WCF的简单实例（手写代码实现）--服务端

1、引用：

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

2、申明接口

///这是接口

[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
public interface MyJK
{
[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);

}

3、实现接口

    //实现契约和接口
    public class AABB : MyJK
    {
        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;
        }
    }

4、定义服务、启动服务

         Uri baseAddress = new Uri("http://localhost:8989/aaa/");    //随便写
         ServiceHost serviceHost = new ServiceHost(typeof(AABB), baseAddress);

         serviceHost.AddServiceEndpoint(typeof(MyJK), new WSHttpBinding(), "BBCCDD");
         ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
         smb.HttpGetEnabled = true;
         serviceHost.Description.Behaviors.Add(smb);

         serviceHost.Open();
