Csharp/C Sharp/Collections Data Structure/SortedList

Add element to SortedList

    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

 
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

 
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);
        }
    }
}
