为什么显示的不是图片而是
这样的文字

没提醒报错？<setter.value>之间是Brush类的？

把1.png和2.png加入项目中,生成操作设"resource"
<Grid>
<Button Name="bb" Width="300" Height="20">
<Button.Style>
<Style TargetType="Button" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<Image Name="ImgBtnBg" Source="1.jpg" Stretch="Fill"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Source" Value="2.jpg" TargetName="ImgBtnBg"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
