如何獲取Xml中的當前屬性值並使用當前屬性值檢索下一個節點值？

Question

<?xml version="1.0" encoding="utf-8" ?> 
    <questions> 
     <question num="1">Employees should be involved in setting their goals.</question> 
     <question num="2">Most people resists change.</question> 
     <question num="3">Manager should guide rather control.</question> 
     <question num="4">Average person is easily decieved.</question> 
    </questions> 

如何將當前屬性值設置爲變量i，當調用next（）方法時使用此當前屬性i，它應該檢索下一個節點值（例如，如果當前屬性值爲1時（）被稱爲它應該檢索第二個節點的值，當再次調用next（）它應該檢索第三個屬性值）使用System.Xml？

我試圖使用Xpath檢索第一個節點值，但我不知道如何將當前屬性值設置爲變量，然後使用變量移動到下一個節點值。以下是我嘗試過的代碼。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Xml; 
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(); 
      } 
     } 

     public void Next() 
     { 

     }  
    } 


    class Program 
    { 
     static void Main(string[] args) 
     { 
      IQuestion ques = new Question(); 
      ques.Question1(); 
      ques.Next(); 


     } 
    } 
}

您簡單需要創建一個列表<>對象。使用XML Linq是最好的方法

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

namespace ConsoleApplication1 
{ 
    class Program 
    { 
     const string FILENAME = @"c:\temp\test.xml"; 
     static void Main(string[] args) 
     { 
      XDocument doc = XDocument.Load(FILENAME); 

      var xnList = doc.Descendants("question").Select(x => new 
      { 
       num = (int)x.Attribute("num"), 
       text = x.Value 
      }).ToList(); 

      foreach (var question in xnList) 
      { 
      } 
     } 
    } 
}
