1.简单的WCF模型

1.结构

2.契约：

 

using System.ServiceModel;
using Rhythmk.Entity;
namespace Rhythmk.Contracts
{
    [ServiceContract(Namespace="http://wwww.wangkun.com")]
  
    publicinterface ICalculate
    {
        [OperationContract(Name="AddServices")]
        double Add(double x, double y);

        /*
         Name :则体现在客户端调用此方法时候 显示的真实方法名
         IsOneway:这意味着客户端仅仅是向服务端发送一个运算的请求
                 并不会通过回复消息得到任何运算结果。
         
         */
        [OperationContract(Name ="AddStrServices")]
        string Add(string x, string y);
       

    }
}

3. 服务

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

using Rhythmk.Contracts;
using Rhythmk.Entity;
using System.ServiceModel;
using System.ServiceModel.Activation;

namespace Rhythmk.Services
{
    ///<summary>
    /// 计算器
    ///</summary>
    ///
/*
     通过
     ADO.NET 数据服务[.svc] 建立服务宿主的时候 需要引用
     *using System.ServiceModel.Activation;
     *同时在服务类前面需要配置 
     [AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Required)]
     */
    [AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Required)]
    publicclass Calculate:ICalculate
    {
        publicdouble Add(double x, double y) 
        {

            return x + y;
        }

        publicstring Add(string x, string y)
        {
            return"Result"+ x + y;
        }

    }
}

4.控制台进行寄宿

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="metaBehavior">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Rhythmk.Services.Calculate" behaviorConfiguration="metaBehavior">
        <endpoint address="" 
            binding="basicHttpBinding" bindingConfiguration="" contract="Rhythmk.Contracts.ICalculate">
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://127.0.0.1:1234/Rhythmk.Services.Calculate"/>
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
</configuration>

代码:

代码:
using System;
using System.ServiceModel;

using Rhythmk.Services;

namespace Rhythmk.ConsoleApp
{
    class Program
    {
        staticvoid Main(string[] args)
        {
            CreateCalculateService();
        }
        staticvoid CreateCalculateService() 
        {
            Console.WriteLine("----------CreateCalculateService---Star---------");
            using (ServiceHost host =new ServiceHost(typeof(Calculate))) 
            {
                host.Opened +=delegate { Console.WriteLine("CalculateService已经启动，按任意键终止服务！"); };
                host.Open();
                Console.Read();
            }
          
        }
    }
}

5.ADO.NET 数据服务[.svc] 建立服务宿主

Rhythmk.WebHostMonitor\Calculate\Calculate.svc

<%@ ServiceHost Language="C#"  Debug="true" Service="Rhythmk.Services.Calculate" %>

6.客户端调用

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
  <client>
    <endpoint address="http://wcf.wangkun.w/Calculate/Calculate.svc"
        binding="basicHttpBinding"  contract="Rhythmk.Contracts.ICalculate"
        name="CalculateEndPoint">
    </endpoint>
  </client>
</system.serviceModel>
</configuration>

代码：

using Rhythmk.Contracts;
using System.ServiceModel;
using System.Web.Services;

 ChannelFactory<ICalculate> calculatorChannelFactory =new ChannelFactory<ICalculate>("CalculateEndPoint");
 ICalculate proxy = calculatorChannelFactory.CreateChannel();
  Utitl.Alert(proxy.Add(10, 20).ToString());
