InstallerCollection 类

定义

包含要在安装过程中运行的安装程序的集合。

public ref class InstallerCollection : System::Collections::CollectionBase
public class InstallerCollection : System.Collections.CollectionBase
type InstallerCollection = class
    inherit CollectionBase
Public Class InstallerCollection
Inherits CollectionBase
继承
InstallerCollection

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 InstallCommitRollbackUninstall 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 AssemblyInstallerTransactedInstaller 类。
