C# 使用自定义Json序列化程序创建集合

这段代码是ASP.NETWebAPI控制器的一部分，在将其发送到UI之前，我需要修改最终Json中的某些值

我当前的代码如下所示：

// Web API controller

public partial class ViewRController
        {
       [HttpGet]
            public DataMapList FetchEmployeeDataList()
            {
                DataMapList returnDataMapList = new DataMapList();

                return (returnDataMapList);
            }
        }

// Type definition and details

    [JsonObject]
        [JsonConverter(typeof(DataMapListSerializer))]
        public class DataMapList
        {
            public List<Dictionary<object, object>> employeeSalaryMappingList = null;

            public DataMapList()
            {
                employeeSalaryMappingList = new List<Dictionary<object, object>>();
                employeeSalaryMappingList.Add(new Dictionary<object, object>());

                employeeSalaryMappingList[0].Add(1, 10000);
                employeeSalaryMappingList[0].Add(2, 13000);
                employeeSalaryMappingList[0].Add(3, 15000);

                employeeSalaryMappingList.Add(new Dictionary<object, object>());

                employeeSalaryMappingList[1].Add(4, 9000);
                employeeSalaryMappingList[1].Add(5, 12000);
                employeeSalaryMappingList[1].Add(6, 11000);
            }
        }

// Custom Json serializer

public class DataMapListSerializer : JsonConverter
    {
        public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
        {
            var employeeSalaryDataMapList = value as DataMapList;
            var employeeSalaryMappingList = employeeSalaryDataMapList.employeeSalaryMappingList;


            writer.WriteStartObject();
            foreach (var employeeSalaryMappingDictionary in employeeSalaryMappingList)
            {
                writer.WritePropertyName("ED");
                writer.WriteStartObject();

                foreach (var keyValuePair in employeeSalaryMappingDictionary)
                {
                    writer.WritePropertyName("ID-" + keyValuePair.Key);
                    serializer.Serialize(writer, keyValuePair.Value);
                }

                writer.WriteEndObject();
            }

            writer.WriteEndObject();
        }       

        public override bool CanConvert(Type objectType)
        {
            return typeof(DataMapList).IsAssignableFrom(objectType);
        }
    }

但是，我希望得到以下结果，因为我正在序列化集合.Net列表类型.Net集合

[ 
   "ED": { "ID-1": 10000, "ID-2": 13000, "ID-3": 15000 }, 
  "ED": { "ID-4": 9000, "ID-5": 12000, "ID-6": 11000 } 
]

事实上，当我尝试在中验证时，当前结果显示了有效的Json，但终止了其中的一部分，因此它将以下内容显示为有效的Json，但这只是一种转移

{
    "ED": {
        "ID-4": 9000,
        "ID-5": 12000,
        "ID-6": 11000
    }
}

我已尝试替换writer.WriteStartObject；和writer.WriteEndObject；作者：WriteStartaray；和作家。写达雷；，在第一个foreach循环之前遍历类型中的列表，但这会导致异常，因此没有帮助

"exceptionMessage": "Token StartArray in state ObjectStart would result in an invalid JSON object. Path '

任何解决问题的建议，如果您需要任何澄清，请告诉我，在中，名称-值对必须位于对象{}内；它们不能直接位于数组[]内。因此，您尝试创建的这个JSON无效，这就是为什么会出现异常：

[ 
   "ED": { "ID-1": 10000, "ID-2": 13000, "ID-3": 15000 }, 
   "ED": { "ID-4": 9000, "ID-5": 12000, "ID-6": 11000 } 
]

为了使其成为有效集合，每个ED名称-值对必须包装在如下对象中：

[ 
   { 
      "ED": { "ID-1": 10000, "ID-2": 13000, "ID-3": 15000 } 
   }, 
   { 
      "ED": { "ID-4": 9000, "ID-5": 12000, "ID-6": 11000 } 
   }
]

一旦您看到这一点，解决方案就会变得清晰：在DataMapListSerializer中，您需要在循环外部使用writer.WriteStarray和writer.WriteEndArray，并且需要在循环内部添加writer.WriteStarObject和writer.WriteEndObject

    writer.WriteStartArray();

    foreach (var employeeSalaryMappingDictionary in employeeSalaryMappingList)
    {
        writer.WriteStartObject();

            writer.WritePropertyName("ED");
            writer.WriteStartObject();

            foreach (var keyValuePair in employeeSalaryMappingDictionary)
            {
                writer.WritePropertyName("ID-" + keyValuePair.Key);
                serializer.Serialize(writer, keyValuePair.Value);
            }

            writer.WriteEndObject();

        writer.WriteEndObject();
    }

    writer.WriteEndArray();

Fiddle:

{data:[{ID44:2，ID43:Block}，{ID44:1，ID43:Train}}}这将是一个有效的Json，我已经验证过了。您是对的，我需要将所有内容包装在{}中，以使其成为有效的Json。所以我需要做的就是把所有东西都包装在writer.WriteStartObject中；writer.WriteEndObject；在链接处修改了代码，感谢您提供的清晰性

    writer.WriteStartArray();

    foreach (var employeeSalaryMappingDictionary in employeeSalaryMappingList)
    {
        writer.WriteStartObject();

            writer.WritePropertyName("ED");
            writer.WriteStartObject();

            foreach (var keyValuePair in employeeSalaryMappingDictionary)
            {
                writer.WritePropertyName("ID-" + keyValuePair.Key);
                serializer.Serialize(writer, keyValuePair.Value);
            }

            writer.WriteEndObject();

        writer.WriteEndObject();
    }

    writer.WriteEndArray();
