Question

I have this:

string curr = "";
if (emails.SelectedItem != null)
{
  for (int i = 0; i <= 19; i++)
  {
    curr = (emails.SelectedItem.ToString()[i] + "." + 
            emails.SelectedItem.ToString()[i + 1]);
    clone.Items.Add(curr);
  }
}

However, whenever I run it, it gives me the “index was out of bounds of the array” error.

Why? What’s the fix?

Also, how do I make it add the rest of the string (not just i + 1) to clone?

EXPLANATION OF CODE:

I’m trying to insert a period (.) after one letter of the word, then add it to clone. After that, I want to add a period after the SECOND letter, add to clone, period after third letter, add, etc…

However, I don’t want to have it be t.h.i.s.i.s.t.h.e.n.a.m.e, I want it to just have one period at a time.

It should look like:

a.ntimatter
an.timatter
ant.imatter
anti.matter
etc…

if (emails.SelectedItem != null)
{
    var item = emails.SelectedItem.ToString();
    for (int i = 1; i < item.Length; i++)
    {
         clone.Items.Add(item.Insert(i, "."));
    }
}
