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); }
