How can I set a WPF control's color to a system color programmatically, so that it updates on color scheme changes?
提问by Csupor Jen?
How can I do this in WPF's code-behind?
我怎样才能在 WPF 的代码隐藏中做到这一点？
<Grid Background="{DynamicResource {x:Static SystemColors.DesktopBrushKey}}"/>

I just found an ugly solution:
我刚刚找到了一个丑陋的解决方案：
grid1.SetResourceReference(
Control.BackgroundProperty,
SystemColors.DesktopBrushKey);
I hope someone will post a better one (I'd like to see something like grid1.Background = BackgroundBrush, because the syntax of SetResourceReference is a step backwards from Windows Forms).
我希望有人会发布一个更好的（我希望看到类似 grid1.Background = BackgroundBrush，因为 SetResourceReference 的语法是从 Windows 窗体倒退一步）。

Extension methods might help:
扩展方法可能有帮助：
public static class FrameworkElementExtensions
{
// usage xPanel.SetBackground(SystemColors.DesktopBrushKey);
public static void SetBackground(this Panel panel, ResourceKey key)
{
panel.SetResourceReference(Panel.BackgroundProperty, key);
}
// usage xControl.SetBackground(SystemColors.DesktopBrushKey);
public static void SetBackground(this Control control, ResourceKey key)
{
control.SetResourceReference(Control.BackgroundProperty, key);
}
}

This must have been added to a later version of WPF since this was originally posted because your original code works fine for me (I'm using WPF 4.5)
这必须已添加到 WPF 的更高版本中，因为这是最初发布的，因为您的原始代码对我来说很好用（我使用的是 WPF 4.5）
<Grid Background="{DynamicResource {x:Static SystemColors.DesktopBrushKey}}"/>
<Grid Background="{DynamicResource {x:Static SystemColors.DesktopBrushKey}}"/>
