Does .NET 4 have a built-in JSON serializer/deserializer?
提问by Cheung
Does .NET 4 come with any class that serializes/deserializes JSON data?
.NET 4 是否带有任何序列化/反序列化 JSON 数据的类？
I know there are 3rd-party libraries, such as JSON.NET, but I am looking for something built right into .NET.
I found Data Contractson MSDN, but it is for WCF, not for Winforms or WPF.
我知道有 3rd 方库，例如JSON.NET，但我正在寻找内置于 .NET 的东西。
我在 MSDN 上找到了Data Contracts，但它适用于 WCF，而不适用于 Winforms 或 WPF。

You can use the DataContractJsonSerializerclass anywhere you want, it is just a .net class and is not limited to WCF. More info on how to use it hereand here.
您可以在任何地方使用DataContractJsonSerializer类，它只是一个 .net 类，不限于 WCF。有关如何在此处和此处使用它的更多信息。

There's the JavaScriptSerializerclass (although you will need to reference the System.Web.Extensionsassembly the class works perfectly fine in WinForms/WPF applications). Also even if the DataContractJsonSerializerclass was designed for WCF it works fine in client applications.
有JavaScriptSerializer类（尽管您需要引用 System.Web.Extensions程序集，该类在 WinForms/WPF 应用程序中工作得非常好）。此外，即使DataContractJsonSerializer类是为 WCF 设计的，它在客户端应用程序中也能正常工作。

Use this generic class in order to serialize / deserialize JSON. You can easy serialize complex data structure like this:
使用这个通用类来序列化/反序列化 JSON。您可以像这样轻松序列化复杂的数据结构：
Dictionary<string, Tuple<int, int[], bool, string>>
to JSON string and then to save it in application setting or else
到 JSON 字符串，然后将其保存在应用程序设置中或其他
public class JsonSerializer
{
public string Serialize<T>(T aObject) where T : new()
{
T serializedObj = new T();
MemoryStream ms = new MemoryStream();
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
ser.WriteObject(ms, aObject);
byte[] json = ms.ToArray();
ms.Close();
return Encoding.UTF8.GetString(json, 0, json.Length);
}
public T Deserialize<T>(string aJSON) where T : new()
{
T deserializedObj = new T();
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(aJSON));
DataContractJsonSerializer ser = new DataContractJsonSerializer(aJSON.GetType());
deserializedObj = (T)ser.ReadObject(ms);
ms.Close();
return deserializedObj;
}
}

.NET4 has a built-in JSON Class,such as DataContractJsonSerializer ,but it is very weak,it doesn't support multidimentional array. I suggest you use JSON.Net
.NET4 有一个内置的 JSON 类，例如 DataContractJsonSerializer ，但它非常弱，它不支持多维数组。我建议你使用 JSON.Net
