c# - Why is access to the path denied?

Question

I am having a problem where I am trying to delete my file but I get an exception.

if (result == "Success")
{
     if (FileUpload.HasFile)
     {
         try
         {
              File.Delete(Request.PhysicalApplicationPath + app_settings.login_images + txtUploadStatus.Text);
              string filename = Path.GetFileName(btnFileUpload.FileName);
              btnFileUpload.SaveAs(Request.PhysicalApplicationPath + app_settings.login_images + filename);
         }
         catch (Exception ex)
         {
               Message(ex.ToString());
         }
      }
}

Also I should note that the folder I am trying to delete from has full control to network services.

The full exception message is:

System.UnauthorizedAccessException: Access to the path 'C:UsersgowdynDocumentsVisual Studio 2008Projectshybridhybridemp_loginimagesenviromental.jpg' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.Delete(String path) at hybrid.User_Controls.Imgloader_Add_Edit_Tbl.btnUpdate_Click(Object sender, EventArgs e) in C:UsersgowdynDocumentsVisual Studio 2008ProjectshybridhybridUser_ControlsImgloader_Add_Edit_Tbl.ascx.cs:line 242

Any ideas?

According to File.Delete Method...

An UnauthorizedAccessException means one of 4 things:

• The caller does not have the required permission.
• The file is an executable file that is in use.
• Path is a directory.
• Path specified a read-only file.
