  }

如果你看到，根名称就像

1000
1001
1002
1003

我想将它反序列化为一个对象。这些数字下面的结构是相同的。

有人可以建议我如何为此生成类吗？并使用 NewtonSoft 进行反序列化？

请注意，我无法更改 JSON，它的文件非常大(大约 16MB)。

Answer 1

有一个非常酷的功能叫做将 JSON 作为类粘贴:

参见 here .注意:这是 originally came with 的一项功能visual studio 扩展 web essentials。因此，根据您的 VS 版本，您可能需要 install this extension .

如果您粘贴第一个根节点，它会生成这些类:

public class Rootobject
{
    public _1000 _1000 { get; set; }
}

public class _1000
{
    public int id { get; set; }
    public string name { get; set; }
    public Path_From_Root[] path_from_root { get; set; }
    public Children_Categories[] children_categories { get; set; }
    public bool attributes_required { get; set; }
    public int max_pictures_per_item { get; set; }
    public int max_title_length { get; set; }
    public object max_price { get; set; }
    public object min_price { get; set; }
    public bool listing_allowed { get; set; }
}

public class Path_From_Root
{
    public int id { get; set; }
    public string name { get; set; }
}

public class Children_Categories
{
    public int id { get; set; }
    public string name { get; set; }
}

这可能是您需要的。也许稍微改进一下。
