在C＃

Question

我将Windows通用应用程序中的C＃对象序列化为JSON，使用custom Converter命名对象中description字符串后面的节点。而不是

{  
   "description":"upper-left",
   "value":23
},
{  
   "description":"upper-right",
   "value":24
}

我得到了

[
   {  
      "upper-left":23
   },
   {  
      "upper-right":24
   }
]

这适用于我，使用转换器的改编版本。但是，我想在单个节点中收集这些键：值对，如下所示：

{  
   "upper-left":23,
   "upper-right":24
}

我怎样才能做到这一点？

Answer 1

I created a custom converter for this -

internal class MyObjectJsonConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return true;
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        var dataList = value as List<RootObject>;

        writer.WriteStartObject();
        foreach (var data in dataList)
        {   
            writer.WritePropertyName(data.description);
            writer.WriteValue(data.value);
        }
        writer.WriteEndObject();
    }
}

where -

public class RootObject
{
    public string description { get; set; }
    public int value { get; set; }
}


var s = JsonConvert.SerializeObject(new List<RootObject> {
            new RootObject
            {
                description = "upper-left",
                value = 23
            },
            new RootObject
            {
                description = "upper-right",
                value = 24
            }
        }, jss);
