Count Controls in a Page in C#

Here is a simple method I created to count all the controls in a C#.NET page recursively.

       int ControlCount( Control parentControl )
       {
           int current=0;
           foreach( Control c in parentControl.Controls )
           {
               if (c.Controls.Count > 0)
               {
                   current += ControlCount(c);
               }
               else
               {
                   current++;
               }
           }
           return current;
       }
