Question

我试图反序列化json对象。它在某一点上工作正常。我有一个Area对象，它包含一个Zone对象数组。

{
  "Area":{
    "id": "0",
    "type": "area",
    "size": {
      "x": 4.5,
      "y": 4.5,
      "z": 4.5
    },
    "position": {
      "x": 0,
      "y": 0,
      "z": 0
    },
    "rotation": {
      "x": 0,
      "y": 0,
      "z": 0
    },
    "zones": [
      {
        "id": "001",
        "type": "zone",
        "size": {
          "x": 1,
          "y": 1,
          "z": 1
        },
        "position": {
          "x": 1,
          "y": 0,
          "z": 1
        },
        "rotation": {
          "x": 0,
          "y": 0,
          "z": 0
        }
      },
      {
        "id": "002",
        "type": "zone",
        "size": {
          "x": 1,
          "y": 1,
          "z": 1
        },
        "position": {
          "x": 3,
          "y": 0,
          "z": 1
        },
        "rotation": {
          "x": 0,
          "y": 0,
          "z": 0
        }
      }
    ]
  }
}

Area类型反序列化很好，但是，我希望区域数组反序列化为List<Zone>。我怎样才能做到这一点？

string jsonString = r.ReadToEnd();
JavaScriptSerializer jss = new JavaScriptSerializer();
Area area = jss.Deserialize<Area>(jsonString);

public class Area : AirObject3D
{
    public List<Zone> zones;
    public List<TouchPoint> touchPoints;
    public Area()
    {
        this.size.X = 4.5;
        this.size.Z = 4.5;
    }
}

您只需要正确设置合同即可。为了反序列化列表，您只需将属性类型设置为List<Zone>（您也可以使用Zone[]反序列化为数组。）

您的合同可能如下所示：

public class Root
{
    public Area Area { get; set; }
}
public class Area
{
    [XmlElement("id")]
    public string Id { get; set; }
    [XmlElement("type")]
    public string Type { get; set; }
    [XmlElement("size")]
    public Coordinate Size { get; set; }
    [XmlElement("position")]
    public Coordinate Position { get; set; }
    [XmlElement("rotation")]
    public Coordinate Rotation { get; set; }
    [XmlElement("zones")]
    public List<Zone> Zones { get; set; }
}
public class Zone
{
    [XmlElement("id")]
    public string Id { get; set; }
    [XmlElement("type")]
    public string Type { get; set; }
    [XmlElement("size")]
    public Coordinate Size { get; set; }
    [XmlElement("position")]
    public Coordinate Position { get; set; }
    [XmlElement("rotation")]
    public Coordinate Rotation { get; set; }
}
public class Coordinate
{
    [XmlElement("x")]
    public float X { get; set; }
    [XmlElement("y")]
    public float Y { get; set; }
    [XmlElement("z")]
    public float Z { get; set; }
}

请注意使用XmlElementAttribute来确保将小写属性正确地反序列化为大写的C＃属性（因为属性应按约定大写）。

在您的数据上使用这样的方法，它可以正确填充所有对象：

JavaScriptSerializer jss = new JavaScriptSerializer();
Root root = jss.Deserialize<Root>(jsonString);

你的对象图应该看起来像 -

public class Size
{
    public double x { get; set; }
    public double y { get; set; }
    public double z { get; set; }
}

public class Position
{
    public int x { get; set; }
    public int y { get; set; }
    public int z { get; set; }
}

public class Rotation
{
    public int x { get; set; }
    public int y { get; set; }
    public int z { get; set; }
}

public class Zone
{
    public string id { get; set; }
    public string type { get; set; }
    public Size size { get; set; }
    public Position position { get; set; }
    public Rotation rotation { get; set; }
}

public class Area
{
    public string id { get; set; }
    public string type { get; set; }
    public Size size { get; set; }
    public Position position { get; set; }
    public Rotation rotation { get; set; }
    public List<Zone> zones { get; set; }
}

public class RootObject
{
    public Area Area { get; set; }
}

var o = JsonConvert.DeserializeObject<RootObject>("json");
