通过

WorkbookBase.AfterXmlImport 事件

  • 项目

在刷新现有 XML 数据连接后或将新 XML 数据导入工作簿后发生。

命名空间：  Microsoft.Office.Tools.Excel
程序集：  Microsoft.Office.Tools.Excel.v4.0.Utilities（在 Microsoft.Office.Tools.Excel.v4.0.Utilities.dll 中）

语法

声明
Public Event AfterXmlImport As WorkbookEvents_AfterXmlImportEventHandler

public event WorkbookEvents_AfterXmlImportEventHandler AfterXmlImport

示例

下面的代码示例演示如何将 XML 数据导入工作簿。此示例创建一个包含客户名称的 DataSet，并将基于该 DataSet 的 XML 架构的 XmlMap 添加到当前工作簿的 XmlMaps 集合。然后，此示例调用 XmlImportXml 方法将数据导入工作表 Sheet1。调用 XmlImportXml 方法时，BeforeXmlImport 事件处理程序会提示用户继续或取消导入 XML，然后 AfterXmlImport 事件处理程序会报告是否成功导入了 XML。

此示例针对的是文档级自定义项。
