            ]
        }

......它一直在继续......

如何将此JSON反序列化为名为Element的类？如果您愿意，可以忽略“wiki”字段。

我尝试了什么：

Table t = JsonConvert.DeserializeObject<Table> (lines);

class Table {
    public string wiki;
    public Element[] element;
}

class Element {
    public string group, name, small;
    public int position, numer;
    public double molar;
    public int[] electrons;
}

我无法让它发挥作用。

Answer 1

你在班级成员中有几个错别字，但关键部分如下：

看一下JSON文档的开头：

{
    "table": [

它实质上意味着您需要一个名为table的数组属性的对象。

正确的课程是：

class Root
{
    public Table[] table;
}

class Table
{
    public string wiki;
    public Element[] elements;
}

class Element
{
    public string group, name, small;
    public int position, number;
    public double molar;
    public int[] electrons;
}

和反序列化代码：

var root = JsonConvert.DeserializeObject<Root>(lines);

Answer 2

Parent = JsonConvert.DeserializeObject<Parent> (lines);

class Parent {
    public Mid[] table;
}

class Mid {
    public string wiki;
    public Element[] elements;
}

class Element {
    public string group, name, small;
    public int position, numer;
    public double molar;
    public int[] electrons;
}

使用JSON.NET在C＃中反序列化此JSON
