具有难以理解的结构，您可以使用以下自定义转换器之类的工具来执行所需的操作：
[TestMethod]public void Conversion(){ var obj = new DualDate() { DateOne = new DateTime(2013, 07, 25), DateTwo = new DateTime(2013, 07, 25) }; Assert.AreEqual("{"DateOne":"07.25.2013","DateTwo":"2013-07-25T00:00:00"}", JsonConvert.SerializeObject(obj, Formatting.None, new DualDateJsonConverter()));}class DualDate{ public DateTime DateOne { get; set; } public DateTime DateTwo { get; set; }}class DualDateJsonConverter : JsonConverter{ public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { JObject result = new JObject(); DualDate dd = (DualDate)value; result.Add("DateOne", JToken.FromObject(dd.DateOne.ToString("MM.dd.yyyy"))); result.Add("DateTwo", JToken.FromObject(dd.DateTwo)); result.WriteTo(writer); } // Other JsonConverterMethods public override bool CanConvert(Type objectType) { return objectType == typeof(DualDate); } public override bool CanWrite { get { return true; } } public override bool CanRead { get { return false; } } public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { throw new NotImplementedException(); }}
