Json序列化與反序列化方法解析_jquery

複製程式碼 程式碼如下:

 ///

 ///

  Json序列化,用於傳送至客戶端        ///

        public static string ToJsJson(this 

            DataContractJsonSerializer serializer = new DataContractJsonSerializer(item.GetType());

            using (MemoryStream ms = new MemoryStream())

            {

                serializer.WriteObject(ms, item);

                StringBuilder sb = new StringBuilder();

                sb.Append(Encoding.UTF8.GetString(ms.ToArray()));

                return sb.ToString();

            }

        }

        ///

        /// Json反序列化,用於接收客戶端Json後產生對應的物件
  sonTo(this string jsonString)
        {

            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));

            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));

            T jsonObject = (T)ser.ReadObject(ms);

            ms.Close();

            return jsonObject;

        }

------------------javascript取得Json-------------------- javascript呼叫測試程式碼

複製程式碼 程式碼如下:

$('#getJson').click(function() {
                dler.ashx",
                    模式： 'GET ',
                    資料：{}，
                       逾時：1000，
                                  成功：函數（結果) {

                       警報(結果.make);
                                                 }

                });
            代碼


代碼如下：

public class getJsonHandler: IHttpHandler
    {

public void ProcessRequest(Http   Obj obj = new TestObj();

            obj.make = "製造為價值";

            obj. 🎜>            obj.color = "顏色為值";             context.Response.Write(obj.ToJsJson());               get            {            >        }}

//回傳值{"color":"Color is Value","make":"Make is Value","model":"Model is Value","year":999}

                var m_obj = { make: "Dodge", model: "Coronet R/T", Year: 1968, color: "yellow h Str = JSON.stringify(m_obj); //用Json2 .js產生Json字串

                $.ajax({
