I'm not completely sure that I understand you're issue. I've put the same basic code into place and it seems to work fine.
I can provide a list of the document names and I can select an individual item to display within an
tag. The code for my View is shown below:
<br />
<ul><br />
@foreach (var item in ViewBag.FileList)<br />
{<br />
<li>@item</li><br />
}<br />
</ul><br />
<br /><br />
<br /><br />
Item Number 2: <br /><br />
<img src="~/Content/Employees/@ViewBag.FileList[2]" /><br />
