例

次の例に加えて、 InstallException コンストラクターの例を組み合わせて、独自のインストーラーを持つアセンブリを示す例を構成します。 インストーラーには MyInstaller という名前が付けられ、属性 RunInstallerAttributeがあり、このインストーラーが Installutil.exe (インストーラー ツール) によって呼び出されることを示します。 Installutil.exe (インストーラー ツール) は、 Commit、 Rollback、 Install 、および Uninstallメソッドを呼び出します。 Commitのコードは、アセンブリのインストールをコミットする前に、FileDoesNotExist.txtという名前のファイルが存在することを前提とします。 ファイル FileDoesNotExist.txt が存在しない場合、 Commit は InstallExceptionを発生させます。 FileDoesNotExist.txtという名前のファイルが存在する場合にのみアンインストールが行われるUninstallの場合も同じです。 それ以外の場合は、 InstallExceptionが発生します。 Rollbackでは、コード フラグメントが実行され、例外が発生する可能性があります。 例外が発生すると、例外がキャッチされ、その例外が渡された状態で InstallException が発生します。
