服务端

1.新建空白解决方案，然后再空白解决方案中新建：WCF服务应用程序。建完后如图：

2.删掉自动生成的IService1.cs和Service.svc并添加WCF服务文件StudentService.svc，VS会自动生成IStudentService.cs 在添加一个Student类，如图：

![17211958-56e4b55a315a4fcbbd5bef9f89c9cfee.png][]

Student.cs:

1  /// <summary>
     2     /// DataContract数据约定,保证student类在WCF调用中被序列化
     3     /// DataMember 在被序列化的成员变量中必须加 [DataMember]标签
     4     /// </summary>
     5     [DataContract]
     6     public class Student
     7     {
     8         [DataMember]
     9         public string StudentId { get; set; }
    10         [DataMember]
    11         public string StudentName { get; set; }
    12     }

IStudentService.cs:

1      /// <summary>
     2     ///  ServiceContract：服务约定，代表我们所能操作的接口集合，提    供功能点。 
     3     ///  OperationContract: 每个对外需要发布的方法都需要加上此标签
     4     /// </summary>
     5     [ServiceContract]
     6     public interface IStudentService
     7     {
     8         [OperationContract]
     9         List<Student> RemoveStudent(string id);
    10     }

StudentService.svc:

1  public class StudentService : IStudentService
     2     {
     3 
     4         public List<Student> RemoveStudent(string id)
     5         {
     6             var students = new List<Student>() { 
     7                 new Student {StudentId="1",StudentName="学生1" }, 
     8                 new Student {StudentId="2",StudentName="学生2" } 
     9             };
    10 
    11             var student = students.Find(m => m.StudentId == id);
    12 
    13             students.Remove(student);
    14 
    15             return students;
    16         }
    17     }

到现在为止我们WCF服务端程序建好了，我们把StudentService.svc设为起始页，F5运行一下，会弹出来WCF测试客户端，如图

![17212330-dc4d8c58c46f41f1ba222a83a6bb0dd5.png][]

双击左侧的RemoveStudent(),在右侧输入值然后点击调用，如图：

![17212427-8d2f8583d8154c8498aa4d835b4d0b81.png][]

结果如我们预料的那样，StudentId为1的数据被删掉了。

接下来我们把它部署到IIS上， 在默认文档里添加StudentService.svc，然后浏览，如图：

客户端

1.新建空白解决方案，新建ASP.NET WEB应用程序，名称为WCFClient，添加服务引用，服务引用地址为上图地址中的

http://localhost:88/StudentService.svc?wsdl

,如图：![17213300-ff5ce2bc14ec41e39b925d2ecbc43957.png][]

WCFTest.aspx:

1 <form id="form1" runat="server">
     2         <div>
     3             <table>
     4                 <tr>
     5                     <td> <asp:TextBox ID="txtStudentId" runat="server"></asp:TextBox></td>
     6                      <td><asp:Button ID="btnSubmint" runat="server"  Text="删除" OnClick="btnSubmint_OnClick"/></td>
     7                 </tr>
     8             </table>
     9            
    10         </div>
    11     </form>

WCFTest.aspx.cs:

1         protected void btnSubmint_OnClick(object sender, EventArgs e)
     2         {
     3             var wcfService = new WCFService.StudentServiceClient();
     4 
     5             var str = string.Empty;
     6 
     7             wcfService.RemoveStudent(this.txtStudentId.Text.Trim())
     8                 .ToList()
     9                 .ForEach(m =>str += m.StudentId + ":" + m.StudentName);
    10 
    11             Response.Write(str);
    12         }

运行下，看下效果：
