How can I get the name of the calling function in C#?

Question

I need to get the name of the calling function in C#. I read about stackframe method but everywhere its said its not reliable and hurts the performance.

But I need it for production use. I am writing a custom tracer which will be logging the name of the method from which trace was called as well.

Could someone please help with a efficient method to get the calling function name? I am using Visual Studio 2010.

Answer 1

upgrade to c# 5 and use CallerMemberName

public void Method([CallerMemberName] string caller="")
{
}

EDIT

Other nice things with c# 5

public void Method([CallerMemberName] string name="",
                   [CallerLineNumber] int line=-1,
                   [CallerFilePath] string path="")
{
}

Answer 2

You can do something like:

 var stackTrace = new StackTrace();
 var name = stackTrace.GetFrame(1).GetMethod().Name;

and it work with any version of the framework/language.
