为什么我的内部对象属性名称不使用驼峰式大小写？

我在解决序列化问题。

我在SQL表中有一列，其中包含一个pascal大小写的JSON片段：

{
  "HistoryOpertions": [
    {
      "OperationTitle": "Titre Op",
      "OperationDetails": "Details Op"
    },
    {
      "OperationTitle": "2",
      "OperationDetails": "Op 2"
    },
    {
      "OperationTitle": "by Ol",
      "OperationDetails": "Test",
      "OperateurName": "Olivier Matrot",
      "TimeStamp": 637100138608377997
    }
  ],
  "TimestampLastModification": "2019-11-29T11:09:16.1621275Z",
  "AlertInstructions": [
    {
      "InstructionId": 1,
      "OperateurName": null,
      "CheckPoint": false,
      "TimeStamp": null
    }
  ],
  "AlertTitle": "Alerte safe protect",
  "LiftingDoubtId": 2,
  "SupportId": 3
}

我有以下代码来解析此片段，进行一些修改，然后创建一个新对象并将其序列化回字符串。这次我希望属性名称采用驼峰式：

var json = JObject.Parse(existingAlertDetailEntity.SafeProtectCustomInfo ?? "{}");

JArray alertInstructions = json["AlertInstructions"] as JArray;
foreach (var instruction in alertInstructions)
{
    if (instruction[nameof(AlertInstruction.InstructionId)].ToObject<int>() == model.InstructionId)
    {
        bUpdated = true;
        instruction[nameof(AlertInstruction.TimeStamp)] = model.Status ? DateTime.UtcNow.Ticks : (long?)null;
        instruction[nameof(AlertInstruction.OperateurName)] = model.Status ? user.DisplayName : null;
        instruction[nameof(AlertInstruction.CheckPoint)] = model.Status;
        break;
    }
}
var jsonSerializer = new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore,ContractResolver = new CamelCasePropertyNamesContractResolver() };
string jsonToBeReturned = JsonConvert.SerializeObject(
    new {
        model.AlertId,
        AlertInstructions = JArray.FromObject(
        json["AlertInstructions"],
        JsonSerializer.Create(new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver(),
        })),
    }, jsonSerializer);

结果如下：

{
   "alertId":1295041,
   "alertInstructions":[
      {
         "InstructionId":1,
         "TimeStamp":637111473877506411,
         "OperateurName":"Olivier Matrot",
         "CheckPoint":true
      },
      {
         "InstructionId":2,
         "TimeStamp":637112167087671938,
         "OperateurName":"Olivier Matrot",
         "CheckPoint":true
      }
   ]
}

我们可以看到alertInstructions数组仍然包含Pascal Cased属性名称。

您可以使用来反序列化JSON ExpandoObject，对其进行修改并将其序列化为字符串。

var settings = new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore,ContractResolver = new CamelCasePropertyNamesContractResolver() };
dynamic json = JsonConvert.DeserializeObject<ExpandoObject>(JSON);

// modify your structure here...
json.AlertInstructions[0].TimeStamp = 1234;

var jsonToBeReturned = JsonConvert.SerializeObject(new {
    AlertId = 42,
    AlertInstructions  = json.AlertInstructions
}, Formatting.Indented, settings);
