如何从 json 字符串 asp.net mvc Newtonsoft.json 获取对象列表

Question

我正在尝试将 JSON 字符串转换为对象列表，但出现错误

无法将当前 JSON 对象反序列化为 List 类型，因为该类型需要 JSON 数组才能正确反序列化。

我检索了 json，它看起来像这样

     {
    "totalCount": 4,
    "items": [
        {
            "Tarih": "10-10-2019",
            "TP_DK_SAR_A": "1.5538",

        }
    ]
}

您好，我解决了这个问题并使用了两种不同的方法；

1-)
     ExchangeRateGetViewModel CompanyInfoData = Newtonsoft.Json.JsonConvert.DeserializeObject<ExchangeRateGetViewModel>(jsonResultString);

2-)
var o = JsonConvert.DeserializeObject<JObject>(jsonResultString);
            var h = o.Value<JArray>("items")
                .ToObject<List<ExchangeRateGetListViewModel>>();
