how to get a thread's handle

[huajiao]

i want to use the API:
PostMessage(IntPtr hWnd, int Msg, int wParam, int lParam)
to post message to a thread.
so i need the thread's handle.
thanks!

The syntax of this function is:
BOOL PostMessage(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam
);
where hWnd is a handle to a window.
If you want to post a message to a thread you should take a look at
BOOL PostThreadMessage(
DWORD idThread,
UINT Msg,
WPARAM wParam,
LPARAM lParam
);

AppDomain.GetCurrentThreadId()

Does that return the actual OS thread id? I was under the impression that
it was an internal logical thread id since the mapping of the managed thread
object to the OS "real" thread used can change.

Yes it does (currently). But it might not be guaranteed to do so in
future versions.
