Consider the program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            String str1;
            String str2;

            Console.Write("Enter String : ");
            str1 = Console.ReadLine();
            
            str2 = str1.Remove(0, 5);
            
            Console.WriteLine("String after remove method : " + str2);
        }
    }
}

Output

Enter String : This is India
String after remove method : is India
