a。先建一个web服务
1.新建-网站
2-添加-项目-web服务
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
/// <summary>
///WebService 的摘要说明
/// </summary>
[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，请取消对下行的注释。
// [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {
public WebService () {
//如果使用设计的组件，请取消注释以下行
//InitializeComponent();
}
[WebMethod]
public string HelloWorld() {
return "Hello World";
}
[WebMethod]
public double Sum(double a, double b)
{
return a + b;
}
[WebMethod]
public double Sub(double a, double b)
{
return a - b;
}
[WebMethod]
public double Mult(double a, double b)
{
return a * b;
}
[WebMethod]
public double Div(double a, double b)
{
return a / b;
}
}
执行
b.建立一个引用
1.添加web引用
2.添加一个index.aspx 文件

注意：
1.在实务中，建立web服务和引用是分开的，这里放在一起是便于学习。
2.a的操作生成的文件我可以把它嵌入某服务其中，然后www.xxx.net/WebService.asmx调用。
3.b的操作我可以在设置中修改部分配置，然后把这个程序放在另一个服务器中，调用。（ localhost.WebService result = new localhost.WebService();一定改一下，改成net.xxx.www.WebService result = new net.xxx.www.WebService();）
