板的情况下设置样式的图像。
我不喜欢每次都为我的按钮重写整个控件模板的另一个原因是我的基本按钮样式包含多个边框和动画效果，用于鼠标悬停、按下等。每次重写这些显然有其自身的冗余问题。
反正这里是 ImageButton 类
public class ImageButton : Button
{
static ImageButton() {
DefaultStyleKeyProperty.OverrideMetadata(typeof(ImageButton), new FrameworkPropertyMetadata(typeof(ImageButton)));
}
#region Dependency Properties
public double ImageSize
{
get { return (double)GetValue(ImageSizeProperty); }
set { SetValue(ImageSizeProperty, value); }
}
public static readonly DependencyProperty ImageSizeProperty =
DependencyProperty.Register("ImageSize", typeof(double), typeof(ImageButton),
new FrameworkPropertyMetadata(30.0, FrameworkPropertyMetadataOptions.AffectsRender, ImageSourceChanged));
public string NormalImage
{
get { return (string)GetValue(NormalImageProperty); }
set { SetValue(NormalImageProperty, value); }
}
public static readonly DependencyProperty NormalImageProperty =
DependencyProperty.Register("NormalImage", typeof(string), typeof(ImageButton),
new FrameworkPropertyMetadata("", FrameworkPropertyMetadataOptions.AffectsRender,ImageSourceChanged));
public string HoverImage
{
get { return (string)GetValue(HoverImageProperty); }
set { SetValue(HoverImageProperty, value); }
}
public static readonly DependencyProperty HoverImageProperty =
DependencyProperty.Register("HoverImage", typeof(string), typeof(ImageButton),
new FrameworkPropertyMetadata("", FrameworkPropertyMetadataOptions.AffectsRender, ImageSourceChanged));
public string PressedImage
{
get { return (string)GetValue(PressedImageProperty); }
set { SetValue(PressedImageProperty, value); }
}
public static readonly DependencyProperty PressedImageProperty =
DependencyProperty.Register("PressedImage", typeof(string), typeof(ImageButton),
new FrameworkPropertyMetadata("", FrameworkPropertyMetadataOptions.AffectsRender, ImageSourceChanged));
public string DisabledImage
{
get { return (string)GetValue(DisabledImageProperty); }
set { SetValue(DisabledImageProperty, value); }
}
public static readonly DependencyProperty DisabledImageProperty =
DependencyProperty.Register("DisabledImage", typeof(string), typeof(ImageButton),
new FrameworkPropertyMetadata("", FrameworkPropertyMetadataOptions.AffectsRender, ImageSourceChanged));
private static void ImageSourceChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
Application.GetResourceStream(new Uri("pack://application:,,," + (string) e.NewValue));
}
#endregion
接下来我们需要为我们的按钮提供一个默认控件模板，我从这个按钮中取出了我的大部分边框等，一个条形图，这样您就可以看到它在我们所有的样式中都被继承了
<ControlTemplate x:Key="ImageButtonTemplate" TargetType="{x:Type Controls:ImageButton}">
<Grid x:Name="Grid">
<Border x:Name="Background" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3" />
<StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center">
<Image x:Name="ButtonImage" Source="{Binding NormalImage, RelativeSource={RelativeSource TemplatedParent}}"
Height="{Binding ImageSize, RelativeSource={RelativeSource TemplatedParent}}"
Width="{Binding ImageSize, RelativeSource={RelativeSource TemplatedParent}}"/>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True" />
</StackPanel>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="ButtonImage" Property="Source" Value="{Binding HoverImage, RelativeSource={RelativeSource TemplatedParent}}" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="ButtonImage" Property="Source" Value="{Binding PressedImage, RelativeSource={RelativeSource TemplatedParent}}" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="ButtonImage" Property="Source" Value="{Binding DisabledImage, RelativeSource={RelativeSource TemplatedParent}}" />
</Trigger>
</ControlTemplate.Triggers>
那么我们当然需要新图片按钮的默认样式
<Style TargetType="{x:Type Controls:ImageButton}" BasedOn="{x:Null}">
<Setter Property="Template" Value="{StaticResource ImageButtonTemplate}" />
</Style>
当然，使用这种方法的好处是我创建了一个基于父样式的样式，它使用 Setter 来更改依赖属性（而不是需要覆盖控件模板 - 目标）
<Style x:Key="TestImageButton" TargetType="{x:Type Controls:ImageButton}" BasedOn="{StaticResource {x:Type Controls:ImageButton}}">
<Setter Property="NormalImage" Value="/ImageButton;component/Resources/clear.png"/>
<Setter Property="HoverImage" Value="/ImageButton;component/Resources/clear_green.png" />
<Setter Property="PressedImage" Value="/ImageButton;component/Resources/clear_darkgreen.png" />
<Setter Property="DisabledImage" Value="/ImageButton;component/Resources/clear_grey.png" />
</Style>
最后这意味着可以通过几种不同的方式声明按钮，或者在 XAML 中声明图像路径
<Controls:ImageButton
Content="Test Button 1"
NormalImage="/ImageButton;component/Resources/edit.png"
HoverImage="/ImageButton;component/Resources/edit_black.png"
PressedImage="/ImageButton;component/Resources/edit_darkgrey.png"
DisabledImage="/ImageButton;component/Resources/edit_grey.png"/>
或者使用样式
<Controls:ImageButton
Content="Test Button 2"
Style="{DynamicResource TestImageButton}"/>
