How to get the function name from function pointer in C#?

I have a function which takes a function pointer

like

public void myfunc<a,b>(Func<a,b> functionpointer)
{
  String functionname;
  // Do some magic to get functionpointers name and set it to functionname
 }

Is it possible to get the function's name without running it?

I know that you can get the function name of the currently running function, but how do you get the name of a function that you're going to call?

Forgive me if such a question might have been posted before, i can't find a solution for it in C#

Use Reflection

 foreach (Type objType in assembly.GetTypes())
                {
                    //List<string> listInner = new List<string>();
                    var listInner = new HashSet<string>();
                    listInner.Add(objType.FullName);
                    foreach (MemberInfo obMember in objType.GetMembers())
                    {
                        listInner.Add(obMember.MemberType + " " + obMember.ToString());

                    }
                 }

public void myfunc<a, b>(Expression<Func<a, b>> expr)
{
    Func<a, b> functionpointer = expr.Compile();

    String functionname = "";
    var mce = expr.Body as MethodCallExpression;
    if(mce!=null)
    {
        functionname = mce.Method.Name;
    }
}

You can use MemberInfo.Name Property

string functionname = functionpointer.Method.Name;
