You can use it by using the StackTrace and then you can get reflective types from that   StackTrace stackTrace   new StackTrace                 get call stack StackFrame   stackFrames   stackTrace GetFrames        get method calls  frames   StackFrame callingFrame   stackFrames 1   MethodInfo method   callingFrame GetMethod    Console Write method Name   Console Write method DeclaringType Name

Yes  in principe it is possible  but it doesn t come for free   You need to create a StackTrace  and then you can have a look at the StackFrame s of the call stack

public class SomeClass       public void SomeMethod                 StackFrame frame   new StackFrame 1           var method   frame GetMethod            var type   method DeclaringType          var name   method Name            Now let s say you have another class like this   public class Caller      public void Call              SomeClass s   new SomeClass          s SomeMethod             name will be  Call  and type will be  Caller   UPDATE Two years later since I m still getting upvotes on this  In  Net 4 5 there is now a much easier way to do this  You can take advantage of the CallerMemberNameAttribute  Going with the previous example   public class SomeClass       public void SomeMethod  CallerMemberName string memberName                     Console WriteLine memberName     output will be name of calling method

Technically  you can use StackTrace  but this is very slow and will not give you the answers you expect a lot of the time  This is because during release builds optimizations can occur that will remove certain method calls  Hence you can t be sure in release whether stacktrace is  correct  or not   Really  there isn t any foolproof or fast way of doing this in C   You should really be asking yourself why you need this and how you can architect your application  so you can do what you want without knowing which method called it

It s actually something that can be done using a combination of the current stack-trace data  and reflection   public void MyMethod          StackTrace stackTrace   new System Diagnostics StackTrace         StackFrame frame   stackTrace GetFrames   1        MethodInfo method   frame GetMethod         string methodName   method Name       Type methodsClass   method DeclaringType      The 1 index on the StackFrame array will give you the method which called MyMethod
