public event WorkbookEvents_BeforeXmlImportEventHandler BeforeXmlImport

範例

下列程式碼範例示範如何將 XML 資料匯入活頁簿。 此範例建立含有客戶名稱的 DataSet，並根據 DataSet 的 XML 結構描述，將 XmlMap 加入至目前活頁簿的 XmlMaps 集合。 然後此範例會呼叫 XmlImportXml 方法，將資料匯入工作表 Sheet1。 當呼叫 XmlImportXml 方法時，BeforeXmlImport 事件處理常式會提示使用者繼續或取消匯入 XML，而且 AfterXmlImport 事件處理常式會報告 XML 是否已成功匯入。

這是示範文件層級自訂的範例。
