How to check if a process is suspended? - Not not responding

I am writing a C# console application to find if there are any OUTLOOK processes which are suspended. Occasionally on our Terminal server, Outlook will lock up on a session and will get stuck as "Suspended" in Task Manager.

I found this code on a website as an example to checking if a notepad process is suspended:

var proc = Process.GetProcessesByName("notepad");
var isSuspended = proc[0].Threads[0].ThreadState == ThreadState.Suspended;

I tried this exact code, but the only ThreadStates that are possible are:

- Initalized
- Ready
- Running
- Standby
- Terminated
- Transition
- Unknown
- Wait.

There isn't one for "Suspended" as far as I can see. Is there an alternative method for checking for suspended processes?

Having established that the thread is waiting via it's ThreadState, you can examine the WaitReason property of the ProcessThread and see if that says it's Suspended.

Obviously, there are timing issues with performing tests such as these, since the other process is outside of your control.
