範例

下列範例示範 TransactedInstaller類別的 TransactedInstaller 、 Install 和 Uninstall 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。

備註

呼叫這個方法以移除先前完成的安裝。這個 Uninstall 方法會 Uninstall 呼叫屬性中每個安裝程式的方法， Installers 以卸載安裝期間設定的任何資源。卸載期間的任何例外狀況都會被忽略。

注意

Install雖然和 Commit 方法會在安裝之後儲存計算機的狀態，但包含 IDictionary 參數的savedState檔案可能會在安裝完成之後於某個時間點刪除。如果刪除檔案，則 savedState 參數為 null。
