Use Server.MapPath('~/') to get the root path of your web-app. Calling"~/Hospital/uploads/" will lead to the file "C:\Program Files (x86)\IIS Express\" the IIS folder which is used to run your app.

You can do something like this.

 Server.MapPath("~/Hospital/uploads/" + r[i].Name);

Use this method to delete the file. https://msdn.microsoft.com/en-us/library/system.io.file.delete(v=vs.110).aspx
