ListItem li = new ListItem(TextBox1.Text);
if (!ListBox1.Items.Contains(li))
{
ListBox1.Items.Add(TextBox1.Text);
}
else
{
Response.Write("repeated");
}

Your error is index is out of range. It is because listbox has N items you are counting them from 0. So the last listitem index is N-1.But you are counting upto N.So it is giving as error.
Let me know it is useful to u or not.......

hi friend,
try this code
int i;
for (i = 0; i <= ListBox1.Items.Count-1; i++)
{
if (TextBox1.Text!=ListBox1.Items[i].Text)
{
ListBox1.Items.Add(TextBox1.Text);
}
else
{
Response.Write("repeated");
}
}

The "=" in "i <= ListBox1.Items.Count" is the culprit. Remove it
and rewrite as
i<ListBox1.Items.Count
