WCF(Codefirst)

Codefirst与Contractfirst相对应，先对代码进行编写，然后进行服务的定义！

项目一：类库项目。先定义完相应的数据实体，然后定义服务。

    [DataContract(Name = "People")]

    public class People//数据实体类

    {

        private string _name;

        private int _age;

        private string _hometown;

 

        [DataMember(Name = "P_Name")]

        public string Name

        {

            get

            {

                return _name;

            }

            set

            {

                _name = value;

            }

        }

 

        [DataMember(Name = "P_Age")]

        public int Age

        {

            get

            {

                return _age;

            }

            set

            {

                _age = value;

            }

        }

 

        [DataMember(Name = "P_Hometown")]

        public string Hometown

        {

            get

            {

                return _hometown;

            }

            set

            {

                _hometown = value;

            }

        }

}

 

  [ServiceContract]

    public interface IPeopleContract //定义服务

    {

        [OperationContract]

        void SetMan(People man);

 

        [OperationContract]

        People GetMan();

    }

 

    public class PeopleContract : IPeopleContract //针对服务的实现

    {

        People _man;

        #region IPeopleContract 成员

 

        public void SetMan(People man)

        {

            _man = man;

        }

 

        public People GetMan()

        {

            return _man;

        }

 

        #endregion

    }
