这个例子用到了上一篇博客中的Employee类，实现的功能也与之类似，不过这个代码量很少，

EmployeeService.asmx

<%@ WebService Language="C#" Class="EmployeeService" %>using System;using System.Web;using System.Web.Services;using System.Web.Services.Protocols;[WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。  [System.Web.Script.Services.ScriptService]public class EmployeeService  : System.Web.Services.WebService {    [WebMethod]    public string HelloWorld() {        return "Hello World";    }    [WebMethod]        public Employee GetEmployee(string firstName, string lastName, string title)    {        return new Employee(firstName, lastName, title);    }}

WebServiceAccess.aspx

<%@ Page Language="C#" %><!DOCTYPE html><script runat="server"></script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />    <title></title></head><body>    <form id="form1" runat="server">        <asp:ScriptManager ID="ScriptManager1" runat="server">            <Services>                <asp:ServiceReference Path="~/EmployeeService.asmx" />            </Services>        </asp:ScriptManager>        <script type="text/javascript">            function ShowEmployee(firstName, lastName, title)            {                EmployeeService.GetEmployee(firstName, lastName, title, onGetEmployeeSuccess);            }            function onGetEmployeeSuccess(employee)            {                alert(String.format("firstName:{0},lastName:{1},title{2}",employee.FirstName,employee.LastName,employee.Title));            }        </script>        <input type="button" value="Bill Gates"            onclick="ShowEmployee('Bill', 'Gates', 'Chair man')" />        <input type="button" value="Steve Ballmer"            onclick="ShowEmployee('Steve', 'Ballmer', 'CEO')" />    </form></body></html>
