How to print function name without hard code string?

Question

c language has macro like FILE/LINE to print file name and code line number

So how does C# language achieve same goal, is it possible to do, or require assembly packages?

Thanks a lot.

Your question title and question body seem to be at odds with each other. Can you make them ask the same thing? — DiplomacyNotWar, Mar 13 '20 at 06:56

@Sweeper See I thought OP meant `nameof()` going by the question title. — DiplomacyNotWar, Mar 13 '20 at 06:58
I am confident this is a x-y-Question. What do want to do? (In other words: what do you need file/line for?) — Fildor, Mar 13 '20 at 07:20

You can use StackFrame, i would be wary about doing this though, it will come at a performance cost and is likely to give you issues in release .

Represents a stack trace, which is an ordered collection of one or more stack frames.

var stackTrace = new StackTrace(0, true);
var sf = stackTrace.GetFrame(0);
Console.WriteLine("FileName: {0}", sf.GetFileName());
Console.WriteLine("Line Number:{0} ",sf.GetFileLineNumber());
Console.WriteLine("Function Name:{0}",sf.GetMethod ());
