Question

我对ASP.NET MVC还是很陌生。我正在创建一个假期跟踪应用程序，并试图为每个员工创建一个详细信息页面。我希望该页面显示一个表，该表显示员工已采取的所有假期请求的表。我已经使它工作了，但只显示了一行。

这是我的模特

public partial class Employee
{
    public int EmployeeID { get; set; }
    public string FullName { get; set; }
    public string EmailID { get; set; }
    public string Password { get; set; }
    public System.DateTime StartDate { get; set; }
    public int RoleID { get; set; }
    public int ShiftID { get; set; }
    public int AreaID { get; set; }
    public int DisciplineID { get; set; }
    public int SiteID { get; set; }
    public int ALCategory { get; set; }
    public Nullable<int> HoursTaken { get; set; }
    public Nullable<int> AwardedLeave { get; set; }
    public Nullable<int> TotalHoursThisYear { get; set; }
    public int HoursCarriedForward { get; set; }
    public Nullable<int> EntitlementRemainingThisYear { get; set; }
    public string Comments { get; set;}

}

员工模型：

 public class EmployeeViewModel
{
    public Employee Employee { get; set; }

    public HolidayRequestForm HolidayRequestForm { get; set; }
}

假日申请表模型：

 public partial class HolidayRequestForm
{
    public int RequestID { get; set; }
    public int EmployeeID { get; set; }
    public System.DateTime StartDate { get; set; }
    public System.DateTime FinishDate { get; set; }
    public int HoursTaken { get; set; }
    public string Comments { get; set; }
    public int YearCreated { get; set; }
    public int MonthCreated { get; set; }
    public Nullable<int> DayCreated { get; set; }
    public Nullable<int> YearOfHoliday { get; set; }

    public virtual Employee Employee { get; set; }
}

控制器操作：

 public ActionResult Details(int? id)
      {
        Employee employee =  db.Employees.FirstOrDefault(emp => emp.EmployeeID == id);
        HolidayRequestForm holidayRequestForm db.HolidayRequestForms.FirstOrDefault(emp => emp.EmployeeID == id);



        EmployeeViewModel employeeViewModel = new EmployeeViewModel()
           {
               Employee = employee,
               HolidayRequestForm = holidayRequestForm,

           };

        return View(employeeViewModel);


    }

My View只是一个HTML表，用于显示数据库中的数据。所以问题是如何显示多个行或条目？我使用的是FirstorDefault吗？

您必须更改Employee Model并为Holiday声明一个列表：

员工模型：

public class EmployeeViewModel
{
    public Employee Employee { get; set; }

    public List<HolidayRequestForm> HolidayRequestForm { get; set; }
}

控制器操作：

public ActionResult Details(int? id)
{
        Employee employee =  db.Employees.FirstOrDefault(emp => emp.EmployeeID == id);
        List<HolidayRequestForm> holidayRequestForm = db.HolidayRequestForms.Where(emp => emp.EmployeeID == id).ToList();



        EmployeeViewModel employeeViewModel = new EmployeeViewModel()
           {
               Employee = employee,
               HolidayRequestForm = holidayRequestForm,

           };

        return View(employeeViewModel);


}

ASP.NET显示多个条目/行
