I need help setting up this code for an assignment

I am just trying to get this work done, I need help with the first few steps of the code.

Here is what I have so far...

namespace SavingsAccount
{
    public class SavingsAccount
    {
        private static double annualInterestRate;
        private double savingsBalance;

        System.String savingsAccountName
        {
            get => getSavingsAccountName;
            set => setSavingsAccountName = value;
        }
       
    }
}

namespace SavingsAccount
{
    public class SavingsAccount
    {
        private static double annualInterestRate;
        private double savingsBalance;

        System.String savingsAccountName
        {
            get => getSavingsAccountName;
            set => setSavingsAccountName = value;
        }
       
    }
}

For now, I am focusing on completing: -Create SavingsAccount class with static variable annualInterestRate and private instance variables savingsBalance (double) and savingsAccountName (string). -Create a mutator method to set the savingsAccountName. Call this method setSavingsAccountName. The method should take a string argument and return void. -Create an accessor method to retrieve the savingsAccountName. Call this method getSavingsAccountName. The method should take no arguments and return a string (i.e. the savingsAccountName). How am I doing so far? It's bad I know but this is me attempting it without much knowledge of C#

You have no mutator methods here Your code will not compile Whoever gave you the assignment is mentally stuck with 1999 Java, but it really doesn't seem like they want you to use properties Rather, they want you to create getter and setter methods Also, no need for System.String, just the string alias works

A mutator method is just setter right?

Angius•9mo ago

It's a method that mutates the state of the class Normally, in sane circumstances, you would use a property with a setter indeed But the assignment clearly states you need a method

AppleCyder (NovaSprite)OP•9mo ago

What would a mutator method look like then?

Angius•9mo ago

A method That changes the value of the field There's nothing special about it Just a regular ol' method

AppleCyder (NovaSprite)OP•9mo ago

Ohh so it's those lines that have public static void at the top right?? and using

 get => getSavingsAccountName;
 set => setSavingsAccountName = value;

 get => getSavingsAccountName;
 set => setSavingsAccountName = value;

is never going to work is it? Is this better?

 public double SavingsBalance
 {
     get => Return SavingsBalance;
     set => SavingsBalance = value;
 }

 public double SavingsBalance
 {
     get => Return SavingsBalance;
     set => SavingsBalance = value;
 }

think about what happens when you try to get the value of SavingsBalance here you're telling it to look at SavingsBalance, which needs to look at SavingsBalance, which needs to look at SavingsBalance... you need a backing field that actually stores the value to avoid infinite recursion you can either do that explicitly or if you don't have any special logic just use an auto-property like

public double SavingsBalance { get; set; }

public double SavingsBalance { get; set; }

So like this...?

 public double SavingsBalance
{
    get => Return SavingsBalance;
    set => SavingsBalance = value * CalculateMonthlyInterest (value);
}

 public double SavingsBalance
{
    get => Return SavingsBalance;
    set => SavingsBalance = value * CalculateMonthlyInterest (value);
}

That is still a property
