一个简单的WCF实例

  在学习WCF的相关知识,写了一个非常简单的例子。

  项目结构如下:

  

   Super.Wdxt.School.Contract  类库程序,定义服务契约(主要是一些接口),引用Super.Wdxt.School.Entity  ;

   Super.Wdxt.School.Entity      类库程序,一些实体

   Super.Wdxt.School.Services   类库程序,提供对WCF服务的实现,也就是Contract项目中的接口实现类,引用Super.Wdxt.School.Entity,Super.Wdxt.School.Contract 。

   Super.Wdxt.School.Hosting    WEB应用程序,WCF的宿主程序,你可以使用不同的宿主程序比如控制台,winForm等等。引用上面三项.

    Super.Wdxt.School.Web      WEB应用程序,客户端程序。

   1.创建实体类UserInfo.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Super.Wdxt.School.Entity
{
    public class UserInfo
    {
        public int Id { get; set; }

        public string Name { get; set; }
    }

}

   2.创建服务契约IUser.cs

记得添加引用   using System.ServiceModel;  using System.ServiceModel.Web;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Super.Wdxt.School.Entity;

using System.ServiceModel;
using System.ServiceModel.Web;

namespace Super.Wdxt.School.Contract
{
    [ServiceContract]
    public interface IUser
    {
        [OperationContract]
        string GetName(int id);

        [OperationContract]
        List<UserInfo> GetList();
    }
}

   3.宿主环境  

   在Super.Wdxt.School.Hosting 添加新项-选择Wcf服务

  

   删除其.cs文件,更改User.svc如下:

<%@ ServiceHost Language="C#" Debug="true" Service="Super.Wdxt.School.Services.User" CodeBehind="Super.Wdxt.School.Services.User.cs" %>

  更改Web.config中system.serviceModel节点如下:

 <system.serviceModel>
  <behaviors>
   <serviceBehaviors>
    <behavior name="Super.Wdxt.School.Hosting.UserBehavior">
     <serviceMetadata httpGetEnabled="true" />
     <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
  <services>
   <service behaviorConfiguration="Super.Wdxt.School.Hosting.UserBehavior"
    name="Super.Wdxt.School.Services.User">
    <endpoint address="" binding="wsHttpBinding" contract="Super.Wdxt.School.Contract.IUser">
     <identity>
      <dns value="localhost" />
     </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
   </service>
  </services>
 </system.serviceModel>

   4.Super.Wdxt.School.Web 中选择添加服务--点击发现

  

   确定。在Default后台页面使用如下:

            using (ServiceReference1.UserClient obj = new Super.Wdxt.School.Web.ServiceReference1.UserClient())
            {
                string aa = obj.GetName(1);

                Response.Write(aa);
            }
