using System;
using System.Collections;
public class SamplesSortedList  {

   public static void Main()  {
      SortedList mySL = new SortedList();
      mySL.Add( 1, "one" );
      mySL.Add( 3, "three" );
      mySL.Add( 2, "two" );
      mySL.Add( 4, "four" );
      mySL.Add( 0, "zero" );

      int myKey = 2;
      Console.WriteLine(mySL.IndexOfKey( myKey ));

   }
}
