这是我的XML结构，我需要一个C#程序来添加、编辑和删除N级别的元素。

<root>
  <TopLevelMenu ID="&amp;File">
    <MenuItem ID="New" OnClick="_New" />
    <MenuItem ID="Open" OnClick="_Open" />
    <MenuItem ID="-" />
    <MenuItem ID="Close" OnClick="_Close" />
    <MenuItem ID="-" />
    <MenuItem ID="E&amp;xit" OnClick="_Exit" />
  </TopLevelMenu>
  <TopLevelMenu ID="&amp;Edit">
    <MenuItem ID="Undo" OnClick="_Undo" />
    <MenuItem ID="-" />
    <MenuItem ID="Cut" OnClick="_Cut" />
    <MenuItem ID="Copy" OnClick="_Copy" />
    <MenuItem ID="Paste" OnClick="_Paste" />
    <MenuItem ID="-" />
    <MenuItem ID="Options">
      <MenuItem ID="Sub Menu Item">
        <MenuItem ID="Sub Sub Menu Item" />
      </MenuItem>
    </MenuItem>
  </TopLevelMenu>
</root>

试试这个递归代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication34
{
    class Program
    {
        static void Main(string[] args)
        {
            string input =
            "<root>'n" +
              "<TopLevelMenu ID='"Imports&amp;FileImports'">'n" +
                "<MenuItem ID='"ImportsNewImports'" OnClick='"Imports_NewImports'"/>'n" +
                "<MenuItem ID='"ImportsOpenImports'" OnClick='"Imports_OpenImports'"/>'n" +
                "<MenuItem ID='"Imports-Imports'" />'n" +
                "<MenuItem ID='"ImportsCloseImports'" OnClick='"Imports_CloseImports'"/>'n" +
                "<MenuItem ID='"Imports-Imports'"/>'n" +
                "<MenuItem ID='"ImportsE&amp;xitImports'" OnClick='"Imports_ExitImports'"/>'n" +
              "</TopLevelMenu'n>" +

                "</MenuItem>'n" +
              "</TopLevelMenu>'n" +
            "</root>'n";
            XDocument doc = XDocument.Parse(input);
            var results = doc.Descendants("TopLevelMenu").Elements("MenuItem").Select(y => GetMenu(y)).ToList();
        }
        static object GetMenu(XElement element)
        {
            if (!element.HasElements)
            {
                return element.Attribute("ID").Value;
            }
            else
            {
                return (new { id = element.Attribute("ID").Value, child = GetMenu(element.Element("MenuItem"))});
            }
        }
    }
}
