      "AllowPrintCostEstimate": false,
      "CostEstimateCount": 0,
      "AllowMultipleFaxNumbers": false
    }
  ]
}

我尝试通过创建一个具有所有属性的对象 SenderInfo 来反序列化所有内容并尝试

var result = JsonConvert.DeserializeObject<List<SenderInfo>>(jsonString);

但我得到了 Newtonsoft.Json.JsonSerializationException。因为我不需要所有数据，所以我也更愿意只反序列化某些属性。我确定一定有办法实现这一点，也许是通过 StringReader 或其他方式？

感谢任何想法。

无论您在 SenderInfo 中有什么，List<SenderInfo>> 都不代表您的 json 结构，请尝试这样的操作：

public class SendersContainer 
{
    [JsonProperty("Senders")]
    public List<SenderInfo> Senders { get; set; }
}

var result = JsonConvert.DeserializeObject<SendersContainer>(jsonString);
