I'm displaying a text file on a webpage but do not want to show the .txt extension. How do I hide the extension?

What I have tried:

This is a sample of my code: I've tried to format "SiteFileName" to exclude the extension but I have not been successful.

<div class="col-xs-12">
                    @for (int c = 1; c <= ViewBag.NewFiles.Count; c++)
                    {
                        @*change Admits to File*@
                        iFTDTL.Areas.admits.Models.File a = ViewBag.NewFiles[c - 1];
                        <div class="col-xs-2">@c</div>
                        <div class="col-xs-5">@Html.ActionLink(a.SiteFilename, "DownloadFile", new { a.Id })</div>
                        <div class="col-xs-2">@a.RecordCount</div>
                        <div class="col-xs-3">@a.CreateDate.ToString("yyyy-MMM-dd")</div>                     
                    }
                </div>
