WCF类库

契约IUser1，实现User1

[ServiceContract]
    public interface IUser1
    {
        [OperationContract]
        string GetUser1Name(string name);
    }

    public class User1 : IUser1
    {
        public string GetUser1Name(string name)
        {
            return "我是usre1" + name;
        }
    }

契约IUser2 ，实现User2

    [ServiceContract]
    public interface IUser2
    {
        [OperationContract]
        string GetUser1Name(string name);
    }

    public class User2 : IUser2
    {
        public string GetUser1Name(string name)
        {
            return "我是user2" + name;
        }
    }

契约IUnity1和IUnity2，实现Unity（一个实现继承了两个契约，主意看一下配置文件如何配置）

    [ServiceContract]
    public interface IUnity1
    {
        [OperationContract]
        int GetUnityCount();
    }

    [ServiceContract]
    public interface IUnity2
    {
        [OperationContract]
        string GetUnityString();
    }

    public class Unity : IUnity1, IUnity2
    {
        public int GetUnityCount()
        {
            return ;
        }

        public string GetUnityString()
        {
            return "Unity";
        }
    }

宿主

        static void Main(string[] args)
        {
            ServiceHost sh1 = new ServiceHost(typeof(WcfLib.User1));
            sh1.Open();
            Console.WriteLine("服务1开启");
            ServiceHost sh2 = new ServiceHost(typeof(WcfLib.User2));
            sh2.Open();
            Console.WriteLine("服务2开启");
            ServiceHost sh3 = new ServiceHost(typeof(WcfLib.Unity.Unity));
            sh3.Open();
            Console.WriteLine("服务3开启");
            Console.ReadKey();
        }

　　服务配置文件

客户端

右键添加服务

配置文件自动生成

        static void Main(string[] args)
        {
            WCFServiceUser1.User1Client cli1 = new WCFServiceUser1.User1Client();
            WCFServiceUser2.User2Client cli2 = new WCFServiceUser2.User2Client();
            WCFServiceUnity.Unity1Client cli3 = new WCFServiceUnity.Unity1Client();
            WCFServiceUnity.Unity2Client cli4 = new WCFServiceUnity.Unity2Client();
            Console.WriteLine(cli1.GetUser1Name("name1"));
            Console.WriteLine(cli2.GetUser1Name("name2"));
            Console.WriteLine(cli3.GetUnityCount());
            Console.WriteLine(cli4.GetUnityString());
        }

WCF 调用服务标准写法

static void Main(string[] args)
        {
            //不适用using，原因using在网络中断时，wcf不能关闭。websevice可以是用using释放，websevice标准写法是用using
            CustomService.UserServiceSoapClient ucli = null;
            try
            {
                ucli = new CustomService.UserServiceSoapClient();
                ucli.GetStr("");
                //手动释放，
                ucli.Close();
            }
            catch (Exception)
            {
                if (ucli != null)
                {
                    ucli.Abort();
                }
            }
        }
