How to suspend current windows thread in C#

I don't know whether this will work or not as it returns a pseudo-handle but try passing to SuspendThread() the handle obtained from another API function, GetCurrentThread, whose P/Invoke signature is:

[DllImport("kernel32.dll")]
static extern IntPtr GetCurrentThread();

and which can be called with:

IntPtr hThread = GetCurrentThread();

hello

i used the suspendthread() method but this program is still not responding because the handle and state property doesnot return any value, i want to suspend thread when it is its initial state that is 0 but this program still not working plz check the code and reply me
thanks alot
bye
