CategoryNameCollection クラス

カテゴリ名の文字列のコレクションを表します。

名前空間: System.Drawing.Design
アセンブリ: System.Drawing (system.drawing.dll 内)
構文

Visual Basic (宣言)

Public NotInheritable Class
 CategoryNameCollection
    Inherits ReadOnlyCollectionBase

Visual Basic (使用法)

Dim instance As CategoryNameCollection

public sealed class CategoryNameCollection
 : ReadOnlyCollectionBase

C++

public ref class CategoryNameCollection sealed
 : public ReadOnlyCollectionBase

public final class CategoryNameCollection extends
 ReadOnlyCollectionBase

JScript

public final class CategoryNameCollection extends
 ReadOnlyCollectionBase

解説

このコレクションは、ツールボックスのカテゴリ名のコレクションを格納するために使用されます。

使用例

次に示すのは、コントロールがデザインモードで配置されている場合に IToolboxService を取得するコード例です。このコードは、IToolboxService が取得されると、そこから各ツールボックスカテゴリの名前を取得し、それぞれの名前をコントロールの表面に描画します。
