C# WPF XAML自定义控件看起来像LED

我想要一个看起来像LED的控件，我在这里找到了这个代码 问题是我不能让它改变颜色。当我开始键入OnColor或OffColor触发器时，它表示该成员无法识别。这是密码

}

我甚至尝试过重新构建解决方案，我确信这是我忽略的简单问题

编辑： 我将模板置于用户控制之下，忘记发布C代码来添加依赖项，但它仍然无法识别该控制。我更新了上面的代码以反映这些更改。我不熟悉使用WPF和XAML，仅当我尝试在主窗口中使用它时，UserControl中没有任何错误。XAML

类复选框（即类型）没有名为OnColor和OffColor的依赖属性

您需要创建一个新类，继承自复选框，并将这两个新的Dep道具添加到该类中

或者改为使用AttachedProperty。

你能告诉我“代码隐藏者”是谁吗？在您提到的问题中，我认为

OnColor

和

OffColor

被认为是代码隐藏的一部分，请参见。在示例中，它们显示了代码隐藏或XAML的颜色更改。我想两者都做。我还没有尝试在C#中使用它，因为它不会在XAML中注册。我会试一试，看看它在C语言中是否有效。我忘了发布添加依赖项的C语言代码，它与我链接的网站也是一样的。

    <local:LedControl IsChecked="true" IsEnabled="true" OnColor="Green" x:Name="Led1" Content="Led1" HorizontalAlignment="Left" Margin="10,33,0,0" VerticalAlignment="Top"/>
