创建一个简单的WCF程序

1、创建一个Service项目（ConsoleApplication)

我们建立一个简单的案例，做一个计算器，　假设我们只要求他做简单的加法运算就可以了。在Service项目中新建一个WCF服务，名称为Calculator。再修改里面的接口及实现方法。

 

ICalculator接口：

 1using System;
 2using System.Collections.Generic;
 3using System.Linq;
 4using System.Runtime.Serialization;
 5using System.ServiceModel;
 6using System.Text;
 7
 8namespace Service
 9{
    [ServiceContract]
    public interface ICalculator
    {
        [OperationContract]
        double Add(double a, double b);
    }
}

 

实现ICalculator的类CalculatorService：

 

 1using System;
 2using System.Collections.Generic;
 3using System.ServiceModel;
 4using System.Text;
 5
 6namespace Service
 7{
 8    [System.ServiceModel.ServiceBehavior(InstanceContextMode = System.ServiceModel.InstanceContextMode.Single, ConcurrencyMode = System.ServiceModel.ConcurrencyMode.Multiple)]
 9    public class CalculatorService : ICalculator
    {     

       double ICalculator.Add(double a, double b)
        {
            return a + b;
        }
    }
}

 

服务的配置文件：

 

 1<?xml version="1.0" encoding="utf-8" ?>
 2<configuration>
 3    <system.serviceModel>
 4        <behaviors>
 5            <serviceBehaviors>
 6                <behavior name="ServiceBehaviors">
 7                  <serviceDebug includeExceptionDetailInFaults="true" />
 8                </behavior>
 9            </serviceBehaviors>
        </behaviors>
      <bindings>
        <netTcpBinding>
          <binding name="TCPBinding" closeTimeout="1.00:00:00" openTimeout="1.00:00:00"
                   receiveTimeout="1.00:00:00" sendTimeout="1.00:00:00" maxBufferPoolSize="2147483647"
                   maxBufferSize="2147483647" maxConnections="2147483647" maxReceivedMessageSize="2147483647">
            <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
            <security mode="None">
              <message clientCredentialType="None" />
            </security>
          </binding>
        </netTcpBinding>
      </bindings>
        <services>
            <service behaviorConfiguration="ServiceBehaviors" name="Service.CalculatorService">
                <endpoint address="net.tcp://0.0.0.0:30000/CalculatorService"
                    binding="netTcpBinding" bindingConfiguration="TCPBinding"
                    name="TCP_Calculator" contract="Service.ICalculator" />
              <host>
                <timeouts closeTimeout="1.00:00:00" openTimeout="1.00:00:00" />
              </host>
            </service>
        </services>
    </system.serviceModel>
</configuration>

 

启动服务：

 

 1using System;
 2using System.Text;
 3using System.ServiceModel;
 4using System.ServiceModel.Channels;
 5
 6namespace Service
 7{
 8    class Program
 9    {
        static void Main(string[] args)
        {
            using (ServiceHost srv = new ServiceHost(new CalculatorService()))
            {
                srv.Open();

                Console.WriteLine("Started. Press any key to quit.");
                Console.ReadKey();
            }
        }
    }
}

 

新建一个Client项目（ConsoleApplication）

配置Endpoint

 

 1<?xml version="1.0" encoding="utf-8" ?>
 2<configuration>
 3    <system.serviceModel>                
 4        <bindings>
 5          <netTcpBinding>
 6            <binding name="TCPBinding" closeTimeout="1.00:00:00" openTimeout="1.00:00:00"
 7                receiveTimeout="1.00:00:00" sendTimeout="1.00:00:00" maxBufferPoolSize="2147483647"
 8                maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
 9              <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                  maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
              <security mode="None">
                <message clientCredentialType="None" />
              </security>
            </binding>
          </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://localhost:30000/CalculatorService"
                binding="netTcpBinding" bindingConfiguration="TCPBinding"
                contract="Service.ICalculator" name="Calculator" />
        </client>
    </system.serviceModel>
</configuration>

 

客户端代码：

 

using System;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Channels;
namespace Client
{
  Class Program
  {
     static void Main(string[] args)
    {            
        ChannelFactory<Service.ICalculator> factory=new ChannelFactory<Service.ICalculator>("Calculator");
        Service.ICalculator obj= factory.CreateChannel();
        double result= obj.Add(2, 3);
        Console.WriteLine(result.ToString());
        Console.ReadKey();
    }
  }
}
