Serialize/Deserialize a byte array in JSON.NET
提问by Steve Randall
I have a simple class with the following property:
我有一个具有以下属性的简单类：
[JsonObject(MemberSerialization.OptIn)]
public class Person
{
...
[JsonProperty(PropertyName = "Photograph"]
public byte[] Photograph { get; set; }
...
}
but this doesn't work when I populate the Photograph property with an image and transfer over http. This may sound like a simple question but I've yet to find a solution after looking online for hours, but, how do I serialise/deserialise a byte array in Json.NET? What attribute tags do I need, or, should I be doing this another way? Many thanks!
但是当我用图像填充照片属性并通过 http 传输时，这不起作用。这听起来像是一个简单的问题，但我在网上看了几个小时后还没有找到解决方案，但是，如何在 Json.NET 中序列化/反序列化字节数组？我需要什么属性标签，或者，我应该以另一种方式这样做吗？非常感谢！

You can convert the byte[] into a string then use the JsonConvert method to get the object:
您可以将 byte[] 转换为字符串，然后使用 JsonConvert 方法获取对象：
var bytesAsString = Encoding.UTF8.GetString(bytes);
var person = JsonConvert.DeserializeObject<Person>(bytesAsString);

public static T Deserialize<T>(byte[] data) where T : class
{
using (var stream = new MemoryStream(data))
using (var reader = new StreamReader(stream, Encoding.UTF8))
return JsonSerializer.Create().Deserialize(reader, typeof(T)) as T;
}

If you are using LINQ to JSON, you can do this:
如果您使用LINQ to JSON，您可以这样做：
JObject.Parse(Encoding.UTF8.GetString(data));
The result will be a dynamic JObject.
结果将是动态的JObject。
While this might not be exactly what the OP was looking to do, it might come in handy for others looking to deserialize a byte[]that come across this question.
虽然这可能不是 OP 真正想要做的，但对于希望反序列化byte[]遇到这个问题的其他人来说，它可能会派上用场。
