The following example uses the Substring method in three cases to isolate substrings within a string.

/*from   w w w .j a  v a 2 s. com*/
using System;
public class MainClass{

       String myString = "this is a test";
       string str3 = myString.Substring(3, 1); 
       Console.WriteLine(str3);
  }
