Write C# Sharp program to demonstrate that the Compare(String, String, Boolean) method is equivalent to using ToUpper or ToLower when comparing strings

using System;
class Example26
{
   static void Main()
   {
      // Create upper-case characters from their Unicode code units.
      String stringUpper = "\x0051\x0052\x0053";
      // Create lower-case characters from their Unicode code units.
      String stringLower = "\x0071\x0072\x0073";
      // Display the strings.
      Console.WriteLine("Comparing '{0}' and '{1}':", 
                        stringUpper, stringLower);
      // Compare the uppercased strings; the result is true.
      Console.WriteLine("The Strings are equal when capitalized? {0}",
                        String.Compare(stringUpper.ToUpper(), stringLower.ToUpper()) == 0 
                                       ? "true" : "false");
      // The previous method call is equivalent to this Compare method, which ignores case.
      Console.WriteLine("The Strings are equal when case is ignored? {0}",
                        String.Compare(stringUpper, stringLower, true) == 0
                                       ? "true" : "false" );
   }
}
