How do you find the caller function? [duplicate]

Question

Closed as exact duplicate of "How can I find the method that called the current method?"

Is this possible with c#?

void main()
{
   Hello();
}

void Hello()
{
  // how do you find out the caller is function 'main'?
}

Answer 1

Console.WriteLine(new StackFrame(1).GetMethod().Name);

However, this is not robust, especially as optimisations (such as JIT inlining) can monkey with the perceived stack frames.

Answer 2

From here:

System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace(1);
System.Diagnostics.StackFrame sf = st.GetFrame(0);
string msg = sf.GetMethod().DeclaringType.FullName + "." +
sf.GetMethod().Name;
MessageBox.Show( msg );

But there is also a remark that this could not work with multi-threading.
