Write a C# Sharp program to compare the current string instance with another string

using System;
public class Example33
{
   public static void Main()
   {
      string str1 = "Goodbye";
      string str2 = "Hello";
      string str3 = "a small string";
      string str4 = "goodbye";
      // Compare a string to itself.
      Console.WriteLine(CompareStrings(str1, str1));
      Console.WriteLine(CompareStrings(str1, str2));
      Console.WriteLine(CompareStrings(str1, str3));
      // Compare a string to another string that varies only by case.
      Console.WriteLine(CompareStrings(str1, str4));
      Console.WriteLine(CompareStrings(str4, str1));
   }
   private static string CompareStrings( string str1, string str2 )
   {
      // Compare the values, using the CompareTo method on the first string.
      int cmpVal = str1.CompareTo(str2);

	   if (cmpVal == 0) // The strings are the same.
         return "The strings occur in the same position in the sort order.";
      else if (cmpVal > 0)
         return "The first string precedes the second in the sort order.";
      else
         return "The first string follows the second in the sort order.";
    }
}
