範例

下列範例加上建構函式中的 InstallException 範例，組成一個範例，其中顯示具有自己的安裝程式的元件。安裝程式名為 MyInstaller，其具有屬性 RunInstallerAttribute，表示安裝程式將會由 Installutil.exe (Installer Tool) 叫用此安裝程式。 Installutil.exe (安裝程式工具) 呼叫、 Rollback Install 和Uninstall方法Commit。中的 Commit 程式代碼假設名為 FileDoesNotExist.txt 的檔案存在，才能認可元件的安裝。如果檔案 FileDoesNotExist.txt 不存在， Commit 則引發 InstallException。同樣地， Uninstall 只有在名為 FileDoesNotExist.txt 的檔案存在時，才會發生卸載的情況。否則會 InstallException引發。在中 Rollback，會執行代碼段，這可能會引發例外狀況。如果引發例外狀況，就會攔截該例外狀況，並引發，並將 InstallException 該例外狀況傳遞給該例外狀況。

注意

使用 Installutil.exe 的說明執行此範例。在命令提示字元中輸入此值：

Installutil InstallException.exe

-或-

Installutil /u InstallException.exe
