我有一個Datatable Cities包含以下數據（我發佈的60000個項目中只有3個）。如何從數據表生成xml文件
我想從提供的數據中創建一個xml（KML）。
如何創建通用解決方案？
也許創建類和添加屬性，然後加載到XML。
這將是generated.i我只張貼的部分XML

編輯 模板小的變化，這兩個文件是一個LINES和其他有對於POINTS。如果我有內部街道，那麼它應該被添加在兩個文檔section.i編輯我的問題的地標。如何做到這一點？如果我使用此代碼，它我s複製

代碼有什麼你試過嗎？ – CodeNotFound
你可以加載數據到一個DataSet然後使用編寫結果一個XML文件在下面的'C＃Stackoverflow導出數據表到XML文件'做一個谷歌搜索 – MethodMan
DataTable附帶一個[WriteToXml方法]（https://msdn.microsoft .com/en-us/library/system.data.datatable.writexml（v = vs.110）.aspx）...只需使用Xslt轉換生成的Xml。不應該太難。 – Filburt
