Caller information gives information about the caller of any function. This concept was introduced in C# 5.0 . In C# 5.0 the caller info feature has introduced and using this feature we can easily get information about caller function.

These three types of attributes that are used in tracking information..

Let us take an example:

  1. using System;
  2. using System.Runtime.CompilerServices;
  3. namespace ConsApp
  4. {
  5. class Program
  6. {
  7. public void Call(string text, [CallerFilePath] string File_name = "",
  8. [CallerLineNumber] int Line = 0,
  9. [CallerMemberName] string member_name = "")
  10. {
  11. Console.WriteLine(text);
  12. Console.WriteLine(File_name);
  13. Console.WriteLine(Line);
  14. Console.WriteLine(member_name);
  15. }
  16. static void Main(string[] args)
  17. {
  18. Program Obj = new Program();
  19. Obj.Call("This is Caller Method");
  20. Console.ReadLine();
  21. }
  22. }
  23. }

Output

Before the tracking information used the StactTrack to find out the tracking information of a method that was very complicated to handle.
