jsontosharp生成以下的类，不会使用~

原json
{
    "name":"key_word",
    "children":
    [
        {
            "name": "lisi",
            "children": 
            [
                {
                    "name":"age",
                     "children": 
                        [


{"name":"25"}
                        ]
                },
                {
                     "name": "grade",
                     "children": 
                        [


{"name": "100"}
                        ]
                }
            ]
        }
    ]
}



生成类

public class Child3
{
    public string name { get; set; }
}

public class Child2
{
    public string name { get; set; }
    public List<Child3> children { get; set; }
}

public class Child
{
    public string name { get; set; }
    public List<Child2> children { get; set; }
}

public class RootObject
{
    public string name { get; set; }
    public List<Child> children { get; set; }
}
