从WinForm关闭WPF窗口 [英] Closing a WPF Window from a WinForm

问题描述

所以在我的Program.CS中，我在不同的线程上运行WPF和WinForm。在我的程序中有一点弹出WinForm。我需要这个WinForm来查找和关闭WPF窗口，或者窗口检测WinForm是否打开和关闭。有关如何做到这一点的任何想法？我一直在寻找运气。

So in my Program.CS I run both a WPF and a WinForm on separate threads. At one point in my program a WinForm pops up. I need this WinForm to either find and close the WPF window, or the window to detect that the WinForm is open and close itself. Any idea on how I could do this? I''ve been searching with no luck.

推荐答案

你为什么要在如此复杂的环境中工作？无论如何，您可以使用类 System.Windows.Interop.WindowInteropHelper 找到顶级WPF窗口的句柄：

http://msdn.microsoft.com/en-us/library/system.windows.interop。 windowinterophelper.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.windows.interop.windowinterophelper.handle.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/sy stem.windows.interop.windowinterophelper.ensurehandle.aspx [ ^ ]。



然后您只需使用Windows API关闭它：http://msdn.microsoft.com/en-us/library/ windows / desktop / ms632678％28v = vs.85％29.aspx [ ^ ]。



这是你怎么做的通过P / Invoke进行.NET项目： http://www.pinvoke.net/default.aspx/user32.closewindow [ ^ ]。



但请更好地检查整个设计。







随着 System.Windows.Forms 一起，您可以找到大量样本，在CodeProject上。有些就足够了： http://www.codeproject.com/search.aspx？ doctypeid = 1& q = Forms + splash [ ^ ]。

Why are you working in such complicated settings? Anyway, you can find a handle of the top-level WPF window using the class System.Windows.Interop.WindowInteropHelper:
http://msdn.microsoft.com/en-us/library/system.windows.interop.windowinterophelper.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.interop.windowinterophelper.handle.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.interop.windowinterophelper.ensurehandle.aspx[^].

And then you can simply use Windows API to close it: http://msdn.microsoft.com/en-us/library/windows/desktop/ms632678%28v=vs.85%29.aspx[^].

This is how can you do it in .NET project via P/Invoke: http://www.pinvoke.net/default.aspx/user32.closewindow[^].

But better review your whole design.



With System.Windows.Forms along, you can find a good number of samples, on CodeProject along. Some will be good enough: http://www.codeproject.com/search.aspx?doctypeid=1&q=Forms+splash[^].
