Tamir,

In order to do this, you will have to instantiate a new instance of the
StackFrame class. You need to pass 1 to the constructor to let it know to
go up one frame in the stack. Once you have that, you can call the
GetMethod method to get the MethodBase implementation representing the
method that called you. Finally, use the Name property to get the name.

Hope this helps.
 
How can I know who called the certain method of some object (from which
class/method it was called)

E.G.
class A
{
Public A()
{
B b = new B();
}
Private Some()
{
b.Caller();
}
}
Class B
{
Public Caller()
{
Console.WriteLine ("Called from {0}",WHO_CALL_ME);
}
}

Output: "Called from A.Some()"

And furthermore, you'll need to disable inlining for the method(s) as
appropriate (see MethodImplAttribute).

Might I ask why you want this? It will be awkward and slow. Perhaps you
could define some sort of interface that the callee takes, with the callers
constructing the appropriate object.

Hope this helps.

Great, thank you. The only one small thing leave. How to get the class of
method called?

I need it for debugging in multithread enviroment. Are you know better
method to do it?

Hi,
Use MethodBase.GetCurrentMethod() or (new
StackTrace()).GetFrame(1).GetMethod() and convert that to MethodInfo
type. Then retrieve the information regarding that method.

This method is VERY slow, so be sure you don't do it in a performance
critical section of your code, and benchmark the result to be sure it's
acceptable.
