JSON使用C#中的嵌套列表进行反序列化

本文关键字：列表 反序列化 嵌套 使用 JSON | 更新日期: 2023-09-27 17:58:23

我正在C#中序列化和反序列化Dictionary。我的数据结构是：

    public class DataField
{
    private string _Name;
    public string Name
    {
        get { return _Name; }
        set
        {
            _Name = value;
        }
    }
    private string _Label;
    public string Label
    {
        get { return _Label; }
        set
        {
            _Label = value;
        }
    }
    private ControlType _TypeOfControl;
    public ControlType TypeOfControl
    {
        get { return _TypeOfControl; }
        set { _TypeOfControl = value; }
    }
    private int _Width;
    public int Width
    {
        get { return _Width; }
        set
        {
            _Width = value;
        }
    }
    private DataType _DataType;
    public DataType DataType
    {
        get { return _DataType; }
        set { _DataType = value; }
    }
    private Control _ControlAccessor;
    public Control ControlAccessor
    {
        get { return _ControlAccessor; }
        set { _ControlAccessor = value; }
    }

    private Type _ControlType;
    public Type ControlType
    {
        get { return _ControlType; }
        set { _ControlType = value; }
    }
    private List<KeyValuePair<string, string>> _Items;
    public List<KeyValuePair<string, string>> Items
    {
        get { if (_Items == null) _Items = new List<KeyValuePair<string, string>>(); return _Items; }
        set { _Items = value; }
    }

我正在序列化的对象是Dictionary<string, DataField>()。我正在做：

JavaScriptSerializer js = new JavaScriptSerializer();
string str = js.Serialize(ht);`

我得到的字符串是正确的：

{"Title" {"Name":"Title","Label":null,"TypeOfControl":0,"Width":200,"DataType":0,"ControlAccessor":null,"ControlType":null,"Items":[]}
,"Price":{"Name":"Price","Label":null,"TypeOfControl":0,"Width":100,"DataType":1,"ControlAccessor":null,"ControlType":null,"Items":[]}
,"Category":{"Name":"Category","Label":null,"TypeOfControl":0,"Width":100,"DataType":1,"ControlAccessor":null,"ControlType":null,"Items":[]}
,"Test":{"Name":"Test","Label":null,"TypeOfControl":0,"Width":100,"DataType":1,"ControlAccessor":null,"ControlType":null,"Items":[]}
,radioGeo":{"Name":"radioGeo","Label":null,"TypeOfControl":3,"Width":0,"DataType":0,"ControlAccessor":null,"ControlType":null
,"Items":[{"Key":"Position","Value":"posit"},{"Key":"Area","Value":"area"},{"Key":"Area","Value":"area"}]}
,"htmled":{"Name":"htmled","Label":null,"TypeOfControl":2,"Width":170,"DataType":0,"ControlAccessor":null,"ControlType":null,"Items":[]}}";

当我对它进行反序列化时，几乎所有内容都是正确的。问题在于嵌套列表。虽然它们序列化得很好，但当我把它放回一起时，列表是空的。

有什么建议吗？

JSON使用C#中的嵌套列表进行反序列化

我假设您使用的是Json.net我在工作中遇到了同样的问题，列表的反序列化不完整。此错误已添加到项目的问题跟踪器中。我们找到的解决方法是不将列表作为对象中的最后一个var。

希望这能在等待补丁时对你有所帮助。
