我有一个模型这个模型：

 public class Member
    {
        #region public property

        public int Id { get; set; }
        public string LastName { get; set; }
        public string FirstName { get; set; }
        public AccountState AccountState { get; set; }
        public GodFatherType GodFatherType { get; set; }
}

AccountState 和 GodFatherType 都是 2 个枚举：

 public enum AccountState 
{
    NotActivated = 0,
    Activated = 1,
    Desactived = 2,

}

 public enum GodFatherType
    {
        Undefined=0,
        unknown = 1,
        Correct = 2,
    }

在我有 Id、LastName、FistName、TinyIntAccountstateId 和smallintGodFatherTypeid 的数据库中，我不想更改我的存储过程如何映射我的类Member与数据库映射？

实际上，当我使用以下代码执行我的存储过程时，我只得到属性只有 Id、LastName、FistName：

 public sealed class DbContext : IDbContext
{
    private bool disposed;
    private SqlConnection connection;

    public DbContext(string connectionString)
    {
        connection = new SqlConnection(connectionString);
    }

    public IDbConnection Connection
    {
        get
        {
            if (disposed) throw new ObjectDisposedException(GetType().Name);

            return connection;
        }
    }

    public IDbTransaction CreateOpenedTransaction()
    {
        if (connection.State != ConnectionState.Open)
            Connection.Open();
        return Connection.BeginTransaction();
    }

    public IEnumerable<T> ExecuteProcedure<T>(string procedure, dynamic param = null, IDbTransaction transaction = null)
    {
        if (connection.State == ConnectionState.Closed)
        {
            connection.Open();
        }

        return Dapper.SqlMapper.Query<T>(connection, procedure, param, transaction,
            commandType: CommandType.StoredProcedure);
    }

    public int ExecuteProcedure(string procedure, dynamic param = null, IDbTransaction transaction = null)
    {
        if (connection.State == ConnectionState.Closed)
        {
            connection.Open();
        }

        return Dapper.SqlMapper.Execute(connection, procedure, param, transaction,
            commandType: CommandType.StoredProcedure);
    }

    public void Dispose()
    {
        Debug.WriteLine("** Disposing DbContext");

        if (disposed) return;

        if (connection != null)
        {
            connection.Dispose();
            connection = null;
        }

        disposed = true;
    }
}

最简单的选择是让它们保持 1:1，即

public AccountState AccountStateId { get; set; }
public GodFatherType GodFatherTypeId { get; set; }

在哪里

public enum AccountState : byte {...}
public enum GodFatherType : short {...}

如果无法重命名属性，则可以添加 shim 属性：

private byte AccountStateId {
    get { return (byte)(int)AccountState; }
    set { return AccountState = (AccountState)(int)value; }
}

也可以重命名地图中的成员，但这更复杂。
