js前端構造json對象后台接收並反序列化

這是前台構造json對象的代碼

[DataContract]//構造一個對象模型
    class Person
    {
        [DataMember]
        public string unionContentId { get; set; }
        [DataMember]
        public string contentCompanyId { get; set; }
        [DataMember]
        public string tableId { get; set; }
        [DataMember]
        public string proIds { get; set; }
        [DataMember]
        public string time { get; set; }
        [DataMember]
        public string people { get; set; }
    }

/// <summary>
    /// JSON序列化和反序列化輔助類
    /// </summary>
    public class JsonHelper
    {
        /// <summary>
        /// JSON序列化
        /// </summary>
        public static string JsonSerializer<T>(T t)
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            MemoryStream ms = new MemoryStream();
            ser.WriteObject(ms, t);
            string jsonString = Encoding.UTF8.GetString(ms.ToArray());
            ms.Close();
            return jsonString;
        }

        /// <summary>
        /// JSON反序列化
        /// </summary>
        public static T JsonDeserialize<T>(string jsonString)
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
            T obj = (T)ser.ReadObject(ms);
            return obj;
        }
    }
//調用方法
List<Person> outPerson = new List<Person>();
outPerson = JsonHelper.JsonDeserialize<List<Person>>(Request.QueryString["UnionContent"]);

這是后台處理代碼
