从XML文件中读取一个数组 [英] Reading an array from an XML file

问题描述

目前II得到这个：

class robot
{
    Configuratie config = new Configuratie();
    short[,] AlleCoordinaten = new short[3, 6] 
    {
        {1,2,3,4,5,6},
        {6,5,4,3,2,1},
        {2,3,4,5,6,7}
    };
}

不过，我想提出一个XML的文件，数组，所以这是我的尝试：

But I want to put that array in a XML-file, so this is what I tried:

class robot
{
private static XDocument xdoc = XDocument.Load("configuratie.xml");

    public Robot()
    {
        short[,] AlleCoordinaten = new short[3, 6];
        for (int i = 0; i < 3; i++)
        {
            for (int j = 0; j < 6; j++)
            {
                AlleCoordinaten[i, j] = GetPositionValue("position" + (i + 1), j);
            }
        }
    }
    public static short GetPositionValue(string position,int index)
   {
       return (short)xdoc.Descendants(position).Skip(index).First();
   }
    private void methode2()
    {
    GoTo[0] = new Position();
    for (short a=0 ; a<10 ; a++)
       {
       GoTo[0].degrees[0] = AlleCoordinaten[a,0];
       GoTo[0].degrees[1] = AlleCoordinaten[a,1];
       GoTo[0].degrees[2] = AlleCoordinaten[a,2];
       GoTo[0].degrees[3] = AlleCoordinaten[a,3];
       GoTo[0].degrees[4] = AlleCoordinaten[a,4];
       GoTo[0].degrees[5] = AlleCoordinaten[a,5];
       //here it tells me The name 'AlleCoordinaten' does not exist in the currect context 
       }
    }
}

配置文件：

    class Configuratie
    {
        private XDocument xdoc;

        public Configuratie()
        {
            xdoc = XDocument.Load("configuratie.xml");
        }
    public int GetIntConfig(string desc1, string desc2)
    {
        int value = 0;
        if (string.IsNullOrEmpty(desc1))
        {
            value = 0;
        }
        if (!string.IsNullOrEmpty(desc1) && !string.IsNullOrEmpty(desc2))
        {
            foreach (XElement node in xdoc.Descendants(desc1).Descendants(desc2))
            {
                value = Convert.ToInt16(node.Value);
            }
        }
        if (!string.IsNullOrEmpty(desc1) && string.IsNullOrEmpty(desc2))
        {  
            foreach (XElement node in xdoc.Descendants(desc1))
            {
                value = Convert.ToInt16(node.Value);
            }
        }
        return value;
        }
    }

XML文件：

<robot>
<position1>1</position1>
<position1>2</position1>
<position1>3</position1>
<position1>4</position1>
<position1>5</position1>
<position1>6</position1>
etc...
<position3>7</position3>
</robot>

它仍然心不是工作，可你们帮助我，我做错了什么，也许举一个例子。

It still isnt working, could you guys help me with what I did wrong and maybe give an example.

推荐答案

试试这个方法：

public static short GetPositionValue(string position,int index)
{
    return (short)xdoc.Descendants(position).Skip(index).First();
}

和与循环填充您的数组：

And populate your array with for loop:

下面是完整的code：

Here is the full code:

class robot
{
      private static XDocument xdoc = XDocument.Load("configuratie.xml");

      short[,] AlleCoordinaten = new short[3, 6];
      for (int i = 0; i < 3; i++)
      {
         for (int j = 0; j < 6; j++)
         {
              AlleCoordinaten[i, j] = GetPositionValue("position" + (i+1), j);
         }
      }

      public static short GetPositionValue(string position,int index)
      {
           return (short)xdoc.Descendants(position).Skip(index).First();
      }

}

请注意：更改您 XDOC 定义：

private XDocument xdoc;

要：

private static XDocument xdoc;
