Caller Information Attributes in C# 5.0

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..

• CallerFilePath: Sets the information about caller's source code file.
• CallerLineNumber: Sets the information about caller's line number.
• CallerMemberName: Sets the information about caller member name.

 

Let us take an example:

using System;
using System.Runtime.CompilerServices;
namespace ConsApp
{
    class Program
    {
        public void Call(string text, [CallerFilePath] string File_name = "",
            [CallerLineNumber] int Line = 0,
            [CallerMemberName] string member_name = "")
        {
            Console.WriteLine(text);
            Console.WriteLine(File_name);
            Console.WriteLine(Line);
            Console.WriteLine(member_name);
        }
        static void Main(string[] args)
        {
            Program Obj = new Program();
            Obj.Call("This is Caller Method");
            Console.ReadLine();
        }
    }
}

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