我的第一个WCF程序

写WCF，VS需要一管理员身份呢启动，否则服务无法访问。

model层

using System;
using System.Runtime.Serialization;

namespace MyModel
{
    [DataContract]
    public class User
    {
        [DataMember]
        public int Id { get; set; }
        [DataMember]
        public string UserName { get; set; }
        [DataMember]
        public string Password { get; set; }
        [DataMember]
        public string Truename { get; set; }
        [DataMember]
        public string Sex { get; set; }
        [DataMember]
        public DateTime Birthday { get; set; }
        [DataMember]
        public string Phone { get; set; }
        [DataMember]
        public string Email { get; set; }
        [DataMember]
        public DateTime CreateTime { get; set; }
    }
}

using System.Runtime.Serialization;

namespace MyModel
{
    [DataContract]
    public class FaultMessage
    {
        [DataMember]
        public string Message { get; set; }
        [DataMember]
        public string ErrorCode { get; set; }
    }
}

manager层

using MyDao.ModelRecords;
using MyModel;

}

using MyDao;
using MyDao.Interface;

contract层

using MyModel;

using System.ServiceModel;

namespace MyContract
{
    [ServiceContract(Name = "UserService", Namespace = "http://www.artech.com/")]
    public interface UserContract
    {
        [OperationContract]
        [FaultContract(typeof(FaultMessage))]
        int Insert(User user);

        [OperationContract]
        [FaultContract(typeof(FaultMessage))]
        void Delete(int id);

        [OperationContract]
        [FaultContract(typeof(FaultMessage))]
        void Update(User user);

        [OperationContract]
        [FaultContract(typeof(FaultMessage))]
        User GetUserById(int id);
    }
}

service层：

using MyContract;
using MyManager;
using MyManager.Interface;
using MyModel;

using System;
using System.ServiceModel;

namespace MyServices
{
    public class UserService : UserContract
    {
        private IUserManager userManager = new UserManager();

        public int Insert(User user)
        {
            int id = 0;
            try
            {
                id = userManager.Insert(user);
            }
            catch (Exception ex)
            {
                throw new FaultException<FaultMessage>(new FaultMessage { ErrorCode = "insert", Message = ex.Message });
            }

            return id;
        }

        public void Delete(int id)
        {
            try

            }
            catch (Exception ex)
            {
                throw new FaultException<FaultMessage>(new FaultMessage { ErrorCode = "delete", Message = ex.Message });
            }
        }

        public void Update(User user)
        {
            try
            {
                userManager.Update(user);
            }
            catch (Exception ex)
            {
                throw new FaultException<FaultMessage>(new FaultMessage { ErrorCode = "update", Message = ex.Message });
            }
        }

        public User GetUserById(int id)
        {
            try
            {
                return userManager.GetUserById(id);
            }
