快速设置类属性

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

您需要手动设置属性。

如果你真的想，你可以使用反射或表达树来遍历属性，但它可能不值得。

Answer 2

您可以使用静态方法而不是构造函数：

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