WorkbookBase.AfterXmlExport 事件

  • 项目

在 Microsoft Office Excel 保存工作簿的数据或将数据从工作簿导出到 XML 数据文件后发生。

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 AfterXmlExport As WorkbookEvents_AfterXmlExportEventHandler

public event WorkbookEvents_AfterXmlExportEventHandler AfterXmlExport

示例

下面的代码示例演示如何从工作簿中导出 XML 数据。 该示例将 XML 数据从 DataSet 导入到当前工作簿的 XmlMap 中。 然后，该示例调用 SaveAsXMLData 方法将数据从 XmlMap 导出到 XML 文件中。 调用 SaveAsXMLData 方法时，BeforeXmlExport 事件处理程序报告正在导出 XML，并且 AfterXmlExport 事件处理程序报告是否已成功导出 XML。

此示例针对的是文档级自定义项。

    dt.Columns.Add(New DataColumn("LastName"))
