问题描述

我试图编写一个程序，将XML文件转换为按日期排序的XML文件如下所示：

    </Root>

我希望将其按OrderDate排序，但是我不知道该怎么做。 谁能给我任何建议？

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Order记录的列表

如果要将其存储在文件中，请使用“记录”作为数据源重新创建XML文件。

我使用了Linq XML。 我认为添加到新的XML元素比对原始XML元素进行排序更容易 

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 =
