将JSON转换为C＃复杂对象

Question

我在C＃中具有此结构，我想创建可以成功转换为JSON的JSON，以便可以轻松地在JS逻辑中发现我的错误。

public class Tree
{
        public Root Root { get; set; }
        public Tree()
        {}
}

public class Root : Node
{
        public Root(int _id, int _fk, string _name, string _code, List<Node> _children, List<Item> _leaves)
            : base(_id, _fk, _name, _code, _children, _leaves)
        {
        }

        public Root()
        { }
}

public abstract class Node
{
        public int? ID { get; set; }
        public int? FK { get; set; }
        public string Name { get; set; }
        public string Code { get; set; }
        public List<Node> children { get; set; }
        public List<Item> leaves { get; set; }

        public Node(int? _id, int? _fk, string _name, string _code, List<Node> _children, List<Item> _leaves)
        {
            ID = _id;
            FK = _fk;
            Name = _name;
            Code = _code;
            children = _children;
            leaves = _leaves;
        }
        public Node ()
        {}
}

public class Item
{
        public string Code { get; set; }
        public string Desc { get; set; }
        public string Uom { get; set; }
        public float? Measurements { get; set; }
        public int? FK { get; set; }
        public int? Tier { get; set; }
        public bool IsADPresent { get; set; }
}

以及我尝试提供的命令JsonConvert.DeserializeObject<Tree>(tree)的最基本的JSON是：

"{\"Tree\":{\"Root\":{\"children\":[],\"leaves\":[],\"FK\":1,\"ID\":1,\"Name\":\" LOGISTICS\",\"Code\":\"PT01\"}}}"

但是我在Tree中仍然为null；更不用说当JSON变得毛茸茸的时候了（树可以拥有第5个孙代）。

谢谢

Answer 1

您应该从JSON中删除Tree，因为Tree是目标类型，并且不需要包含在JSON中。

{
    "Root": {
        "children": [],
        "leaves": [],
        "FK": 1,
        "ID": 1,
        "Name": " LOGISTICS",
        "Code": "PT01"
    }
}

Answer 2

在json中省略Tree属性。

为了进行测试，您可以将树实例序列化为json以查看其外观。大概是这样{"Root":{"children":[],"leaves":[],"FK":1,"ID":1,"Name":" LOGISTICS","Code":"PT01"}}
