Question

Considering that the debug data file is available (PDB) and by using either System.Reflection or another similar framework such as Mono.Cecil

Answer 1

Up to date method:

private static void Log(string text,
                        [CallerFilePath] string file = "",
                        [CallerMemberName] string member = "",
                        [CallerLineNumber] int line = 0)
{
    Console.WriteLine("{0}_{1}({2}): {3}", Path.GetFileName(file), member, line, text);
}

New Framework API which populates arguments (marked with special attributes) at runtime, see more in my answer to this SO question
