Add element to SortedList

<source lang="csharp">

   using System;
   using System.Collections;

class Class1 {

  static void Main(string[] args) {
     bool ByEmp = false;
     SortedList Emps = new SortedList();
     Emps.Add("500", "A");
     Emps.Add("502", "C");
     Emps.Add("501", "B");
     Emps.Add("503", "D");
     
     for(int k=0; k<Emps.Count; k++) {
       Console.WriteLine("\t{0}\t{1}", Emps.GetKey(k), Emps.GetByIndex(k));
     }
  }

}

Add to SortedList, get by key and index

<source lang="csharp"> using System; using System.Collections; using System.Collections.Generic; using System.Text; class Program {

   static void Main(string[] args) {
       SortedList footballTeams = new SortedList();
       footballTeams.Add(1, "S");
       footballTeams.Add(2, "K");
       footballTeams.Add(3, "I");
       for (int i = 0; i < footballTeams.Count; i++) {
           Console.WriteLine("KEY: " + footballTeams.GetKey(i) +
              "   VALUE: " + footballTeams.GetByIndex(i));
       }
   }

}

Delete element in a SortedList with RemoveAt

<source lang="csharp"> using System; using System.Collections;

public class MainClass {

   public static void Main() {
       SortedList list = new SortedList();
       list.Add("G", "B");
       list.Add("Ae", "Sm");
       list.Add("Ay", "G");
       list.Add("Ab", "S");
       list.Add("W", "C");
       list.Remove("Abraxus");
       list.RemoveAt(2);
       String artist = (string)list["Ay"];
       Console.WriteLine(artist);
       String error = (string)list["S"];
       Console.WriteLine(error);
       foreach (DictionaryEntry d in list) {
           Console.WriteLine("{0}, {1}", d.Key, d.Value);
       }
