Serialization- list in a jason format

Question

I tring to write the code to this exercise, but i have no idea how to do it. Please help me. Tips are very welcomed. So in the console C # application, create a Man class that has 2 properties, a string type and an int type. From the console, read the name and age pair at the input. Create a new instance of Man for each pair and add it to the List list. The input ends with the user typing the file name instead of the human name and entering -1 as the age. Serialize the inserted List in json format into the specified file. PS Thanks for solving it TT

Hi, Install Newton.Json from Nuget Package: and Use this Code In ManInfo You will get your Json Result using System; using System.Collections.Generic; using System.IO; using System.Text; using Newtonsoft.Json; namespace ConsoleApp4 { class Man { public string name { get ; set ; } public string age { get ; set ; } } class Program { static void Main() { var list = new List string >(); List Manlist = new List (); // dynamic Manlist; var fileStream = new FileStream(@ "d:\file.txt" , FileMode.Open, FileAccess.Read); using (var streamReader = new StreamReader(fileStream, Encoding.UTF8)) { string line; while ((line = streamReader.ReadLine()) != null ) { list.Add(line); } } foreach (var s in list) { var manp = s.Split( '|' ); Man obj = new Man(); obj.name = Convert.ToString(manp[0]); obj.age = Convert.ToString(manp[1].Trim()); Manlist.Add(obj); } var ManInfo = string .Empty; ManInfo = JsonConvert.SerializeObject(Manlist); } } }

Hi, Convert your List to Json Format by SerializeObject Like: Eg: var ProjectInfo = string .Empty; ProjectInfo = JsonConvert.SerializeObject(YourList);
