反序列化列表< ArrayList的>目的 [英] Deserialize List<ArrayList> object

问题描述

我试图反序列化XML一个对象，但我被陷在一种情况。任何人都可以请帮我在这里。

I am trying to de-serialize a XML to object but I am getting stuck at one situation. Can anyone please help me out here.

XML：

<?xml version="1.0" ?>
<Level>
  <Warp_Blocks>
        <Warp_Block>
            <Block row="7" col="7" />
            <Block row="2" col="7" />
        </Warp_Block>
        <Warp_Block>
            <Block row="4" col="4" />
            <Block row="3" col="7" />
        </Warp_Block>
  </Warp_Blocks>
</Level>

代码：

Code:

  [XmlRoot("Level")]
   public class LData
    {
        [XmlArray("Warp_Blocks")]
        [XmlArrayItem("Warp_Block",typeof(WarpBlock),IsNullable = false)]
        public List<WarpBlock> WarpBlocks;
    }
   public class LBlock
   {
      [XmlAttribute("row")]
      public int row;
      [XmlAttribute("col")]
      public int col;
   }
   public class WarpBlock
   {
      [XmlArray("Warp_Block")]
      [XmlArrayItem("Block",typeof(LBlock),IsNullable= false)]
      public List<LBlock> WarpBlocks;

      public WarpBlock()
      {
            WarpBlocks = new List<LBlock>();
      }
   }

我能够反序列化到一个级别，即我得到的项目对象的名单，但个别项目的对象不包含块对象的列表。我在做什么错在这里？

I am able to de-serialize to one level i.e. I get a List of Item objects but the individual Item objects don't contain the List of Block objects. What am I doing wrong here?

推荐答案

您LDATA类改成这样：

Change your LData class to this:

[XmlRoot("Level")]
public class LData
{
    [XmlElement("Warp_Blocks")]
    public List<WarpBlock> WarpBlocks;
}

编辑：

口不知道为什么它不看你的第二个Warp_Block。唯一可能的原因，我想可能是你正在做的事情比你曾经参与过这个问题还有什么。下面是完整的例子：

I don't know why it is not reading your second Warp_Block. The only possible reason I think can be that you are doing something else than what you have posted in the question. Here is the full example:

[XmlRoot("Level")]
public class LData
{
    [XmlElement("Warp_Blocks")]
    public List<WarpBlock> WarpBlocks;
}
public class LBlock
{
    [XmlAttribute("row")]
    public int row;
    [XmlAttribute("col")]
    public int col;
}
public class WarpBlock
{
    [XmlArray("Warp_Block")]
    [XmlArrayItem("Block", typeof(LBlock), IsNullable = false)]
    public List<LBlock> WarpBlocks;

    public WarpBlock()
    {
        WarpBlocks = new List<LBlock>();
    }
}
public class Program
{
    public static void Main()
    {
        string test =
            "<?xml version=\"1.0\" ?>" +
            "<Level>" +
            "  <Warp_Blocks>" +
            "        <Warp_Block>" +
            "            <Block row=\"7\" col=\"7\" />" +
            "            <Block row=\"2\" col=\"7\" />" +
            "        </Warp_Block>" +
            "        <Warp_Block>" +
            "            <Block row=\"4\" col=\"4\" />" +
            "            <Block row=\"3\" col=\"7\" />" +
            "        </Warp_Block>" +
            "  </Warp_Blocks>" +
            "</Level>";

        byte[] byteArray = Encoding.ASCII.GetBytes(test);
        MemoryStream stream = new MemoryStream(byteArray);

        XmlSerializer s = new XmlSerializer(typeof (LData));
        LData data = (LData) s.Deserialize(stream);

        foreach (var a in data.WarpBlocks)
            foreach (var b in a.WarpBlocks)
                Console.WriteLine(b.row + ", " + b.col);

        Console.ReadKey();
    }
}

它正确地输出这样的：

It correctly outputs this:

7, 7
2, 7
4, 4
3, 7
