买了《WCF技术剖析》,按着书本的例子进行操作,写下我的操作过程。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace xuwei.WcfServices.Contracts//服务契约
{
[ServiceContract(Name="CalculatorService",Namespace="http://blog.csdn.net/xw13106209")]//将接口定义成服务契约
public interface ICalculator
{
[OperationContract]
double Add(double x,double y);
double Subtract(double x,double y);
double Multiply(double x,double y);
double Divide(double x, double y);
}
}
using xuwei.WcfServices.Contracts;
namespace xuwei.WcfServices.Services//实现服务契约
public class CalculatorService:ICalculator
public double Add(double x,double y)
{
return x + y;
}
public double Subtract(double x, double y)
return x - y;
public double Multiply(double x, double y)
return x * y;
public double Divide(double x, double y)
return x / y;
using xuwei.WcfServices.Services;
using System.ServiceModel.Description;
namespace xuwei.WcfServices.Hosting//自主服务寄宿
class Program
static void Main(string[] args)
using (ServiceHost host=new ServiceHost(typeof(CalculatorService)))
{
host.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "http://127.0.0.1:9999/calculatorservice");
if (host.Description.Behaviors.Find<ServiceMetadataBehavior>() == null)
{
ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
behavior.HttpGetEnabled = true;
behavior.HttpGetUrl = new Uri("http://127.0.0.1:9999/calculatorservice/metadata");
host.Description.Behaviors.Add(behavior);
}
host.Opened += delegate
Console.WriteLine("CalculatorService已经启动,按任意键终止服务!");
};
host.Open();
Console.Read();
}
完成以后需要编译Hosting下的program.cs。但是在通过Ctrl+F5执行(其实可以通过右键解决方案->生成解决方案完成,不需要通过Ctrl+F5执行)的时候可能报错:
无法直接启动带有“类库输出类型”的项目,如下图所示。
这时我们需要右键Hosting,然后选择“设为启动项目”,再次执行就不会报错了。
在进行真正的WCF应用开发时,一般不会直接通过编码的方式进行终结点的添加和服务行为的定义,而是通过配置的方式进行。上面添加终结点和定义服务行为的代码可以通过如下方法进行。首先在Hosting项目中创建应用程序配置文件App.config,在App.config中添加如下配置:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="metadataBehavior">
<serviceMetadata httpGetEnabled="true" httpGetUrl="http://127.0.0.1:9999/calculatorservice/metadata" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="metadataBehavior" name="xuwei.WcfServices.Services.CalculatorService">
<endpoint address="http://127.0.0.1:9999/calculatorservice" binding="wsHttpBinding" contract="xuwei.WcfServices.Contracts.ICalculator" />
</service>
</services>
</system.serviceModel>
</configuration>
如果采用了上诉的配置,服务寄宿代码将会得到极大的精简,只需包含下面几行代码:
//host.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "http://127.0.0.1:9999/calculatorservice");
//if (host.Description.Behaviors.Find<ServiceMetadataBehavior>() == null)
//{
// ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
// behavior.HttpGetEnabled = true;
// behavior.HttpGetUrl = new Uri("http://127.0.0.1:9999/calculatorservice/metadata");
// host.Description.Behaviors.Add(behavior);
//}
using xuwei.WcfService.Client.CalculatorServices;
namespace xuwei.WcfService.Client
using (CalculatorServiceClient proxy = new CalculatorServiceClient())
Console.WriteLine("x+y={2} when x={0} and y={1}",1,2,proxy.Add(1,2));
Console.WriteLine("x-y={2} when x={0} and y={1}", 1, 2, proxy.Subtract(1, 2));
Console.WriteLine("x*y={2} when x={0} and y={1}", 1, 2, proxy.Multiply(1, 2));
Console.WriteLine("x/y={2} when x={0} and y={1}", 1, 2, proxy.Divide(1, 2));
在执行步骤四以后E:/ms_workplace/WCF1/Hosting/bin/Debug目录下会有一个“Hosting.exe”的应用程序,双击打开该应用程序:
然后右键Client项目,选择“添加服务引用”
点击确定即可完成服务引用的添加,这时Client下就会多出一个Service Reference
双击CalculatorServices,在对象浏览器中能够看到如下视图
编译Client,会在E:/ms_workplace/WCF1/Client/bin/Debug有Client.exe,双击打开这个应用程序,会有如下结果:
