Question

我尝试编写一个程序，将XML文件转换为按日期排序 XML文件如下所示：

    </Order>
</Orders>
    </Root>

我希望按 OrderDate 进行排序但我不知道该怎么做。任何人都可以给我任何建议吗？

Answer 1

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();

这是OrderDate订购的所有订单记录的列表

如果您希望将其存储在文件中，请使用“记录”作为数据源重新创建XML文件

Answer 2

我使用了Linq XML。我认为添加到新的XML元素比分类原始

更容易

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input =
                "<Root>" +
                    "<Orders>" +
