名前空間: System.Configuration.Install
アセンブリ: System.Configuration.Install (system.configuration.install.dll 内)
構文

Visual Basic (宣言)

Public Enumeration UninstallAction

Visual Basic (使用法)

Dim instance As UninstallAction

public enum UninstallAction

C++

public enum class UninstallAction

public enum UninstallAction

JScript

public enum UninstallAction

メンバ

	メンバ名	説明
	NoAction	インストーラによって作成されたリソースをそのまま残します。
	Remove	インストーラによって作成されたリソースを削除します。

使用例

Installer クラスを継承するカスタムアンインストーラを作成する例を次に示します。この例では Uninstall 関数のオーバーライドで、ユーザー入力を基に UninstallAction 列挙体を設定します。ユーザー入力が "n" の場合、ユーザーが入力したイベントログのリソースに対してカスタムアンインストーラは一切の処理を行いません。"n" 以外の場合は、イベントログからリソースを削除します。
