View returns null to controller action

Question

I'm using razor view to display the info and the info display perfectly but when I press the action link to download the file the action comes null from the view.

View:

@model Innovation_Internship.Models.Applicant

@Html.ActionLink("Download", "Download", "Admin", new { filename = Model.Resume })

Controller:

 public ActionResult Download(string filename) <-- comes null
    {
        try
        {

        }
        catch (Exception)
        {
            //download failed 
            //handle exception
            throw;
        }
    }

You were able to see it come back over the wire as null, have you checked to make sure it is not going out as null? — Ross Bush, May 09 '19 at 12:41
@RossBush filename has the value but when I press the link in the controller comes null. — Jonathan Padilla, May 09 '19 at 12:45
Can you post the body and/or url of your trace when you press download in the browser? — Ross Bush, May 09 '19 at 12:48

Model.Resume seems to be an object rather than as string. Maybe the object or refrence is null. - maybe use .ToString()

Also add null to the end or you may call the wrong version of the function

@Html.ActionLink("Text","Action","Controller", new { item.ID }, null)
