快速設置類屬性

Question

class UserClass{ 

    #region Class properties which are binding from DB 
    . 
    . 
    . 
    #endregion 


    #region Constructor Methods 
    public UserClass(int _iUser_id) 
    { 
     // of course this is wrong but how can i quickly set properties 
     // which are coming from DB by extension method over context class? 
     this = DAO.context.GetById<UserClass>(_iUser_id); 
    } 
    #endregion 
} 

Answer 1

你可以使用一個靜態方法，而不是一個構造函數：

public static UserClass GetById(int userId) { 
    return DAO.context.GetById<UserClass>(userId); 
} 

Answer 2

您需要手動設置屬性。

如果您確實想要，您可以使用反射或表達式樹來遍歷屬性，但它可能不值得。
