C# json与对象之间的相互转换

1. 添加命名空间

using System.Runtime.Serialization.Json;

2. WriteObject方法

 // 从一个对象信息生成Json串
        public static string ObjectToJson(object obj)
        {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            MemoryStream stream = new MemoryStream();
            serializer.WriteObject(stream, obj);
            byte[] dataBytes = new byte[stream.Length];
            stream.Position = 0;
            stream.Read(dataBytes, 0, (int)stream.Length);
            return Encoding.UTF8.GetString(dataBytes);
        }

3. ReadObject方法

  // 从一个Json串生成对象信息
        public static object JsonToObject(string jsonString, object obj)
        {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            MemoryStream mStream = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
            return serializer.ReadObject(mStream);
        }
