Fill an array with numbers given by the user adding a number each time he presses the button-CodePudding

I have a basic form with a button and a textbox to insert a number

I want to keep the number inserted in the first index of the array, then if I put another number and I click the button, I want that number to be stored in the second index of the array and so on

I have to make a loop to increment the index but if I use the loop, the first number I put in the box, it's going to be stored in all the indexes of the array

Here's my code (doesn't work)

public partial class EXERCISES_ARRAYS : Form
{
    int[] numbers = new int[5];

    private void btnAdd_Click(object sender, EventArgs e)
    {
        int i = 0;

        int insertedNumber = Convert.ToInt32(txtInsertedValue.Text);

        for (int j = 0; j < 5; j  )
        {
            numbers[i] = insertedNumber;
            i  ;

            if (i == 5)
            {
                btnAdd.Enabled = false;
            }
        }
    }
}

You want a List, rather than an array. That will take care of all of this for you:

public partial class EXERCISES_ARRAYS : Form
{
    List<int> numbers = new List<int>();

    private void btnAdd_Click(object sender, EventArgs e)
    {
        numbers.Add(int.Parse(txtInsertedValue.Text));
    }
}

I don't think you need to add a for loop for this. Try this

int[] numbers = new int[5];
int i = 0;

private void BtnAdd_Click(object sender, RoutedEventArgs e)
{
      int insertedNumber = Convert.ToInt32(txtInsertedValue.Text);
      numbers[i] = insertedNumber;
      i  ;
      if (i == 5)
            {
                btnAdd.Enabled = false;
            }
}
