Hashtable.CopyTo Method copies the Hashtable elements to a one-dimensional Array instance at the specified index.

 

using System;
using System.Collections;
public class SamplesHashtable  {
   public static void Main()  {
      Hashtable mySourceHT = new Hashtable();
      mySourceHT.Add( "A", "valueA" );
