thread ID

George George

Hello everyone,

I am migrating from C++ to C#. And I am debugging a multi-threaded program and I need to print out the thread ID. In C++, I am using GetCurrentThreadID method, but in C#, I only find Thread.CurrentThread.ManagedThreadId.

My questions are,

Does Thread.CurrentThread.ManagedThreadId have the same effect and can serve my purpose?

I am confused about what means "ManagedThreadId", does there is some peer called "NonManagedThreadId"?

thanks in advance,
George

of course you would think that when I say "unique", I meant a C# keyword. Just an example of you over analysing everything.

when I said "unique", I meant the English language word UNIQUE.

Sorry Ryan,

My English is not good. From your previous reply, I think you mean unique is an C# keyword, but from MSDN search, it is not. Could you help to clarify your previous points please?

George

please tell me that you know what "unique" means.

"stable" was taken from the MSDN page where it states to use the ManagedThreadID to get a "stable" ID of a thread......"stable" meaning a unique ID that you can count on ALWAYS being unique.

Hi Ryan,

What means "unique("stable")"?

so it's pure C#, so it's managed code. You need an "identifier" of the thread, and it needs to be one that you can trust that is unique("stable"). Isn't that what the MSDN article states that ManagedThreadID is?

Thanks Ryan!

My application is pure C# application, and I want to dump thread ID to detect the behavior of each thread, so that I can find deadlock/re-entrance/how many times a thread enters a specific method, something like this.

I think from the document and your help, ManagedThreadId could serve my purpose, right?

the ManagedThreadID will work just fine.

if you would have looked up GetCurrentThreadID on MSDN, it would have given you the answer.

http://msdn.microsoft.com/en-us/library/system.appdomain.getcurrentthreadid.aspx

"AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread. http://go.microsoft.com/fwlink/?linkid=14202"
