当我想要dd/MM/yyyy时，MVC 5日期格式在编辑中显示为MM/dd/yyyy

Question

我知道这是一个老问题，已经回答了很多次，但我已经搜索了好几个月都没有解决我的问题。我的应用程序只是本地的，需要是en AU。我是一个新手，我发现的答案与MVC 5没有的全局文件有关，所以我完全困惑(我认为我使用Startup.cs？？(。不知道我需要自定义路线还是自定义模型活页夹。

型号

{
public partial class SuspensionHist
{
[Key]
[Column(Order = 0)]
public int AssociId { get; set; }
[Key]
[Column(Order = 1)]
public short SuspensionNo { get; set; }
[Key]
[Column(Order = 2)]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
public DateTime SuspensionDate { get; set; }
public short? OffenceNo { get; set; }
public bool? SuspensionServed { get; set; }
public byte[] SsmaTimeStamp { get; set; }
}
}

控制器

//GET：挂起历史记录/编辑/5公共异步任务编辑(int？AssociId，short？SuspendionNo，DateTime SuspendionDate({if(AssociId==null({return NotFound((；}

if (SuspensionNo == null)
{
return NotFound();
}
if (SuspensionDate == null)
{
return NotFound();
}
var suspensionHist = await _context.SuspensionHist.FindAsync(AssociId, SuspensionNo, SuspensionDate);
if (suspensionHist == null)
{
return NotFound();
}
ViewBag.SuspensionNo = new SelectList(_context.Suspension, "SuspensionNo", "SuspensionNo");
return View(suspensionHist);
}

感谢Yas Ikeda所做的以下工作：问题在于URL中的"/"。在索引视图上，我已将链接从更改为

@Html.ActionLink("Edit", "Edit", new { AssociId = item.AssociId, SuspensionNo = item.SuspensionNo, CalendarDate = item.CalendarDate.ToString("dd/MM/yyyy") })

至

<a asp-action="Edit" asp-route-Associid="@item.AssociId" asp-route-SuspensionNo="@item.SuspensionNo" asp-route-SuspensionDate="@item.SuspensionDate.ToString("o")">Edit</a>

这修复了路由问题，编辑现在工作正常。
