WCF笔记：ServiceContract继承

主机：

 

using System;
using System.ServiceModel;

namespace InheritanceDemo
{
   [ServiceContract]
   interface ISimpleCalculator
   {
      [OperationContract]
      int Add(int arg1,int arg2);
   }

   [ServiceContract]
   interface IScientificCalculator : ISimpleCalculator
   {
      [OperationContract]
      int Multiply(int arg1,int arg2);
   }

   class MyCalculator : IScientificCalculator
   {
      public int Add(int arg1,int arg2)
      {
         return arg1 + arg2;
      }
      public int Multiply(int arg1,int arg2)
      {
         return arg1 * arg2;
      }
   }
}

 

主机控制台：

 

using System;
using System.ServiceModel;

namespace InheritanceDemo
{
   class Program
   {
      public static void Main()
      {
         ServiceHost serviceHost = new ServiceHost(typeof(MyCalculator),new Uri("http://localhost:8000/"));
         serviceHost.Open();

         Console.WriteLine("Press ENTER to shut down service.");
         Console.ReadLine();
        
         serviceHost.Close();
      }
   }
}

 

客户端：

 

using System.ServiceModel;

[ServiceContract]
public interface ISimpleCalculator
{
   [OperationContract]
   int Add(int arg1,int arg2);
}

//局部类
public partial class SimpleCalculatorClient : ClientBase<ISimpleCalculator>,ISimpleCalculator
{
   public SimpleCalculatorClient()
   {}

   public SimpleCalculatorClient(string endpointConfigurationNamee) : base(endpointConfigurationNamee)
   {}

   public int Add(int arg1,int arg2)
   {
       return this.Channel.Add(arg1, arg2);
   }
}

 

 

 

using System.ServiceModel;

[ServiceContract]
public interface IScientificCalculator : ISimpleCalculator
{
    [OperationContract]
    int Multiply(int arg1,int arg2);
}

public partial class ScientificCalculatorClient : ClientBase<IScientificCalculator>,IScientificCalculator
{
   public ScientificCalculatorClient()
   {}

   public ScientificCalculatorClient(string endpointConfigurationName) : base(endpointConfigurationName)
   {}

   public int Add(int arg1,int arg2)
   {
      return Channel.Add(arg1,arg2);
   }

   public int Multiply(int arg1,int arg2)
   {
      return Channel.Multiply(arg1,arg2);
   }
}

 

调用：

 

using System;
using System.ServiceModel;

namespace InheritanceDemo
{
   class MyClient
   {
      static void Main(string[] args)
      {
         int result;

         SimpleCalculatorClient proxy1 = new SimpleCalculatorClient();

         result = proxy1.Add(1,2);

         Console.WriteLine("1 + 2 = " + result);

         proxy1.Close();

         ScientificCalculatorClient proxy2 = new ScientificCalculatorClient();
        
         result = proxy2.Add(3,4);
         Console.WriteLine("3 + 4 = " + result);
        
         result = proxy2.Multiply(5,6);
         Console.WriteLine("5 * 6 = " + result);
        
         proxy2.Close();

         Console.ReadLine();        
      }
   }
}
