How to handle a controller result that returns a file in ASP.NET MVC

I have a controller that returns a file like this :
byte fileBytes=System.IO.File.ReadAllBytes(Path.Combine(Server.MapPath("~/Images/"), photoPath));
string fileName = prop;
return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
I can display it in HTML image like this
<div class="col-md-6"><img src="@("File/Download?id="+ Model.ID+"&prop=photo")" alt="Image" /></div>
I want to create a link using that controller, so that when user clicks it, it will show the image :
<div class="col-md-4"><a @(Model.path == null ? Html.ActionLink("click here", "Download", "File", new { appid = Model.ID.ToString(), prop = "photo" }, null) : Html.ActionLink("none", "", ""))</a></div>

The Html.ActionLink helper method will generate HTML markup for the anchor tag. Does not make sense to call it inside the opening a tag
A simple If condition can do.
<div class="col-md-4">
@if(Model.path == null)
{
@Html.ActionLink("click here", "Download", "File",
new { appid = Model.ID, prop = "photo" }, null);
}
else
{
<span>Nothing to download or even another link you can use here</span>
}
</div>

It worked but the downloaded file type looks like a generic file. How can I make it specific like .pdf or .jpg? How should I modify the controller? Thanks for the answer.

You need to fix your action method to send the correct content/mime type.For the image, get the content type usingMimeMapping.GetMimeMapping(fileName);method and use that. Refer theGetFilemethod in this answer
