範例
下列範例示範 Add 類別的 InstallerCollection 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，則會採用先前元件的選項。 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。

備註
提供 InstallerCollection 應用程式管理物件集合 Installer 所需的方法和屬性。
使用下列三種方式之一，將安裝程式新增至集合：
方法 Add 會將單一安裝程式新增至集合。
方法 AddRange 會將多個安裝程式新增至集合。
方法和 InsertItem[] 屬性，也就是 InstallerCollection 索引器，每個都會將單一安裝程式新增至集合中指定的索引處。
透過 Remove 方法移除安裝程式。 使用 Contains 方法檢查安裝程式是否在集合中。 使用 IndexOf 方法尋找安裝程式在集合中的位置。
當包含集合的安裝程式如 Installer.Parent 屬性所指定，呼叫其 Install、 Commit、 Rollback或 Uninstall 方法時，就會執行集合中的安裝程式。
如需安裝程式集合使用方式的範例，請參閱 AssemblyInstaller 和 TransactedInstaller 類別。
