Control.ControlCollection Class
Represents a collection of Control objects.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The Add, Remove, and RemoveAt methods enable you to add and remove individual controls from the collection. You can also use the AddRange or Clear methods to add or remove all the controls from the collection.
You can determine if a Control is a member of the collection by passing the control into the Contains method. To get the index value of the location of a Control in the collection, pass the control into the IndexOf method. The collection can be copied into an array by calling the CopyTo method.
The following code example removes a Control from the Control.ControlCollection of the derived class Panel if it is a member of the collection. The example requires that you have created a Panel, a Button, and at least one RadioButton control on a Form. The RadioButton controls are added to the Panel control, and the Panel control added to the Form. When the button is clicked, the radio button named radioButton2 is removed from the Control.ControlCollection.
