1.创建工程

文件-> 新建->网站 如下图。

bubuko.com,布布扣

 

工程建好后,会自动添加如下代码:

bubuko.com,布布扣
 1 using System;
 2 using System.Linq;
 3 using System.Web;
 4 using System.Web.Services;
 5 using System.Web.Services.Protocols;
 6 using System.Xml.Linq;
 7 
 8 [WebService(Namespace = "http://tempuri.org/")]
 9 [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
10 // 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。
11 // [System.Web.Script.Services.ScriptService]
12 public class Service : System.Web.Services.WebService
13 {
14     public Service () {
15 
16         //如果使用设计的组件,请取消注释以下行 
17         //InitializeComponent(); 
18     }
19 
20     [WebMethod]
21     public string HelloWorld() {
22         return "Hello World";
23     }
24     
25 }
bubuko.com,布布扣

 

可以运行一遍看看效果。

2.添加代码增强webservice的功能

增加加减乘除的功能。

代码如下:

bubuko.com,布布扣
 1 using System;
 2 using System.Linq;
 3 using System.Web;
 4 using System.Web.Services;
 5 using System.Web.Services.Protocols;
 6 using System.Xml.Linq;
 7 
 8 [WebService(Namespace = "http://tempuri.org/")]
 9 [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
10 // 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。
11 // [System.Web.Script.Services.ScriptService]
12 public class Service : System.Web.Services.WebService
13 {
14     public Service () {
15 
16         //如果使用设计的组件,请取消注释以下行 
17         //InitializeComponent(); 
18     }
19 
20 
21     //[WebMethod]
22     //public string HelloWorld()
23     //{
24     //    return "Hello World";
25     //}
26 
27     [WebMethod(Description = "求和的方法")]
28     public double addition(double i, double j)
29     {
30         return i + j;
31     }
32 
33     [WebMethod(Description = "求差的方法")]
34     public double subtract(double i, double j)
35     {
36         return i - j;
37     }
38 
39     [WebMethod(Description = "求积的方法")]
40     public double mutiplication(double i, double j)
41     {
42         return i * j;
43     }
44 
45     [WebMethod(Description = "求商的方法")]
46     public double division(double i, double j)
47     {
48         if(j!=0)
49             return i/j;
50         else
51             return 0;
52     }
53 }
bubuko.com,布布扣

运行效果如下:

bubuko.com,布布扣

 

3.使用生成的webservice

VS2008-> 文件->新建->网站->ASP.NET网站->website2

bubuko.com,布布扣

接下来添加刚才生成的webservice应用:

website2邮右键->添加web引用

bubuko.com,布布扣

URL是运行website1之后的网址(在使用刚才的webservice时,需要先把那个服务运行起来才行)

URL写好后,点击前往->添加应用->ok。

引入的web引用中有一个wsdl文件(此处对wsdl的提示与本文无关系)。wsdl文件如下:

bubuko.com,布布扣
  1 <?xml version="1.0" encoding="utf-8"?>

我们在这就练习调用webservice的四个方法,做一个简单的调用的例子,先在网站的前台添加几个控件,代码如下:

bubuko.com,布布扣
 1 <%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
 2 
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 5 <html xmlns="http://www.w3.org/1999/xhtml" >
 6  <head id="Head1" runat="server">
 7       <title>Webservice调用实例</title>
 8   </head>
 9   <body>
10       <form id="form1" runat="server">
11          <div>
12              <asp:TextBox ID="Num1" runat="server"></asp:TextBox>
13              <select id="selectOper" runat = "server">
14                  <option>+</option>
15                  <option>-</option>
16                  <option>*</option>
17                  <option>/</option>
18              </select>
19              <asp:TextBox ID="Num2" runat="server"></asp:TextBox>
20              <span id = E runat = "server"></span>
21              <asp:TextBox ID="Result" runat="server"></asp:TextBox>
22          </div>
23  </form>
24  </body>
25  </html>

到此一个一个简单的WebService的开发和调用就已经完成了,在实际应用中可以根据自己的需要,写一些功能强大的,复杂的WebService,不管多么复杂,整个流程都是这样的。

48                 case 3:
49                     Result.Text = WebserviceInstance.division(double.Parse(Num1.Text), double.Parse(Num2.Text)).ToString();
50                     break;
51             }
52         }
53     }
54 }
bubuko.com,布布扣

可以运行该网站了。
