ASP NET MVC 5 Delete File From Server

Question

View Code:

@if (File.Exists(Server.MapPath("~/Images/Cakes/" + Html.DisplayFor(modelItem => Model.CakeImage))))     {         @model TastyCakes.Models.Cakes         <form name="deletePhoto" action="/Cakes/DeletePhoto" method="post">         @Html.AntiForgeryToken()         File name of image to delete (without .jpg extension):         <input name="photoFileName" type="text" value="@Html.DisplayFor(modelItem => Model.CakeImage)" />         <input type="submit" value="Delete" class="tiny button">         </form>     } else {         <p>*File Needs to be uploaded</p> } 

Controller Code:

[HttpPost] [ValidateAntiForgeryToken] public ActionResult DeletePhoto(string photoFileName) {      ViewBag.deleteSuccess = "false";     var photoName = "";         photoName = photoFileName;     var fullPath = Server.MapPath("~/Images/Cakes/" + photoName);          if (File.Exists(fullPath))         {             File.Delete(fullPath);             ViewBag.deleteSuccess = "true";         } } 

Where it says if (File.Exists) AND File.Delete, the code has squiggly lines underneath it. So I am trying to figure out what syntax I need to get thif file deleted.

Here is a screenshot of my code in the controller:

UPPDATE: I have got the code working and created a simple code example on my blog on how I got it working and how the idea came about. http://httpjunkie.com/2014/724/mvc-5-image-upload-delete/

Answer 1

use Request.MapPath

string fullPath = Request.MapPath("~/Images/Cakes/" + photoName); if (System.IO.File.Exists(fullPath)) {    System.IO.File.Delete(fullPath); } 

Answer 2

File, as you're using it, is ambiguous, hence the "squiggly line". The IDE can't resolve which you mean;

System.Web.Mvc.Controller.File()

or

System.IO.File

Use a fully-qualified name when trying to use the File API within an MVC controller.
