The native OS threads running in the current process are exposed through the Threads property of the Process class. Please note that this is not the same as a managed thread, these are the actual native threads running on the operating system.

In order to get a pointer to the current executing thread, we must use P/Invoke. Here's how we do it:

[DllImport("kernel32.dll")]
public static extern UInt32 GetCurrentThreadId();

UInt32 id = GetCurrentThreadId();
ProcessThread thread = Process.GetCurrentProcess().Threads.Cast().Where(t => t.Id == id).Single();
