JSON序列化列表>

如果您使用Newtonsoft Json.NET库，则可以执行以下操作。

定义一个转换器，以所需的方式写入键/值对的列表：

class MyConverter : JsonConverter{    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)    {        List<KeyValuePair<string, object>> list = value as List<KeyValuePair<string, object>>;        writer.WriteStartArray();        foreach (var item in list)        { writer.WriteStartObject(); writer.WritePropertyName(item.Key); writer.Writevalue(item.Value); writer.WriteEndObject();        }        writer.WriteEndArray();    }    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)    {        // TODO...    }    public override bool CanConvert(Type objectType)    {        return objectType == typeof(List<KeyValuePair<string, object>>);    }}

然后使用转换器：

var keyValuePairs = new List<KeyValuePair<string, object>>         {  new KeyValuePair<string, object>("one", 1),  new KeyValuePair<string, object>("two", 2),  new KeyValuePair<string, object>("three", 3)         };JsonSerializerSettings settings = new JsonSerializerSettings { Converters = new [] {new MyConverter()} };string json = JsonConvert.SerializeObject(keyValuePairs, settings);

这产生

[{"one":1},{"two":2},{"three":3}]
