asp.net mvc视图的区域性特定日期/货币格式设置的正确位置在哪里?

class BirthdayDomain
{
    public DateTime Birthday { get; set; }

    public decimal BirthdayPresent { get; set; }
}

我有两个选项可以将其传递给强类型视图:

1.

class BirthdayView
{
    public DateTime Birthday { get; set; }

    public decimal BirthdayPresent { get; set; }
}

<%: Model.Birthday.ToString("d"); %>
<%: Model.BirthdayPresent.ToString("C2"); %>

2.

class BirthdayView
{
    public string Birthday { get; set; }

    public string BirthdayPresent { get; set; }
}

在控制器中(例如)

BirthdayDomain bd = Repository.GetBirthday(.....)
BirthdayView bv = new BirthdayView()
                  {
                       Birthday = bd.Birthday.ToString("d");
                       BirthdayPresent = bd.BirthdayPresent.ToString("C2");
                  }

在视图中只输出字符串。
