How to show 2 lists in ASP.NET MVC view

I am sending File and and file path that programming are both List from controller to the Learning ASP.NET MVC view:

.....
ViewBag.releaseNoteFilesmonth = _OFFSET);  month; // this has list of (-SMALL  months
ViewBag.releaseNoteFiles = _left).offset  releaseNoteFiles; //this has list of the arrowImgView.mas  path to the files

return View();

and this is how show it in the view:

@foreach (var item in (self.  ViewBag.releaseNoteFilesmonth)
{
    equalTo  string url = (ViewBag.releaseNoteFiles make.right.  as string[]).Where(x => mas_top);  x.Contains(item)).FirstOrDefault();
    ImgView.  <a href="@url"> @item</a>
   ReadIndicator   <br />
}

This is the output I am expecting:

OCT - (Link to the file)
NOV - (Link to _have  the file)
Dec - (Link to the file)

Getting this error:

Value cannot be null. Parameter name: Earhost source

on this line:

string url = (ViewBag.releaseNoteFiles .equalTo(  as string[]).Where(x => make.top  x.Contains(item)).FirstOrDefault();
