You are not splitting the TextBox1.Text correctly: you're not reading each line as a separate string. You are reading the entire string and then splitting it.

You can accomplish what you are asking much more simply. This is a simple version of what I believe you're trying to do, and it could even be simplified further if desired.

private void button1_Click(object sender, EventArgs e)
{
    string[] oldString = TextBox1.Text.Split(
        new string[]{","},
        StringSplitOptions.RemoveEmptyEntries);
    ListBox1.Items.AddRange(oldString);
}

This is a button click event that splits the text from TextBox1 by , characters, then adds each item to ListBox1 using the Items.AddRange(string[] items) method.

If we wanted to manually update the listbox one item at a time instead, we can use a foreach loop instead.

private void button1_Click(object sender, EventArgs e)
{
    string[] oldString = TextBox1.Text.Split(
        new string[]{","},
        StringSplitOptions.RemoveEmptyEntries);
    foreach (string item in oldString)
    {
        ListBox1.Items.Add(item);
    }
}
