示例
下面的示例演示 Add 类的 InstallerCollection 方法。 此示例提供类似于 Installutil.exe (Installer Tool) 的实现。 它安装具有该特定程序集前面的选项的程序集。 如果未为程序集指定选项，则当列表中有上一个程序集时，将采用上一个程序集的选项。 如果指定了“/u”或“/uninstall”选项，则卸载程序集。 如果提供了“/？”或“/help”选项，则会向控制台显示帮助信息。

注解
InstallerCollection提供应用程序管理对象集合Installer所需的方法和属性。
使用以下三种方法之一将安装程序添加到集合：
方法 Add 将单个安装程序添加到 集合。
方法 AddRange 将多个安装程序添加到 集合。
方法和 InsertItem[] 属性（即 InstallerCollection 索引器）各自将单个安装程序添加到集合中的指定索引处。
通过 Remove 方法删除安装程序。 使用 Contains 方法检查安装程序是否在集合中。 使用 IndexOf 方法查找安装程序在集合中的位置。
当包含集合的安装程序（由 Installer.Parent 属性指定）调用其 Install、 Commit、 Rollback或 Uninstall 方法时，将运行集合中的安装程序。
有关安装程序集合用法的示例，请参阅 AssemblyInstaller 和 TransactedInstaller 类。
