ASP. net c # Use JavaScriptSerializer for serialization and deserialization to obtain JSON

In JavaScriptSerializer, we can see the following methods or constructor, they are all instance methods:

Member	Description

JavaScriptSerializer (JavaScriptTypeResolver)	The constructor is used to create a new JavaScriptSerializer object and map a specific type and identity string using the specified JavaScriptTypeResolver.
ConvertToType <T> (Object)	Converts a given object to type T.
Deserialize <T> (String)	Converts a JSON string to type T.
DeserializeObject (String)	Converts a JSON string into an object.
MaxJsonLength	Gets or sets the maximum length of the JSON string that can be accepted during serialization.
RecursionLimit	Obtain or set the maximum recursion depth when deserializing a json string.
RegisterConverters (IEnumerable <JavaScriptConverter>)	Register the JavaScriptConveter object used during serialization.
Serialize (Object)	Serialize an object into a JSON string.

public class UserInfo  {

      public Int32 Id { get; set; }

      public String UserName { get; set; }

      public DateTime Time { get; set; } 

      public bool Gender { get; set; }  }

Next, write the following code in Page_Load.

protected void Page_Load(object sender, EventArgs e)

  {

      UserInfo info = new UserInfo();

      info.Id = 1;

Info. UserName = "modembo http://maoblog.com ";

      info.Time = DateTime.Now;

      info.Gender = true;

        System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer();

      String strJson = jss.Serialize(info);

      Response.Write(strJson);

// Output result:

// {"Id": 1, "UserName": "maobo http://maoblog.com", "Time": "\/Date (1297950721668 \/", "Gender": true}

        UserInfo info2 = jss.Deserialize<UserInfo>(strJson);

      Response.Write(String.Format("<br/>{0}<br/>{1}<br/>{2}<br/>{3}", info2.Id, info2.UserName, info2.Time, info2.Gender));

      Response.End();

// Result: // 1 // modembo http://maoblog.com // 14:00:29 // True}
