Question

The odd thing is that something like System.IO.File.Delete() works
and the file gets deleted but will give “access to path is denied error” for .Move() operation.
All files are located in the same folder, user “Network service” has all
full control rights for the folder and all subfolders in it etc.

Folders are located in the project directory and can be seen in solution explorer.

Exception Details: System.UnauthorizedAccessException: Access to the path is denied.

      foreach(var info in FileActions.Where(x => x.OldSortOrder != x.SortOrder))
    {
        string FileToRename;
        string NewName;
        string OldFilePath;
        string OldFileThumbPath;


            FileToRename = info.ProductID + "/" + info.OldSortOrder + "-" + info.ImageID + ".jpg";
            NewName = info.SortOrder + "-" + info.ImageID + ".jpg";
            OldFilePath = System.Web.HttpContext.Current.Request.MapPath("~/Content/ProductImages/"  + FileToRename);
            OldFileThumbPath = System.Web.HttpContext.Current.Request.MapPath("~/Content/ProductImages/" + info.ProductID + "/thumbs/" + FileToRename);

            System.IO.File.Move(OldFilePath, NewName);
            System.IO.File.Move(OldFileThumbPath, NewName);



    }

Answer 1

Its because you map the path for the first files but not for the NewName.

So did not have the full path to know what to rename/move the file, and needs the full path to work correctly.

With out the path this is probably try to move it on the default folder of the asp.net pool that is probably don’t have this permissions.

So the code will be

NewName = System.Web.HttpContext.Current.Request.MapPath("~/Content/ProductImages/"  
     + info.SortOrder + "-" + info.ImageID + ".jpg" );

and debug this lines to see if the directories and files are all correct.
