1、添加应用（Ajax.dll）。

<add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" />
</httpHandlers>
</system.web>
<httpHandlers>
<add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" />
</httpHandlers>
</system.web>
3、c#
using System;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Ajax.Utility.RegisterTypeForAjax(typeof(_Default));
}
{
return firstNumber + secondNumber;
}
}
{
protected void Page_Load(object sender, EventArgs e)
{
Ajax.Utility.RegisterTypeForAjax(typeof(_Default));
}
[Ajax.AjaxMethod()]
{
return firstNumber + secondNumber;
}
}
4、aspx
