问题如下：当对象实现时
IEnumerable，JSON.net将其标识为值数组，并按照数组Json语法（不包括属性）对其进行序列化，例如：
[ {"FooProperty" : 123}, {"FooProperty" : 456}, {"FooProperty" : 789}]如果要序列化它保留属性，则需要通过定义一个custom来手工处理该对象的序列化
JsonConverter：
// intermediate class that can be serialized by JSON.net// and contains the same data as FooCollectionclass FooCollectionSurrogate{ // the collection of foo elements public List<Foo> Collection { get; set; } // the properties of FooCollection to serialize public string Bar { get; set; }}public class FooCollectionConverter : JsonConverter{ public override bool CanConvert(Type objectType) { return objectType == typeof(FooCollection); } public override object ReadJson( JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { // N.B. null handling is missing var surrogate = serializer.Deserialize<FooCollectionSurrogate>(reader); var fooElements = surrogate.Collection; var fooColl = new FooCollection { Bar = surrogate.Bar }; foreach (var el in fooElements) fooColl.Add(el); return fooColl; } public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { // N.B. null handling is missing var fooColl = (FooCollection)value; // create the surrogate and serialize it instead // of the collection itself var surrogate = new FooCollectionSurrogate() { Collection = fooColl.ToList(), Bar = fooColl.Bar }; serializer.Serialize(writer, surrogate); }}然后按以下方式使用它：
var ss = JsonConvert.SerializeObject(collection, new FooCollectionConverter());var obj = JsonConvert.DeserializeObject<FooCollection>(ss, new FooCollectionConverter());
