.Net 2.0自带的Json序列化、反序列化方法

public class JsonUtil
{
public static T DeserializeObject<T>(string json)
{
DataContractJsonSerializer jsonFormator = new DataContractJsonSerializer(typeof(T));
using (Stream readStream = new MemoryStream(Encoding.UTF8.GetBytes(json)))
{
return (T)jsonFormator.ReadObject(readStream);
}
}

public static string SerializeObject(object obj)
{
DataContractJsonSerializer jsonFormator = new DataContractJsonSerializer(obj.GetType());
using (MemoryStream stream = new MemoryStream())
{
jsonFormator.WriteObject(stream, obj);
return Encoding.UTF8.GetString(stream.ToArray());
}
}
}
