WPF Button with Image
提问by wonea
I'm trying to attach an image on a button in WPF, however this code fails. Seems strange after similar code would work perfectly in Mozilla XUL.
我正在尝试在 WPF 中的按钮上附加图像，但是此代码失败。类似的代码在 Mozilla XUL 中完美运行后似乎很奇怪。
<Button Height="49.086" Margin="3.636,12,231.795,0" Name="button2"
VerticalAlignment="Top" Grid.Column="1" Click="button2_Click"
Source="Pictures/apple.jpg">Disconnect from Server</Button>
回答by wpfwannabe
You want to do something like this instead:
你想做这样的事情：
<Button>
<StackPanel>
<Image Source="Pictures/apple.jpg" />
<TextBlock>Disconnect from Server</TextBlock>
</StackPanel>
</Button>

Another way to Stretch image to full button. Can try the below code.
另一种将图像拉伸到完整按钮的方法。可以试试下面的代码。
<Grid.Resources>
<ImageBrush x:Key="AddButtonImageBrush" ImageSource="/Demoapp;component/Resources/AddButton.png" Stretch="UniformToFill"/>
</Grid.Resources>
<Button Content="Load Inventory 1" Background="{StaticResource AddButtonImageBrush}"/>

This should do the job, no?
这应该可以完成工作，不是吗？
<Button Content="Test">
<Button.Background>
<ImageBrush ImageSource="folder/file.PNG"/>
</Button.Background>
</Button>

You can create a custom control that inherits from the Button class. This code will be more reusable, please look at the following blog post for more details: WPF - create custom button with image (ImageButton)
您可以创建一个继承自 Button 类的自定义控件。此代码将更具可重用性，请查看以下博客文章了解更多详细信息：WPF - 使用图像创建自定义按钮 (ImageButton)
Using this control:
使用此控件：

Most simple approach would be using the Image tag.
最简单的方法是使用 Image 标签。
<Button Name="btn" Width="26" Height="26" Click="btnClick">
<Image Source="Resource/btn-icon.png"/>
</Button>
Suppose your image file is added in Resource folder
假设您的图像文件已添加到 Resource 文件夹中
