<source lang="csharp">using System;

class MainClass {

 public static void Main() {   
   string str1 = "ABCDEabcde1234567890";   
   string str2 = string.Copy(str1);  
   string str3 = "asdf";   
 
  
   // compare strings 
   if(str1 == str2)   
     Console.WriteLine("str1 == str2");   
   else   
     Console.WriteLine("str1 != str2");   
  
   if(str1 == str3)   
     Console.WriteLine("str1 == str3");   
   else   
     Console.WriteLine("str1 != str3");

str1 == str2
str1 != str3
