WCF简单实例

 

一 简单示例结构

 [此实例纯手动实现，更简单地可以使用WCF的工程向导来创建wcf service，WCF Service也可以使用config文件，可以使用project的add referece来自动生成proxy和config]

 

二 WCFServer

1) wcfserver.cs文件如下：（需要引用system.servicemodel assembly）

using System;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace Microsoft.ServiceModel.Samples
{
     //  Define a service contract.
     [ ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples") ]
     public  interface ICalculator
    {
         [ OperationContract ]
         double   Add ( double  n1,  double  n2);
         [ OperationContract ]
         double  Subtract( double  n1,  double  n2);
         [ OperationContract ]
         double  Multiply( double  n1,  double  n2);
         [ OperationContract ]
         double  Divide( double  n1,  double  n2);
    }

     //  Service class that implements the service contract.
     //  Added code  to  write output  to  the console window.
     public  class CalculatorService : ICalculator
    {
         public   double   Add ( double  n1,  double  n2)
        {
             double  result  =  n1  +  n2;
            Console.WriteLine("Received  Add ({ 0 },{ 1 })", n1, n2);
            Console.WriteLine(" Return : { 0 }", result);
             return  result;
        }
         public   double  Subtract( double  n1,  double  n2)
        {
             double  result  =  n1  -  n2;
            Console.WriteLine("Received Subtract({ 0 },{ 1 })", n1, n2);
            Console.WriteLine(" Return : { 0 }", result);
             return  result;
        }
         public   double  Multiply( double  n1,  double  n2)
        {
             double  result  =  n1  *  n2;
            Console.WriteLine("Received Multiply({ 0 },{ 1 })", n1, n2);
            Console.WriteLine(" Return : { 0 }", result);
             return  result;
        }
         public   double  Divide( double  n1,  double  n2)
        {
             double  result  =  n1  /  n2;
            Console.WriteLine("Received Divide({ 0 },{ 1 })", n1, n2);
            Console.WriteLine(" Return : { 0 }", result);
             return  result;
        }
    }

    class WCFServer
    {
        static void Main(string []  args)
        {
             //  Step  1   of  the address configuration  procedure : 

            // Create  a URI  to  serve  as  the base address.
            Uri baseAddress  =  new Uri("http: // localhost: 8000 / ServiceModelSamples / Service");

             //  Step  2   of  the hosting  procedure :  Create  ServiceHost
            ServiceHost selfHost  =  new ServiceHost(typeof(CalculatorService), baseAddress);

            try
            {
                 //  Step  3   of  the hosting  procedure :  Add  a service endpoint.
                selfHost.AddServiceEndpoint(
                    typeof(ICalculator),
                    new WSHttpBinding(),
                    "CalculatorService");

                 //  Step  4   of  the hosting  procedure : Enable metadata exchange.
                ServiceMetadataBehavior smb  =  new ServiceMetadataBehavior();
                smb.HttpGetEnabled  =  true;
                selfHost.Description.Behaviors. Add (smb);

                 //  Step  5   of  the hosting  procedure : Start ( and   then  stop) the service.
                selfHost. Open ();
                Console.WriteLine("The service  is  ready.");
                Console.WriteLine("Press  < ENTER >   to  terminate service.");
                Console.WriteLine();
                Console.ReadLine();

                 //   Close  the ServiceHostBase  to   shutdown  the service.
                selfHost. Close ();
            }
            catch (CommunicationException ce)
            {
                Console.WriteLine("An exception occurred: { 0 }", ce.Message);
                selfHost.Abort();
            }
        }
    }
}

2) 运行wcfserver后，在浏览器中查看wcfserver提供的wcf service如下：（此时scfserver必须处于运行状态）

 

三 WCFClient （控制台程序）

1) 使用svcutil.exe生成wcfserver提供的wcf service的代理和wcfclient需要的config文件，如下：（此时scfserver必须处于运行状态）

" C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\svcutil.exe "   / language :cs   / out :WCFClient \ generatedProxy . cs  / config :WCFClient \ app . config http: // localhost: 8000 / ServiceModelSamples / service

2）将生成的generatedproxy.cs和app.config加入wcfclient工程中，

generatedproxy.cs如下：

     public   double  Add( double  n1,  double  n2)
    {

     public   double  Divide( double  n1,  double  n2)
    {

    }
}

app.config如下：

3）wcfclient.cs文件如下： 

using  System;
using  System.ServiceModel;

namespace  Microsoft.ServiceModel.Samples
{

     class  WCFClient
    {
         static   void  Main()
        {
             // Step 1: Create an endpoint address and an instance of the WCF Client.
            CalculatorClient client  =   new  CalculatorClient();


             //  Step 2: Call the service operations.
             //  Call the Add service operation.
             double  value1  =   100.00D ;
             double  value2  =   15.99D ;
             double  result  =  client.Add(value1, value2);
            Console.WriteLine( " Add({0},{1}) = {2} " , value1, value2, result);

             //  Call the Subtract service operation.
            value1  =   145.00D ;
            value2  =   76.54D ;
            result  =  client.Subtract(value1, value2);
            Console.WriteLine( " Subtract({0},{1}) = {2} " , value1, value2, result);

             //  Call the Multiply service operation.
            value1  =   9.00D ;
            value2  =   81.25D ;
            result  =  client.Multiply(value1, value2);
            Console.WriteLine( " Multiply({0},{1}) = {2} " , value1, value2, result);

             //  Call the Divide service operation.
            value1  =   22.00D ;
            value2  =   7.00D ;
            result  =  client.Divide(value1, value2);
            Console.WriteLine( " Divide({0},{1}) = {2} " , value1, value2, result);

             // Step 3: Closing the client gracefully closes the connection and cleans up resources.
            client.Close();


            Console.WriteLine();
            Console.WriteLine( " Press <ENTER> to terminate client. " );
            Console.ReadLine();

        }
    }
}

 

4）运行wcfserver后如下：
