不用配置文件的wcf实例

1、根据需求建立一个类库，这里命名为ComputeServe

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;namespace ComputeServe{    [ServiceContract]    public interface ICompute    {       [OperationContract]        double AddData(double x, double y);    }}

上面需要添加引用System.ServiceModel

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ComputeServe{    public class Compute : ICompute    {        public double AddData(double x, double y)        {            return x + y;        }    }}

将类库生成dll

2、建立服务端

添加刚生成的dll和System.ServiceModel

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using System.ServiceModel.Description;namespace wcf1{    class Program    {        static void Main(string[] args)        {            using (ServiceHost host = new ServiceHost(typeof(ComputeServe.Compute)))            {                //定义绑定                System.ServiceModel.Channels.Binding httpBinding = new BasicHttpBinding();                //定义终结点                host.AddServiceEndpoint(typeof(ComputeServe.ICompute), httpBinding, "http://localhost:8001/");//所以服务端的URI也应该用这个                if (host.Description.Behaviors.Find<System.ServiceModel.Description.ServiceMetadataBehavior>() == null)                {                    host.Opened += delegate                    {                        Console.WriteLine("Service is already open");                    };                    //运行                    host.Open();                    Console.ReadKey();                    //关闭                    host.Close();                }            }        }    }}

3、客户端

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;namespace ComputeClient{    [ServiceContract]    interface ICompute    {        [OperationContract]        double AddData(double x, double y);    }}

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;namespace ComputeClient{    class Compute:System.ServiceModel.ClientBase<ICompute>,ICompute    {        public double AddData(double x, double y)        {            return base.Channel.AddData(x, y);        }    }}

注：取名ICompute，Compute这个是因为dll里面是这样命名的

调用

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using System.ServiceModel.Channels;using System.ServiceModel.Description;namespace ComputeClient{    class Program    {        static void Main(string[] args)        {            string address = "http://localhost:8001/";            ChannelFactory<ICompute> channel =                new ChannelFactory<ICompute>(                    new BasicHttpBinding(),                    new EndpointAddress(                        new Uri(address)));            ICompute proxy = channel.CreateChannel();            Console.WriteLine("WCF调用结果为：{0}", proxy.AddData(2, 3));            Console.ReadKey();        }    }}
