C#序列化JSON

首先先添加.NET引用

System.Runtime.Serialization.dll

System.ServiceModel.Web.dll

然后CS文件添加USing 引用

using System.ServiceModel.Web;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;

把JSON序列化成对象

 /// <summary>
        /// 反序列化JSON
        /// </summary>
        /// <typeparam name="T">返回类型</typeparam>
        /// <param name="jsonString">JSON字符串</param>
        /// <returns></returns>
        public static T JsonDeserialize<T>(string strJson)
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(strJson));
            T objT = (T)ser.ReadObject(ms);
            ms.Close();
            return objT;
        }

把对象序列化成JSON

 /// <summary>
        /// 序列化JSON
        /// </summary>
        /// <typeparam name="T">序列化对象类型</typeparam>
        /// <param name="objT">序列化对象</param>
        /// <returns></returns>
        public static string JsonSerializer<T>(T objT)
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            MemoryStream ms = new MemoryStream();
            ser.WriteObject(ms, objT);
            string jsonString = Encoding.UTF8.GetString(ms.ToArray());
            ms.Close();
            return jsonString;
        }
