超简单WCF例子

项目图如下：

using System;
using System.ServiceModel;

namespace ServiceLib
{
    [ServiceContract]
    public interface ICalcService
    {
        /// <summary>
        /// 欢迎方法
        /// </summary>
        /// <param name="name"></param>
        /// <returns></returns>
        [OperationContract]
        String WelCome(String name);
    }
}

using System;

namespace ServiceLib
{
    public class CalcService:ICalcService
    {
        /// <summary>
        /// 欢迎
        /// </summary>
        /// <param name="name"></param>
        /// <returns></returns>
        public string WelCome(string name)
        {
            Console.WriteLine(name);
            return "你好：" + name;
        }
    }
}

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

using ServiceLib;

namespace CalcHost
{
    class Program
    {
        static void Main(string[] args)
        {
            // 指定契约
            Uri address = new Uri("http://127.0.0.1:8888");
            ServiceHost host = new ServiceHost(typeof(CalcService),address);
            host.AddServiceEndpoint(typeof(ICalcService), new WSHttpBinding(), "Calc");

            // 公开元数据    注：这个上线前关掉应该比较好
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            host.Description.Behaviors.Add(smb);

            // 开启服务
            host.Opened += (a, b) => Console.WriteLine("服务已开启");
            host.Open();
            Console.Read();
        }
    }
}

using Client.ServiceReference;
using System;

namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            using (CalcServiceClient service = new CalcServiceClient())
            {
                Console.WriteLine("Please input name:");
                String name = Console.ReadLine();
                Console.WriteLine(service.WelCome(name));
                Console.Read();
            }
        }
    }
}
