次のコード例は、コレクションControlCollectionのインスタンスが作成ControlCollectionされたときに、メソッドをオーバーライドしてOwner 、メッセージ (プロパティの名前を含む) をトレースログに書き込むカスタムクラスです。The following code example is a custom ControlCollection class that overrides the ControlCollection method to write messages (which include the name of the Owner property) to the trace log when an instance of the collection is created. この例を使用するには、ページまたはアプリケーションのトレースを有効にする必要があります。You must enable tracing for the page or application for this example to work.

// Create a custom ControlCollection that writes
// information to the Trace log when an instance
// of the collection is created.
[AspNetHostingPermission(SecurityAction.Demand, Level=AspNetHostingPermissionLevel.Minimal)]
public class CustomControlCollection : ControlCollection
{
	private HttpContext context;

	public CustomControlCollection(Control owner)
		: base(owner)
	{

		HttpContext.Current.Trace.Write("The control collection is created.");
		// Display the Name of the control
		// that uses this collection when tracing is enabled.
		HttpContext.Current.Trace.Write("The owner is: " + this.Owner.ToString());
	}
}

' information to the Trace log when an instance
' of the collection is created.
