轉換XML文件的排序

我想寫轉換XML文件給該程序的分類排序，按日期的XML文件是這樣的：轉換XML文件的排序

我希望它進行排序通過OrderDate但我不知道該怎麼做。任何人都可以給我任何建議嗎？

沒有直接的方法對文件數據進行排序。您可以閱讀該文件，創建XML對象（反序列化等），對該對象進行排序並在需要時寫回文件。 –

是的，我想要那個。我該怎麼做？ –

你的目標是什麼？有一個xml文件，其中的條目按* OrderDate *排序或讀取和寫入xml文件的程序？如果您只是希望對該XML文件進行排序（但我不確定是否要對XML的主要用途進行排序），則可以使用XSL進行排序。你想編寫一個程序，我的第一種方法是創建一些代表ORDER，CUSTOMER等的對象，讀取文件並創建對象，將它們存儲在一個列表中，對列表進行排序並將列表作爲XML文件存放再次。 – mnille

XDocument xDoc = XDocument.Parse(xmlDoc);//xmlDoc = your xml file or input stream 
IList<XElement> records = xDoc.Root.Elements("Order").OrderBy(x => x.Element("OrderDate").Value).ToList();

這是通過訂購日期

下令所有訂單記錄的列表。如果你想在一個文件中，使用「記錄」作爲數據源重新創建XML文件

'x.Element（「OrderDate」）。Value'將是字符串，嘗試將其轉換爲'DateTime'。 –

用.ToShortDateString（）替換.Value也許？對此沒有做太多的工作... –

或追加：Value.ToShortDateString（） –

我使用的LINQ XML。我認爲添加新的XML元素要比對原始文件進行排序要容易得多
