WCF服务端的配置

　　一个最基本的服务（宿主）端配置如下：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name ="Keasy5.WCF.Imin.Chart06.Pro02.Service1"
               behaviorConfiguration="testBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:5555"/>
          </baseAddresses>
        </host>
        <endpoint address =""
                  binding="wsHttpBinding"
                  contract="Keasy5.WCF.Imin.Chart06.Pro02.IService1">
        </endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="testBehavior">
          <serviceMetadata  httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.ServiceModel;
using System.Text;
using System.Windows.Forms;
using Keasy5.WCF.Imin.Chart06.Pro02;

namespace Keasy5.WCF.Chart06.Pro02.Host
{
    public partial class Form1 : Form
    {
        private ServiceHost serviceHost = new ServiceHost(typeof(Service1));

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            ServiceHost serviceHost = new ServiceHost(typeof(Service1));
            serviceHost.Open();
            this.label1.Text = "服务器已开启！";
        }

        private void button2_Click(object sender, EventArgs e)
        {
            if (serviceHost.State != CommunicationState.Closed)
            {
                serviceHost.Close();
                this.label1.Text = "服务已关闭！";
            }
        }
    }
}

　　宿主选择WinForm，服务的开启和关闭如下代码所示：

　　其中创建宿主的ServiceHost类的构造函数：

        //
        // 摘要: 
        //     使用服务的类型及其指定的基址初始化 System.ServiceModel.ServiceHost 类的新实例。
        //
        // 参数: 
        //   serviceType:
        //     承载服务的类型。
        //
        //   baseAddresses:
        //     System.Uri 类型的数组，包含承载服务的基址。
        //
        // 异常: 
        //   System.ArgumentNullException:
        //     serviceType 为 null。
        public ServiceHost(Type serviceType, params Uri[] baseAddresses);

第二个参数是可变参数类型：所以可以参入基于不同协议的Uri，

Uri = “net.TCP：//localhost/....”

Uri = "http://....."

Uri = "net.pipe：//。。。"

。。。。

传入这些Uir基地址，实现同一服务，可同时提供多种协议的服务：

            //地址
            Uri pipeaddress = new Uri("net.pipe://localhost/NetNamedPipeBinding");
            Uri tcpaddress = new Uri("net.tcp://localhost:8088/TcpBinding");

            //服务宿主对象
            host = new ServiceHost(typeof(WcfServiceLibrary1.Service1), pipeaddress, tcpaddress);

            //绑定
            NetNamedPipeBinding pb = new NetNamedPipeBinding();
            NetTcpBinding tp = new NetTcpBinding();

或者使用配置文件进行配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="WcfServiceLibrary1.Service1" behaviorConfiguration="textBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:8088/tcpBinding"/>
            <add baseAddress="http://localhost:3200/httpBinding"/>
            <add baseAddress="net.pipe://localhost/pipeBinding"/>
          </baseAddresses>
        </host>
        <endpoint address="tcpmex" binding="mexTcpBinding" contract="IMetaExchange"></endpoint>
        <endpoint address="pipemex" binding="mexNamedPipeBinding" contract="IMetaExchange"></endpoint>

        <endpoint address="" binding="wsHttpBinding" contract="WcfServiceLibrary1.IService1"></endpoint>
        <endpoint address="" binding="netTcpBinding" contract="WcfServiceLibrary1.IService1"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="textBehavior">
          <serviceMetadata/>
          <serviceDebug/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

客户端调用WCF服务

客户端调用WCF服务，需要一个WCF服务的代理类;

获取该代理类的方法有几种：

【1】在客户端的项目中引用服务的方式　　　　

　　　　添加服务引用时自动生成的服务代理时自动生成的EndPiont

          <!--添加服务引用时自动生成的服务代理时自动生成的EndPiont-->
          <endpoint address="http://127.0.0.1:9999/Easy5WCFService" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_CalcutorService" contract="CalcutorWCFService.CalcutorService"
                name="BasicHttpBinding_CalcutorService" />

            //方法1：使用添加服务引用时自动生成的服务代理（这时，自动生成app.config）
            //此法用的代理服务命名空间的类型
            using (CalcutorWCFService.CalcutorServiceClient proxy = new CalcutorWCFService.CalcutorServiceClient())
            {
                double x  = Convert.ToDouble(this.textBox1.Text);
                double y = Convert.ToDouble(this.textBox2.Text);

                this.textBox3.Text = Convert.ToString(proxy.Add(x, y));
            }

【2】手工生成代理类，这种又有很多种方式：

　　　　2.1　 ChannelFactory<T>

　　使用ChannelFactory<T>的好处是支持泛型。

            //此法需要：自己动手添加app.config
            using (ChannelFactory<Contract.ICalcuator> channelFactory = new ChannelFactory<Contract.ICalcuator>("calcutorService"))//calcutorService为配置文件（app.config）中的endpoint的Name属性
            {
                Contract.ICalcuator calcuator = channelFactory.CreateChannel();

                double x = Convert.ToDouble(this.textBox1.Text);
                double y = Convert.ToDouble(this.textBox2.Text);

                this.textBox3.Text = Convert.ToString(calcuator.Add(x, y));
            }

　　　　需要手工在app.config文件中添加endPoint节点配置：

          <!--自己动手写服务代理时,需要手动添加的EndPoint-->
          <endpoint address="http://127.0.0.1:9999/Easy5WCFService" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_CalcutorService" contract="Contract.ICalcuator"
                name="calcutorService" />

ChannelFactory<T>的构造函数有多个重载，也可以按如下方式创建：

            using (ChannelFactory<Contract.ICalcuator> channelFactory = new ChannelFactory<Contract.ICalcuator>(new BasicHttpBinding(), "http://127.0.0.1:9999/Easy5WCFService"))
            {
                Contract.ICalcuator calcuator = channelFactory.CreateChannel();

                double x = Convert.ToDouble(this.textBox1.Text);
                double y = Convert.ToDouble(this.textBox2.Text);

                this.textBox3.Text = Convert.ToString(calcuator.Add(x, y));
            }

　　但是，这种方式是硬编码方式，灵活性不好，不推荐。

　　 2.2 使用svcutil.exe工具生成代理类：

　　　　　WCF的服务元数据（Metadata），遵循Web服务描述语言（WSDL）标准，所以支持多种编程语言，处理WCF的svcutil.exe外，

java程序员也可以使用诸如WSDL2Java工具生成Java语言的客户端代理类。

下面介绍使用svcutil.exe生成C#语言的代理类：

第一步：公开WCF服务的元数据信息

　　　　　　　方法一：　通过<serviceMetadata httpGetEnabled="true"/>公开，如下所示

  <system.serviceModel>
    <services>
      <service name ="Keasy5.WCF.Imin.Chart06.Pro02.Service1"
               behaviorConfiguration="testBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:5555"/>
          </baseAddresses>
        </host>
        <endpoint address =""
                  binding="wsHttpBinding"
                  contract="Keasy5.WCF.Imin.Chart06.Pro02.IService1">
        </endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="testBehavior">
          <serviceMetadata  httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

　　　　　　　　方法二：　通过EndPoint端点的方式进行公开，在服务的配置文件中添加如下配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name ="Keasy5.WCF.Imin.Chart06.Pro02.Service1"
               behaviorConfiguration="testBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:5555"/>
          </baseAddresses>
        </host>
        <endpoint address =""
                  binding="wsHttpBinding"
                  contract="Keasy5.WCF.Imin.Chart06.Pro02.IService1">
        </endpoint>

        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetatadaExchange">
        </endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="testBehavior">
          <serviceMetadata  httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

　　　　　　　　公开WCF服务的元数据信息后就可以在浏览器中输入：http://localhost:5555 就可以查看WCF服务信息。

第二步：

　　　　　　　　打开【VS2013 开发人员命令提】，输入：

　　　　　　　　　　　　svcutil.exe http://localhost:5555/?wsdl

现在用在项目中引用服务的方式添加代理,客户端如下调用代理：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Keasy5.WCF.Chart06.Pro02.Client.ServiceReference1;
using Keasy5.WCF.Imin.Chart06.DTO;

namespace Keasy5.WCF.Chart06.Pro02.Client
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            IService1 proxService1 = new Service1Client();
            Employee newEmployee = new Employee()
            {
                Name = "Jack",
                Job = "Killer",
                Salary = 1000000,
                Dept = "N/A"
            };

            proxService1.AddEmployee(newEmployee);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            IService1 proxService1 = new Service1Client();

            IEnumerable<Employee> employees = proxService1.GetEmployees();
            this.dataGridView1.DataSource = employees;
        }
    }
}
