Question

I have an array:

class Words
{
   public static string[] wordsArray = { "one", "two", "three", "four" };
}

TextBlock which displays an array of values, and button that displays the next value of the array:

private int counter = 0;

    private void goButton_Click(object sender, RoutedEventArgs e)
    {

        if (counter < Words.wordsArray.Length)
        {
            enWordTextBlock.Text = Words.wordsArray[counter++];
        }
    }

When the box appears on the last value of the array, the program will continue to not work, how to make it work in a “circle”?

Thanks all!

Answer 1

This should work:

private void goButton_Click(object sender, RoutedEventArgs e)
{
    counter++; //increase the counter
    int i = counter % Words.wordsArray.Length; //modulo operation
    enWordTextBlock.Text = Words.wordsArray[i]; //set text
}
