如何从 C# 控制器发送 2 个列表以使用 ViewBag 查看

Question

我将月份（从文件路径中获取值）和文件路径发送到 MVC 视图，以便我可以显示链接到文件的月份列表以像这样下载它：

 OCT(that is linked to file path)
 Nov (that is linked to file path)
 December (that is linked to file path)

这是我的控制器 C# 代码：

     public ActionResult Help()
    {

        var releaseNoteFiles = Directory.GetFiles(Server.MapPath("~/Content/ReleaseNotes"));

        List<string> month = new List<string>();
        foreach (var releaseNoteFile in releaseNoteFiles)
        {
            month.Add(new Regex("([^A-Z]*)([a-zA-Z]*)").Match(Path.GetFileNameWithoutExtension(releaseNoteFile).Split('.').Last()).Groups[2].Value);
        }
        ViewBag.releaseNoteFilesmonth = month;   /Has October,Nov,...
        ViewBag.releaseNoteFiles = releaseNoteFiles; /Has Path to the File

        return View();
    }
    

这是我的观点，我对如何发送 2 个列表（文件名和路径）有疑问 此代码显示列表 2 次。

          @foreach (var item in ViewBag.releaseNoteFilesmonth)
                    {foreach (var item2 in ViewBag.releaseNoteFiles)
                        {
                            @item <a href="@item2">@item</a>
                            <br />
                        }
                      }

您似乎想在视图上打印带有超链接的月份和月份文件，如果可以解决问题，请参阅下面的代码。

@foreach (var item in ViewBag.releaseNoteFilesmonth)
{
    var matchedmonthfile = (ViewBag.releaseNoteFiles as string[]).Where(x => x.Contains(item)).FirstOrDefault();
    @item <a href="@matchedmonthfile">@matchedmonthfile</a>
    <br />
}
