WPF 中图像填充按钮上的空间

I have Button在我的 WPF 应用程序上，我想要一个Image来填补Button完全地。目前我有以下代码，它没有填充Button.

<Image x:Key="MyResource" Source="Images/up-arrow-icon.jpg" Margin="0" />

<telerik:RadButton  Height="25" Width="40" HorizontalAlignment="Left" Margin="417,10,0,0" 
                    Name="radButton1" VerticalAlignment="Top" Click="UpButtonClick">
    <telerik:RadButton.Content>
        <StaticResource ResourceKey="MyResource"/>
    </telerik:RadButton.Content>
</telerik:RadButton>

我需要调整大小吗Image那么在WPF之外使用它吗？

你可以尝试改变你的Image to an ImageBrush然后将其分配给您的BackGround然后您的图像将拉伸到按钮的内表面。

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <ImageBrush x:Key="MyResource" ImageSource="C:\temp\test.jpg" />
    </Window.Resources>
    <Grid>
        <Button Height="25" Background="{StaticResource MyResource}" Width="40" HorizontalAlignment="Left" Margin="417,10,0,0" VerticalAlignment="Top"/>
    </Grid>
</Window>

或者将 TextBlock 添加到按钮内容并将图像指定为背景。

<Window.Resources>
    <ImageBrush x:Key="MyResource" ImageSource="C:\temp\test.jpg" />
</Window.Resources>
<Grid>
    <Button Height="25"  Width="40" HorizontalAlignment="Left" Margin="417,10,0,0" VerticalAlignment="Top">
        <Button.Content>
            <TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="34" Height="19" Margin="0">
                <TextBlock.Background>
                    <StaticResource ResourceKey="MyResource"/>
                </TextBlock.Background>
            </TextBlock>
        </Button.Content>
    </Button>
</Grid>
