服务端

 

1.创建一个空的解决方案:WCFDemo:

 

2.创建一个宿主控制台程序：Host

 

3.右击Host项目，选择“添加”--“新建项”，选择“WCF服务”创建名为“Service1.cs”的服务

 

 

如此：VS2010已经为我们创建了 IService1.cs   Service1.cs   app.config  三个文件，其中IService1.cs和Service1.cs 创建了同属于Host命名空间的类，我们可以修改这三个文件：

 

IService1.cs ：

using System.ServiceModel;

namespace Host

{

    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。

    [ServiceContract]

    public interface IService1

    {

        [OperationContract]

        string DoWork(int value);

    }

}

 

Service1.cs：

using System.ServiceModel;

namespace Host

{

    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的类名“Service1”。

    public class Service1 : IService1

    {

        public string  DoWork(int value)

        {

            int iPingfang = value * value;

            return string.Format("经过平方后的值为：{0}",iPingfang );

        }

    }

}

 

App.config：

文件原则上可以不用改，但是address太长了（默认的为baseAddress=""）缩短为baseAddress=“”

 

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

    <system.serviceModel>

        <behaviors>

            <serviceBehaviors>

                <behavior name="">

                    <serviceMetadata httpGetEnabled="true" />

                    <serviceDebug includeExceptionDetailInFaults="false" />

                </behavior>

            </serviceBehaviors>

        </behaviors>

        <services>

            <service name="Host.Service1">

                <endpoint address="" binding="wsHttpBinding" contract="Host.IService1">

                    <identity>

                        <dns value="localhost" />

                    </identity>

                </endpoint>

                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

                <host>

                    <baseAddresses>

                        <add baseAddress="" />

                    </baseAddresses>

                </host>

            </service>

        </services>

    </system.serviceModel>

</configuration>

 

 

 

4.此外WCF服务必须在宿主进程中运行，我们可以修改 Program.cs 文件，创建宿主进程：

using System.ServiceModel;

namespace Host

{

    class Program

    {

        static void Main(string[] args)

        {

            using (ServiceHost host = new ServiceHost(typeof(Host.Service1)))

            {

                host.Open();

                Console.WriteLine("服务已经启动......");

                Console.ReadLine();

                host.Close();

            }

        }

    }

}

 

 

 

5.编译运行程序，生成Host.exe文件

 

 

 

---

 客户端

 

1.启动刚创建的WCF服务宿主进程Host.exe

 

 

2.创建一个客户端控制台程序:Client

 

3.右击“引用”--“添加服务引用”，在“地址”的TextBox里面输入服务器的地址（就是咱们前面设置的baseaddress地址），并点击“前往”将得到目标服务器上面的Services，如下图所示：

 

 

 

 

如此,这一步将在客户端间接借助SvcUtil.exe文件创建客户端代理（命名空间为：using Client.ServiceReference1;）以及配置文件app.config,具体如下：

 

app.config:

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

    <system.serviceModel>

        <bindings>

            <wsHttpBinding>

                <binding name="WSHttpBinding_IService1" closeTimeout="00:01:00"

                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

                    bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"

                    maxBufferPoolSize="524288" maxReceivedMessageSize="65536"

                    messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"

                    allowCookies="false">

                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"

                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />

                    <reliableSession ordered="true" inactivityTimeout="00:10:00"

                        enabled="false" />

                    <security mode="Message">

                        <transport clientCredentialType="Windows" proxyCredentialType="None"

                            realm="" />

                        <message clientCredentialType="Windows" negotiateServiceCredential="true"

                            algorithmSuite="Default" />

                    </security>

                </binding>

            </wsHttpBinding>

        </bindings>

        <client>

            <endpoint address="" binding="wsHttpBinding"

                bindingConfiguration="WSHttpBinding_IService1" contract="ServiceReference1.IService1"

                name="WSHttpBinding_IService1">

                <identity>

                    <dns value="localhost" />

                </identity>

            </endpoint>

        </client>

    </system.serviceModel>

</configuration>

 

 

4.修改客户端程序 Program.cs ，并使用代理访问服务契约：

using System.ServiceModel;

using Client.ServiceReference1;//引用命名空间

namespace Client

{

    class Program

    {

        static void Main(string[] args)

        {

            ServiceReference1.Service1Client proxy = new Service1Client();

            string str = proxy.DoWork(2);//运行服务端方法

            Console.WriteLine(str);

            Console.ReadLine();

        }

    }

}

 

 

5.编译运行程序，生成 Client.exe
