Question

如何从客户端控制台应用程序在hostconsole应用程序中使用wcf服务。这是wcf服务：

namespace HostConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            using (System.ServiceModel.ServiceHost host = new System.ServiceModel.ServiceHost(typeof(FirstWcfService.Service)))
            {
                host.Open();
                Console.WriteLine("Sai");
                Console.ReadLine();
            }
        }
    }
}

天空，再次感谢你。你已经读懂了我的想法。

但是我遇到了一个问题：

以下是我为主机和客户端修改上述代码的方法：

主持人

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace ConsoleApplication1
{
    class Program
    {

        private static void Main(string[] args)
        {
            const string endpointAddress = "net.tcp://localhost:8001/Service";

            var baseAddress = new Uri(endpointAddress);

            using (var host = new ServiceHost(typeof(FirstWcfService.Service), baseAddress))
            {
                host.AddServiceEndpoint(typeof(FirstWcfService.IService), new NetTcpBinding(), baseAddress);
                host.Open();

            }

            Console.WriteLine("Sai");
            Console.ReadLine();
        }

    }
}

客户

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

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

namespace ConsoleApplication2
{
    class Program
    {
        private static void Main(string[] args)
        {
            const string endpointAddress = "net.tcp://localhost:8001/Service";


                // this is the client code.. simply put this in another console app
                using (var factory = new ChannelFactory<FirstWcfService.IService>(new NetTcpBinding(), endpointAddress))
                {
                    FirstWcfService.IService channel = factory.CreateChannel();

                    //DateTime d = channel.GetDate();
                    string h = channel.Hello();

                    //Console.WriteLine(String.Format("It is {0}", d));
                    Console.WriteLine(String.Format("It is {0}", h));
                }
                //// end client code

        }


    }
}

主机运行正常，当客户端在这里运行是我得到的例外：

无法连接到net.tcp：// localhost：8001 / Service。连接尝试持续时间跨度为00：00：00.8899011。 TCP错误代码10061：无法建立连接，因为目标计算机主动拒绝它127.0.0.1:8001。

如果您有任何建议，请与我们联系。谢谢 Ñ

最简单的实现，不知道细节...并且有一些关于错误处理和处理错误的问题，但这应该让你去....

您需要确保为服务实现了一个接口，并确保服务和客户端之间的绑定和地址匹配。

注意：我使用net.tcp有几个原因.1）我知道它符合激励这个问题的要求2）它消除了处理2008年/ vista / 7上托管http服务的很多陷阱

using System;
using System.ServiceModel;

namespace ConsoleApplication1
{

    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        DateTime GetDate();
    }


    public class ServiceImplementer : IService
    {
        #region IService Members

        public DateTime GetDate()
        {
            return DateTime.Now;
        }

        #endregion
    }



    internal class Program
    {
        private static void Main(string[] args)
        {
            const string endpointAddress = "net.tcp://localhost:8001/Service";

            var baseAddress = new Uri(endpointAddress);

            using (var host = new ServiceHost(typeof (ServiceImplementer), baseAddress))
            {
                host.AddServiceEndpoint(typeof (IService), new NetTcpBinding(), baseAddress);
                host.Open();



                // this is the client code.. simply put this in another console app
                using (var factory = new ChannelFactory<IService>(new NetTcpBinding(), endpointAddress))
                {
                    IService channel = factory.CreateChannel();

                    DateTime d = channel.GetDate();

                    Console.WriteLine(String.Format("It is {0}", d));
                }
                // end client code

            }

            Console.WriteLine("Sai");
            Console.ReadLine();
        }
    }
}
