Show only matched items in ListBox (C#)?

I write quick search function for searching matched items in ListBox:

 for (int i = listBox1.Items.Count - 1; i >= 0; i--)
            {
                if (listBox1.Items[i].ToString().Contains(textBox1.Text))
                {
                    listBox1.SetSelected(i, true);
                }
            }

It selects first matched item. How can I temporarily hide all other items not matching the search query (inside this ListBox1)?

By the way, ListBox contains only numbers, no text stings.

Assuming the SelectionMode property is set for MultiExtended, try moving your "if" condition into the boolean parameter:

for (int i = listBox1.Items.Count - 1; i >= 0; i--) {
  listBox1.SetSelected(i, listBox1.Items[i].ToString().Contains(textBox1.Text));
}
