如何检查WPF控件是否托管在WinForms中？

Question

我有一个WPF控件，它在某些情况下作为WPF应用程序的组件存在，另一个控件在Windows窗体中。我如何检测第二种情况（WPF控件是嵌入在WinForms中）？

试试这个：

HwndSource wpfHandle = PresentationSource.FromVisual(this) as HwndSource; 
if (wpfHandle != null) 
{ 
    ElementHost host = System.Windows.Forms.Control.FromChildHandle(wpfHandle.Handle) as ElementHost; 
    if(host != null) 
    { 
     //hosted in ElementHost... 
    } 
}
