int16collection.cs

ajax的应用实例 是个很好的学习例子 对初学者用很打帮助

using System;
using System.Collections;

namespace AJAXDemo.Examples.Collections
{
	public class Int16Collection : CollectionBase  
	{

		public Int16 this[ int index ]  
		{
			get  
			{
				return( (Int16) List[index] );
			}
			set  
			{
				List[index] = value;
			}
		}

		public int Add( Int16 value )  
		{
			return( List.Add( value ) );
		}

		public int IndexOf( Int16 value )  
		{
			return( List.IndexOf( value ) );
		}

		public void Insert( int index, Int16 value )  
		{
			List.Insert( index, value );
		}

		public void Remove( Int16 value )  
		{
			List.Remove( value );
		}

		public bool Contains( Int16 value )  
		{
			// If value is not of type Int16, this will return false.
			return( List.Contains( value ) );
		}

		protected override void OnInsert( int index, Object value )
