C# 如何在Xml中获取当前属性值，并使用当前属性值检索下一个节点值？

您只需要创建一个列表对象。使用XMLLINQ是最好的方法

using System.Xml.XPath;

namespace ConsoleApplication14
{
    interface IQuestion
    {
        void Question1();
        void Next();

    }
    class Question : IQuestion
    {
         string BuildXpathQuery(int c)
        {

            string part1 = @"questions/question[@num='";
            string part2 = @"']";
            string MyQuery = part1 + c + part2;
            return MyQuery;

        }
        public void Question1()
        {
            XmlDocument doc = new XmlDocument();
            doc.Load("C:\\Users\\Murari\\Documents\\Visual Studio 2015\\Projects\\ConsoleApplication14\\ConsoleApplication14\\XMLFile1.xml");


            XmlNode xnList = doc.SelectSingleNode(BuildXpathQuery(1));
            if (xnList != null)
            {
                Console.WriteLine(xnList.InnerXml);
                Console.ReadKey();
            }
        }
