JSON序列化与反序列化

DataContractJsonSerializer在System.Runtime.Serialization.Json命名空间下，.NET Framework 3.5包含在System.ServiceModel.Web.dll中，需要添加对其的引用；.NET Framework 4在System.Runtime.Serialization中。

1.创建 JsonHelper类

    //JSON序列化和反序列化辅助类
    public class JsonHelper
    {
        // JSON序列化
        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;
        }

        //JSON反序列化
        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;
        }

    }

2.创建web服务页面，进行序列化，并发布到本地服务器，我本地发布后的地址为：

http://localhost:8012/ceshi/WebService1.asmx?op=HaiHai

  public class Person
        {
            public string Name { get; set; }

            public int Age { get; set; }
        }

        [WebMethod]
        public string HaiHai()
        {
            Person person = new Person();
            person.Name = "jack";
            person.Age =26;
            string jsonstring = JsonHelper.JsonSerializer<Person>(person);
        
            return jsonstring;
           
        }

3.将接口发布到本地IIS，然后根据接口的地址，获取数据反序列化

 using (WebService1SoapClient client = new WebService1SoapClient())
            {
                string ss = client.HaiHai();
                Response.Write(ss);
               // context.Response.Write(ss);
            }
