範例

下列範例示範 TransactedInstaller類別的 TransactedInstallerInstallUninstall 方法。

此範例提供與 Installutil.exe (Installer Tool) 類似的實作。 它會使用該特定元件前面的選項來安裝元件。 如果未為元件指定選項,則如果清單中有先前的元件,則會使用先前元件的選項。 如果指定了 “/u” 或 “/uninstall” 選項,則會卸載元件。 如果提供 “/?” 或 “/help” 選項,則會向控制台顯示說明資訊。

ArrayList^ myOptions = gcnew ArrayList;
String^ myOption;
bool toUnInstall = false;
bool toPrintHelp = false;
TransactedInstaller^ myTransactedInstaller = gcnew TransactedInstaller;

InstallContext^ myInstallContext;
