Each control has a Controls property which in fact is a ControlCollection. This collection itself has a method Find() which takes 2 parameters. The first parameter is the name of the control which you want to find, the second parameter indicates wether to include all children into the search.

As a sample:

Control[] allButton1 = this.Controls.Find("button1", true);
// for your example
Control[] foundControls = this.Controls.Find(root.Name,true);

You can use root.Name in place of root.ID in win forms.
