c# - 如何在不在 C# 中定义模型类的情况下向现有 json 添加新属性？

Question

{
    "version": "15.1",
    "count": 8,
    "data": [
        {
            "furit_items": [
                {
                    "price": 12.6,
                    "base_price": 6.59,
                    "text": "banana",
                    "product_id": "1234",
                    "product_name": "banana",
                    "quantity": 1
                }
            ],
            "product_sub_total": 12.6,
            "product_total": 12.6,
            "shipments": []
        }
    ]
}

这是我通过服务获取的 json 数据。

是否可以在“furit_items”对象下添加新属性 {"quality":"good"}？

试试这个:

dynamic original = JsonConvert.DeserializeObject(json, typeof(object));
original.data[0].furit_items[0].quality = good;
var modifiedJson = JsonConvert.SerializeObject(original , Formatting.Indented);
