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

 1     //JSON序列化和反序列化辅助类

 2     public class JsonHelper

 3     {

 4         // JSON序列化

 5         public static string JsonSerializer<T>(T t)

 6         {

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

 8             MemoryStream ms = new MemoryStream();

 9             ser.WriteObject(ms, t);

10             string jsonString = Encoding.UTF8.GetString(ms.ToArray());

11             ms.Close();

12             return jsonString;

13         }

14 

15         //JSON反序列化

16         public static T JsonDeserialize<T>(string jsonString)

17         {

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

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

20             T obj = (T)ser.ReadObject(ms);

21             return obj;

22         }

23 

24     }

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

 1   public class Person

 2         {

 3             public string Name { get; set; }

 4 

 5             public int Age { get; set; }

 6         }

 7 

 8         [WebMethod]

 9         public string HaiHai()

10         {

11             Person person = new Person();

12             person.Name = "jack";

13             person.Age =26;

14             string jsonstring = JsonHelper.JsonSerializer<Person>(person);

15         

16             return jsonstring;

17            

18         }

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

1  using (WebService1SoapClient client = new WebService1SoapClient())

2             {

3                 string ss = client.HaiHai();

4                 Response.Write(ss);

5                // context.Response.Write(ss);

6             }
