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();
