下面的对象与json串之间的转换在framework2.0下测试通过 注意:需要下载 Newtonsoft.Json.dll,并引用到项目中 using System; using System.IO; using System.Text; using Newtonsoft.Json; namespace OfflineAcceptControl.UCTools { public class JsonTools { // 从一个对象信息生成Json串 public static string ObjectToJson(object obj) { return JavaScriptConvert.SerializeObject(obj); } // 从一个Json串生成对象信息 public static object JsonToObject(string jsonString, object obj) { return JavaScriptConvert.DeserializeObject(jsonString, obj.GetType()); } } } 下面的对象与json串之间的转换在framework3.5下测试通过 注意引用:System.Runtime.Serialization,System.ServiceModel.Web using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Runtime.Serialization; using System.Runtime.Serialization.Json; namespace CrjIIOfflineAccept.CrjIITools { public class JsonTools { // 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); } // 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); } } }
