C# 周和日实体

我正在用ASP.NET学习C和MVC。我正在制作一个应用程序，它获取每日数据并将其拆分为几周

我的问题是：我应该如何制作实体？我想要它，这样你就有一个星期和一个星期，你用它们来显示，编辑和创建数据和表格。例如，WeekNo=1和DayNo=1将是第1周的星期一。WeekNo=1和DayNo=2将是星期二，依此类推

我是新手，不太擅长信息管理。我需要外键吗

我在想：

public class Day
{
    public int WeekNo { get; set; }
    public int DayID { get; set; }
    public int DayNo { get; set; }
    public string DayofWeek { get; set; }

    //then other declarations, not important

    [ForeignKey("DayNo")]
}

public class Week
{
    public int ID { get; set; }
    public int WeekNo { get; set; }
    public int DayofWeek { get; set; }
}

外键是在一天或一周内使用，还是我需要它？

假设您在说实体时是指对象

以下是如何构造每天使用的对象：

否则，您可以使用以下每周使用的结构：

如果本周已经存在此对象，您也可以从某处获取此对象

现在，每日目标：

//Declare the weekly object:
myWeeklyObject thisWeek = new myWeeklyObject();
//Populate variables of thisWeek here:
thisWeek.ObjectID = thisWeek.WeekNo = CultureInfo.InvariantCulture.Calendar.GetWeekOfYear(DateTime.Now, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
//The line above gets the current weekNo for the year.

//Get the day of the week as an int:
int dayOfWeek = (int)DateTime.Now.DayOfWeek + 1; //DayOfWeek is 0 based
//Daclare object for a specific day:
myDataObject newObject = new myDataObject();
//Populate variables of newObject here.
//Then add it with the int dayOfWeek as the Key to the DataByDay Dictionary.
thisWeek.DataByDay.Add(dayOfWeek, newObject);

我希望这能回答你的问题和未来的问题，比如如何获得周末，或者至少对你有所帮助

祝你好运。

你对实体到底是什么意思？代码中的对象？视图中的元素？数据库中的表？还有，您希望每天或每周都有一个实例吗？好的，我发布了我的答案，如果您是指代码中的对象，每周和每天都有。希望对你有帮助，教授，我对这个很陌生。我的意思是数据库中的表。你的答案也适用于他们吗？我希望能够点击一周，它会显示所有的日子，然后当我选择一天时，它会显示当天的读数。

//Declare the weekly object:
myWeeklyObject thisWeek = new myWeeklyObject();
//Populate variables of thisWeek here:
thisWeek.ObjectID = thisWeek.WeekNo = CultureInfo.InvariantCulture.Calendar.GetWeekOfYear(DateTime.Now, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
//The line above gets the current weekNo for the year.

//Get the day of the week as an int:
int dayOfWeek = (int)DateTime.Now.DayOfWeek + 1; //DayOfWeek is 0 based
//Daclare object for a specific day:
myDataObject newObject = new myDataObject();
//Populate variables of newObject here.
//Then add it with the int dayOfWeek as the Key to the DataByDay Dictionary.
thisWeek.DataByDay.Add(dayOfWeek, newObject);
