Keadaan semasa objek mesti diperolehi untuk menyimpannya atau untuk mendapatkannya kemudian dan ini harus dipertimbangkan semasa pengekodan, kod tersuai ditambah untuk mengeluarkan keadaan objek dan ini dipanggil menukar objek kepada rentetan Json dalam C# dan pengekodan mesti dilakukan untuk setiap dan setiap sifat objek bergantung pada jenis pengetahuan yang kita ada pada jenis objek. Kod mesti ditukar apabila dan apabila terdapat perubahan dalam definisi jenis objek dan kami menggunakan perpustakaan Json.NET Newtonsoft untuk menukar objek kepada Json dalam C# yang memberikan kami perwakilan lengkap rentetan objek kami menggunakan kod ditulis dalam satu baris.
Sintaks:
Variable variable_name =Newtonsoft.Json.JsonConvert.SerializeObject(parameter);
Diberikan di bawah adalah contoh yang dinyatakan:
Atur cara C# untuk menunjukkan penukaran objek kepada rentetan Json yang tidak lain hanyalah penyirian objek dalam C#.
Kod:
using Newtonsoft.Json; using System; using System.Collections.Generic; using System.IO; //a namespace called Serial is defined namespace Serial { //a class called Data is defined public class Data { //a string variable is defined which can be set or retrieved using get or set method public string Name1 { get; set; } //a list is defined which can be set or retrieved using get or set method public List<int> Ids { get; set; } //a method called Print is defined in which the name and the list is printed public void Print() { Console.WriteLine("The Name is: " + Name1); Console.WriteLine("The Identifiers used are: " + string.Join<int>(",", Ids)); Console.WriteLine(); Console.WriteLine(); } } //a class called check is defined public class Check { //a file path is defined and stored in a string variable const string fPath = @"d:\ex.txt"; //Serialize method is defined in which instances of Json writer and Stream writer classes are defined to write into the file public static void Serialize(object ob) { varserialise = new JsonSerializer(); using (var ns = new StreamWriter(fPath)) using (JsonWriter writer1 = new JsonTextWriter(ns)) { serialise.Serialize(writer1, ob); } } //Deserialize method is defined in which instances of Json text reader and Stream reader classes are defined to read from the file public static object Deserialize(string pa) { varserialise = new JsonSerializer(); using (var ns = new StreamReader(pa)) using (var reader1 = new JsonTextReader(ns)) { return serialise.Deserialize(reader1); } } //main method is called public static void Main(string[] args) { vardat = new Data { Name1 = "ShobhaShivakumar", Ids = new List<int>{ 10, 20, 30, 40 } }; Console.WriteLine("Before serialization of the objects, the list of the objects are:"); Console.WriteLine("-------------------------------------------------------------------"); Console.WriteLine(); dat.Print(); Serialize(dat); vardeserialise = Deserialize(fPath); Console.WriteLine("After de-serialization of the object, the objects are:"); Console.WriteLine("---------------------------"); Console.WriteLine(); Console.WriteLine(deserialise); } } }

Kod:
using System; using System.Text; using System.Collections.Generic; //a class called check is defined public class Check { //main method is called public static void Main() { //an instance of the Create request1 class and string builder class is created var request = CreateRequest1(); var output1 = new StringBuilder(); //Since we are using manual serialization here, we have to output the properties manually output1.AppendFormat("The unique ID is: {0}\n", request.UniqueID); output1.AppendFormat("The unique Name is: {0}\n", request.UniqueName); output1.AppendFormat("The unique Surname is: {0}\n", request.UniqueSurname); output1.AppendFormat("The Last Sign In is: {0}\n", request.UniqueLastSignIn); //We need to make use of for loop to output the nested attributes in case of manual serialization output1.AppendFormat("The Attributes are:\n"); foreach (varsh in request.UniqueAttributes) { output1.AppendFormat(" {0}\n", sh); } Console.WriteLine(output1.ToString()); Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(request); //We are using Json serialization to improve the readability Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(request, Newtonsoft.Json.Formatting.Indented)); } //a method called Create request1 is defined public static Req CreateRequest1() { return new Req { UniqueID = 10, UniqueName = "Shobha", UniqueSurname = "Shivakumar", UniqueLastSignIn = DateTime.Now, UniqueAttributes = new List<string> { "Beautiful", "Tall", "Intelligent", "Wise", } }; } //a class called req is created public class Req { public intUniqueID {get;set;} public string UniqueName {get;set;} public string UniqueSurname {get;set;} public DateTimeUniqueLastSignIn {get;set;} public List<string>UniqueAttributes {get;set;} } }
