What is the best way to save/load information on startup and closing program?

there is no one best way, but if you just want a suggestion to start with you can use System.Text.Json to convert a C# object to and from text and store it in a file there are different formats, databases, etc that may be more or less appropriate depending on the details of what you're trying to do

I basically have to store 4 strings as 1 object and I have to edit and save the file on a button click event

my suggestion is probably your best option then, assuming your course doesn't have any restrictions on how to do it or what libraries you can use

I will try it I will create a backup of my project first I checked microsoft learn and they dont have anything there on json am I supposed to be using Newtonsoft.Json?

in general, go with System.Text.Json nowadays

monkeyoohlalaOP•4w ago

is newtonsoft the same as regular json? are there any free tutorials you can recommend? I know what json does but have not really used it before when I was doing java

Sehra•4w ago

newtonsoft.json is just a library to work with json, it was the common one before system.text.json was added to .net

ay ay captain are there any dangers in using json?

var jsonString = JsonSerializer.Serialize(newAccount);
var fileName = "Data.json";
File.AppendAllText(fileName, jsonString);

var jsonString = JsonSerializer.Serialize(newAccount);
var fileName = "Data.json";
File.AppendAllText(fileName, jsonString);

 var fileName = "Data.json";
 if (File.Exists(fileName))
 {
     string json = File.ReadAllText(fileName);
     List<Account> accounts = JsonSerializer.Deserialize<List<Account>>(json);
     foreach (var account in accounts)
     {
         ListAccounts.Add(account);
     }
 }

 var fileName = "Data.json";
 if (File.Exists(fileName))
 {
     string json = File.ReadAllText(fileName);
     List<Account> accounts = JsonSerializer.Deserialize<List<Account>>(json);
     foreach (var account in accounts)
     {
         ListAccounts.Add(account);
     }
 }
