[C#] Remove duplicates from listbox

This is a little snippet I wrote for a project im working on

Anyways here you go.

  public void RemoveListboxDuplicates(ListBox ListBox)

  {

    List<String> Removed = new List<String>();

    for (int I = 0; I < ListBox.Items.Count;I++)

    {

    if (!Removed.Contains(ListBox.Items[i].ToString()))

    {

    Removed.Add(ListBox.Items[i].ToString());

    }

    }

    ListBox.Items.Clear();

    foreach (String S in Removed)

    {

    ListBox.Items.Add(S);

    }
