How to find the method name of the calling method from a method at runtime?

How do I find the method name of the calling method from a method at runtime?

For example:

Class A
{
    M1()
    {
        B.M2();
    }
}

class B
{
    public static M2()
    {
        // I need some code here to find out the name of the method that
        // called this method, preferably the name of the declared type
        // of the calling method also.
    }
}

You can do this by displaying the call stack, as illustrated in the code below. This will find the entire call stack, not just the calling method though.

void displaycallstack() {
    byte[] b;
    StackFrame sf;
    MemoryStream ms = new MemoryStream();
    String s = Process.GetCurrentProcess().ProcessName;
    Console.Out.WriteLine(s + " Call Stack");
    StackTrace st = new StackTrace();
    for (int a = 0;a < st.FrameCount; a++) {
        sf = st.GetFrame(a);
        s = sf.ToString();
        b = Encoding.ASCII.GetBytes(s);
        ms.Write(b,0,b.Length); 
    }
    ms.WriteTo(System.Console.OpenStandardOutput());
}

Better not to use StackFrame, because there are some .NET security issues. If the code is not fully trusted, the expression "new StackFrame()" will throw a security exception.

To get the current method use:

MethodBase.GetCurrentMethod().Name

About getting calling the method, see Stack Overflow question Object creation, how to resolve "class-owner"?.

Check the System.Diagnostics.Trace class, but as far as I know - there is performance price when using it

I think you are looking for:

using System.Diagnostics;

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

You can try: 

using System.Diagnostics;

StackTrace stackTrace = new StackTrace();
Console.WriteLine(stackTrace.GetFrame(1).GetMethod().Name);
