JSON .Net Unity反序列化匿名对象字典 [英] JSON .Net Unity Deserialize dictionary of anonymous objects
问题描述
我有一个字典,我将其序列化为一个二进制文件,然后使用JSON .net从 https://进行反序列化. json.codeplex.com/
I have a Dictionary that I serialize onto a binary file, and deserialize back again using JSON .net from https://json.codeplex.com/
字典可能包含缩写对象(字符串,类,甚至是List).每个类都是[System.Serializable]
The dictionary may contain abritrary objects (string, classes, even List). Each class is [System.Serializable]
在序列化时,我添加了serializer.TypeNameHandling = TypeNameHandling.All;确保反序列化器具有反序列化字典所需的类型信息.
At serialize time, I add serializer.TypeNameHandling = TypeNameHandling.All; to make sure the deserializer has the type info required to deserialize the dictionary.
我无法正确地将其反序列化为相同的对象列表,我仅在我的容器中获得JObjects,而不是原始类型.谁能帮我完成这个任务?
I am unable to deserialize it correctly to the identical list of object, I only get JObjects in my container and not the original type. Can anyone help me accomplish this?

更新:
要获取数据,我使用这两种方法:
To get data in / out I use those two methods:
public static byte[] SerializeToByteArray<T>(T data)
{
byte[] serializedData = new byte[]{};
using(var stream = new MemoryStream())
{
using (BsonWriter writer = new BsonWriter(stream))
{
JsonSerializer serializer = new JsonSerializer();
serializer.TypeNameHandling = TypeNameHandling.All;
serializer.Serialize(writer, data);
}
return stream.ToArray();
}
}
public static T DeserializeFromByteArray<T>(byte[] serializedData )
{
using (var stream = new MemoryStream(serializedData))
{
using (BsonReader reader = new BsonReader(stream))
{
JsonSerializer serializer = new JsonSerializer();
return (T)serializer.Deserialize<T>( reader );
}
}
}
[System.Serializable]
public class FavoriteLevel
{
public FavoriteLevel(string ID, int TYPE) { id = ID; type = TYPE;}
public string id;
public int type;
}
Dictionary<string,object> dict = new Dictionary<string,object>(1);
List<FavoriteLevel> levels = new List<FavoriteLevel>(1);
levels.Add (new FavoriteLevel("123",FavoriteType.Favorite) );
dict.Add ( "123", levels );
byte[] data = SerializeToByteArray( dict );
Dictionary<string,object> incomingDict = DeserializeFromByteArray<Dictionary<string,object>>( data );
object listBack = incomingDict["123"];
// ERROR: listBack is a Json object and not a List<FavoriteLevel> object
推荐答案
反序列化和序列化时需要设置serializer.TypeNameHandling = TypeNameHandling.All
.否则,"$type"
属性将被忽略.
You need to set serializer.TypeNameHandling = TypeNameHandling.All
when deserializing as well as serializing. Otherwise, the "$type"
property will be ignored.
因此:
public static class JsonExtensions
{
public static byte[] SerializeToByteArray<T>(T data, JsonSerializerSettings settings)
{
using (var stream = new MemoryStream())
{
using (var writer = new BsonWriter(stream))
{
JsonSerializer serializer = JsonSerializer.Create(settings);
serializer.Serialize(writer, data);
}
return stream.ToArray();
}
}
public static T DeserializeFromByteArray<T>(byte[] serializedData, JsonSerializerSettings settings)
{
using (var stream = new MemoryStream(serializedData))
{
using (var reader = new BsonReader(stream))
{
JsonSerializer serializer = JsonSerializer.Create(settings);
return (T)serializer.Deserialize<T>(reader);
}
}
}
}
public static class TestClass
{
public static void Test()
{
Dictionary<string, object> dict = new Dictionary<string, object>(1);
List<FavoriteLevel> levels = new List<FavoriteLevel>(1);
levels.Add(new FavoriteLevel("123", 0));
dict.Add("123", levels);
var settings = new JsonSerializerSettings();
settings.TypeNameHandling = TypeNameHandling.All;
byte[] data = JsonExtensions.SerializeToByteArray(dict, settings);
Dictionary<string, object> incomingDict = JsonExtensions.DeserializeFromByteArray<Dictionary<string, object>>(data, settings);
object listBack = incomingDict["123"];
Debug.Assert(listBack.GetType() == levels.GetType()); // No assert.
}
}
