C# JSON字串序列化與還原序列化

標籤：json

第一種：使用JavaScriptSerializer類，適用Web平台

C#將對象序列化成JSON字串

using System.Web.Script;using System.Web.Script.Serialization;

            JavaScriptSerializer serializer = new JavaScriptSerializer();            foreach (DataRow dr in dt.Rows)            {                Dictionary<string, string> data = new Dictionary<string, string>();                data.Add("Dev_NO", dr["Dev_NO"].ToString());                data.Add("Dev_Name", dr["Dev_Name"].ToString());                data.Add("Ol_Phone", dr["Ol_Phone"].ToString());                data.Add("Ol_IP", dr["Ol_IP"].ToString());                data.Add("Ol_Status", dr["Ol_Status"].ToString());                list.Add(data);            }            Response.Write(serializer.Serialize(list));

輸出結果為：

[{"Dev_NO":"00066666","Dev_Name":"test","Ol_Phone":"13766668888","Ol_IP":"10.196.209.174","Ol_Status":"2"},{"Dev_NO":"000F0000","Dev_Name":"test_hzlkhq","Ol_Phone":"13066668888","Ol_IP":"192.168.1.198","Ol_Status":"2"}]

如何將Json字串轉換成對象使用呢？

public class Model    {        public string Dev_NO { get; set; }        public string Dev_Name { get; set; }        public string Ol_Phone { get; set; }        public string Ol_IP { get; set; }        public int Ol_Status { get; set; }    }

string requestMes="[{\"Dev_NO\":\"00066666\",\"Dev_Name\":\"test\",\"Ol_Phone\":\"13766668888\",\"Ol_IP\":\"10.196.209.174\",\"Ol_Status\":\"2\"},{\"Dev_NO\":\"000F0000\",\"Dev_Name\":\"test_hzlkhq\",\"Ol_Phone\":\"13066668888\",\"Ol_IP\":\"192.168.1.198\",\"Ol_Status\":\"2\"}]";JavaScriptSerializer serializer = new JavaScriptSerializer();var Json = serializer.Deserialize<List<Model>>(requestMes);

第二種使用DataContractJsonSerializer，適用通用平台

需要添加引用：System.ServiceModel.Web 和 System.Runtime.Serialization，然後使用Using：

using System.Runtime.Serialization.Json;using System.Runtime.Serialization;

public class Model    {        public string Dev_NO { get; set; }        public string Dev_Name { get; set; }        public string Ol_Phone { get; set; }        public string Ol_IP { get; set; }        public int Ol_Status { get; set; }    }

    public class Test    {        public static DataTable getData()        {            var a = "{\"Dev_NO\":\"00066666\",\"Dev_Name\":\"test\",\"Ol_Phone\":\"13766668888\",\"Ol_IP\":\"10.196.209.174\",\"Ol_Status\":\"2\"}";            var serializer = new DataContractJsonSerializer(typeof(List<DTUModel>));            var mStream = new MemoryStream(Encoding.UTF8.GetBytes(a.ToString()));            List<DTUModel> list = (List<DTUModel>)serializer.ReadObject(mStream);            DataTable dt = new DataTable();            return dt;        }    }
