1. 首先创建Web Service，注意在服务类上加[System.Web.Script.Services.ScriptService]标签。
Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services; namespace ComputingWebService
{
/// <summary>
/// Summary description for Computing
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class Computing : System.Web.Services.WebService, IComputing
{
#region IComputing Members
{
return a + b;
}
{
return new Point { X = a.X + b.X, Y = a.Y + b.Y };
}
}
}
Code

<script language="javascript">
function Button1_ClientClick()
{
var a = $get("TextBoxA").value;
var b = $get("TextBoxB").value;
ComputingWebService.Computing.Add(a, b, onComputingAddSucceeded);
}
$get("TextBoxC").value = c;
}
var bx = $get("TextBoxBX").value;
var ay = $get("TextBoxAY").value;

Codeusing System;

using System.Linq;
using System.Web;
using System.Web.Services; namespace ComputingWebService
{

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class Computing : System.Web.Services.WebService, IComputing
{
#region IComputing Members
[WebMethod]
[System.Web.Script.Services.ScriptMethod]

}
[WebMethod]
[System.Web.Script.Services.ScriptMethod]
{
return new Point { X = a.X + b.X, Y = a.Y + b.Y };
}
#endregion
}
}
2. 创建Web Application 页面，添加ScriptManager及UpdatePanel，并添加控件。
3. 在ScriptManager中，添加ServiceReference。
4. 添加OnClientClick事件javascript代码，及callback代码。

在.net 3.5中，一切变得这样轻松自然！
