我在asp.net mvc非常新手.在这里我有一个问题在控制器图像上传谁都可以给予帮助？我从互联网上获得的这个示例控制器,我应该更改和编码viewnya,这里我想通过"AvatarUrl"保存图像

模型> EmployeeServices

public class EmployeeModel{

    [ScaffoldColumn(false)]
    public int EmployeeID { get; set; }

    [Required(ErrorMessage = "Please Enter Position ID")]
    public int PositionID { get; set; }

    [Required(ErrorMessage = "Please Enter NO PEK")]
    public string NoPEK { get; set; }

    [Required(ErrorMessage = "Please Enter NO KTP")]
    public string NoKTP { get; set; }

    [Required(ErrorMessage = "Please Enter TaxID")]
    public string TaxID { get; set; }

    [Required(ErrorMessage = "Please Enter FirstName")]
    public string FirstName { get; set; }

    [Required(ErrorMessage = …

我目前正在从数据库中获取2个日期并找出它们之间的差异.我在视图页面中显示总和的值,但它当前显示为小数.例如,产生的值之一是1585.913,但我想用HH:MM:SS格式.

我当前显示小数值的代码如下所示.

调节器

public ActionResult Execution(int id = 0)
    {
        Execution execution = db.Executions.Find(id);

        if (execution == null)
        {
            return HttpNotFound();
        }

        ViewBag.ExecutionSeconds = (execution.End - execution.Start).TotalSeconds;

        return View(execution);

    }

视图

@ViewBag.ExecutionSeconds

我必须对此代码进行哪些更改才能以HH:MM:SS格式显示该值？

提前致谢.
