How to check if two values are in the same child of a class?

The user inputs their username and then their password. I want to check to see if both inputs are in the same child of the class.

You might need to show some code because it's not very clear what you are asking.

my bad,

while(!fileReader.EndOfStream){
                string lineOfData = fileReader.ReadLine()!;
                string[] accountData = lineOfData.Split(",");
                string accountNumber = accountData[0];
                int accountPIN = int.Parse(accountData[1]);
                string first_name = accountData[2];
                string last_name = accountData[3];
                float accountBalance = float.Parse(accountData[4]);
                int totalDeposits = int.Parse(accountData[5]);
                int totalWithdrawals = int.Parse(accountData[6]);
                string accountType = (accountData[7]); 
                accountList.Add(new Account(accountNumber,accountPIN, first_name, last_name, accountBalance, totalDeposits, totalWithdrawals, accountType));

while(!fileReader.EndOfStream){
                string lineOfData = fileReader.ReadLine()!;
                string[] accountData = lineOfData.Split(",");
                string accountNumber = accountData[0];
                int accountPIN = int.Parse(accountData[1]);
                string first_name = accountData[2];
                string last_name = accountData[3];
                float accountBalance = float.Parse(accountData[4]);
                int totalDeposits = int.Parse(accountData[5]);
                int totalWithdrawals = int.Parse(accountData[6]);
                string accountType = (accountData[7]); 
                accountList.Add(new Account(accountNumber,accountPIN, first_name, last_name, accountBalance, totalDeposits, totalWithdrawals, accountType));

is how im making my objects

class Account{
    private string first_name, last_name, accountType, accountNumber;
    private int accountPIN, totalDeposits, totalWithdrawals;

    private float accountBalance;


    public Account (string accountNumber, int accountPIN, string first_name, string last_name, float accountBalance, int totalDeposits, int totalWithdrawals, string accountType){

    }
    ///get and set ended
    ///methods begin now
    
}

is how my class is set up so basically what im trying to check is if the accountnumber that the user inputs contains a matching pin in one of the objects I have made

Angius•2y ago

Well, check that, then userInput.Contains(someAccount.Pin) (as a side note, most of your code is useless Java-isms, C# has autoproperties, no need to waste time writing getter and setter methods)

ohh ok nice ill fix that in a few so I'm in the process of doing that right now but whenever I try to access my objects I get the output of

Angius•2y ago

How are you accessing them and how are you getting the output?

0_00OP•2y ago

foreach(Account account in accountList){
                Console.WriteLine(account);
            }

foreach(Account account in accountList){
                Console.WriteLine(account);
            }

Angius•2y ago

Well, your account doesn't override the ToString() method so you'll just get the class name If you want to print all properties of the object, you can try serializing it to JSON

foreach (var account in accounts)
{
    Console.WriteLine(JsonSerializer.Serialize(account));
}

foreach (var account in accounts)
{
    Console.WriteLine(JsonSerializer.Serialize(account));
}

or some such

okok that makes sense Im trying to make the login right now and when I do

if(currentaccountNumber.Contains(accountNumber) && currentPIN1.Contains(accountPIN));

if(currentaccountNumber.Contains(accountNumber) && currentPIN1.Contains(accountPIN));

it tells me that accountNumber and accountPIN dont exist in the current context currentaccountNumber and currentPIN1 are the user input

Angius•2y ago

Well, do they exist? $scopes

MODiX•2y ago

scope A {
  thing a;
  scope B {
    thing b;
  }
}

scope A {
  thing a;
  scope B {
    thing b;
  }
}

thing a is available in scope A and scope B thing b is available only in scope B
