Question

int i = 0;
int x = 10;
List<int> group = new List<int>();

while (i < x)
{
    RichTextBoxShowTafel.AppendText(Convert.ToString(group[i]));
    i++;
}

Why does this not work? I want to display the first 10 numbers of the List called: “group”.

edit:
I actually want to create variables and print it in a row…

Answer 1

You never put anything in the group variable. You only instantiated an empty list.

And you’d be better off doing this:

foreach (int item in group)
{
  RichTextBoxShowTafel.AppendText(item.ToString());
}
