如何：响应 ClickOnce 发布事件

使用 ClickOnce 可以将 Windows 应用程序发布到 Web 服务器或进行网络文件共享以进行简化安装。有关更多信息，请参见 ClickOnce 安全和部署。

Visual Studio 核心自动化模型（包含在 EnvDTE80 中）具有一个名为 PublishEvents 的事件处理对象。它可以用于检测 ClickOnce 部署开始 (OnPublishBegin) 和结束 (OnPublishDone) 的时间。您可以根据这些事件执行操作。下面的过程演示如何处理这些事件。

说明
显示的对话框和菜单命令可能会与“帮助”中的描述不同，具体取决于您现用的设置或版本。这些过程是在“常规开发设置”处于活动状态时开发的。若要更改设置，请在“工具”菜单上选择“导入和导出设置”。有关更多信息，请参见 Visual Studio 设置。

响应 ClickOnce 事件

1. 在新建的或现有的外接程序中，将下列代码添加到 Connect 类中。

2. 按照如何：使用外接程序管理器控制外接程序中所述生成和激活外接程序。

3. 按照 ClickOnce 安全和部署中所述开始 ClickOnce 部署操作。

   在部署开始和结束时会出现一个消息框。
