服务三要素ABC  
A:Address 在哪里 （包含传输方式的信息）  
B:Binding 怎么实现（与地址的传输方式要匹配）  
C:Contract做什么（服务契约）

namespace WCFServiceDemo
    {
        [ServiceContract]
      public  interface IHelloService
        {
            [OperationContract]
            DateTime GetDateTime();
    
            [OperationContract]
            DataTable GetUserInfo();
        }
    }

继承接口

class HelloService:IHelloService
        {
           public DateTime GetDateTime()
           {
                return DateTime.Now;
           }
     
            public DataTable GetUserInfo()
            {
                string connstring = @"Data Source=WIN7U-20130122R\SQLEXPRESS;Initial Catalog=TCEKT;Persist Security Info=True;User ID=sa";
                SqlConnection conn = new SqlConnection(connstring);
                SqlDataAdapter sda=new SqlDataAdapter("select * from User",conn);
                DataTable dt = new DataTable();
                sda.Fill(dt);
                return dt;
            }
        }

Winfom调用

public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }
            ServiceHost host = null;
            private void button1_Click(object sender, EventArgs e)
            {
                host = new ServiceHost(typeof(WinformHello.HelloService));
                host.Open();
                label1.Text = "服务已启动！";
            }
        }

配置文件App.config

<?xml version="1.0" encoding="utf-8" ?>
    <configuration>
        <startup> 
            <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
        </startup>
        
        <system.serviceModel>
            <services>
                <service name="WinformHello.HelloService" behaviorConfiguration="testBehavior">
                    <host>
                        <baseAddresses>
                            <add baseAddress="http://localhost:8001/Hello"/>
                        </baseAddresses>
                    </host>
                    <endpoint address="" binding="basicHttpBinding" contract="WCFServiceDemo.IHelloService">
                    </endpoint> 
                </service> 
            </services>
            <behaviors>
                <serviceBehaviors>
                    <behavior name="testBehavior">
                        <serviceMetadata httpGetEnabled="true"/>
                    </behavior>
                </serviceBehaviors>
            </behaviors>
        </system.serviceModel>
    </configuration>

启动：

因win7安全性问题，如果启动不了 vs2012 右键

![05232416-a72ce972ac3840a59122f1355c6e6fbb.png][]

如果启动成功

在app.config文件中找到

Ctrl键+左击单击

OK  成功……
