如果您希望为 SharePoint 项目中的部署步骤执行其他任务,则可以在 Visual Studio 执行每个部署步骤的前后处理由 SharePoint 项目项引发的事件。 有关更多信息,请参见扩展 SharePoint 打包和部署。
在执行部署步骤时运行代码
- 创建项目项扩展、项目扩展或新项目项类型的定义。 有关更多信息,请参见下列主题: 
- 在扩展中,处理 ISharePointProjectItemType 对象(在项目项扩展或项目扩展中)或 ISharePointProjectItemTypeDefinition 对象(在新项目项类型的定义中)的 DeploymentStepStarted 和 DeploymentStepCompleted 事件。 
- 在事件处理程序中,使用 DeploymentStepStartedEventArgs 和 DeploymentStepCompletedEventArgs 参数获取有关部署步骤的信息。 例如,您可以确定正在执行哪一个部署步骤以及是部署还是收回解决方案。 
示例
下面的代码示例演示如何在“列表实例”项目项的扩展中处理 DeploymentStepStarted 和 DeploymentStepCompleted 事件。 若 Visual Studio 在部署和收回解决方案时回收应用程序池,则此扩展会向**“输出”**窗口中写入一条附加消息。

编译代码
此示例需要对以下程序集的引用:
- Microsoft.VisualStudio.SharePoint 
- System.ComponentModel.Composition 
部署扩展
若要部署扩展,请为要随此扩展分发的程序集和任何其他文件创建 Visual Studio 扩展 (VSIX) 包。 有关更多信息,请参见在 Visual Studio 中部署 SharePoint 工具扩展。
