I'm trying to search through a sorted list to find an item that is entered into a textbox. However, when I try to add an else statement to the Find() method such as:
void Find(object sender, EventArgs e)
{
    foreach(DictionaryEntry Item in mySortedList)
    {
        if(findBox.Text == Item.Key.ToString())
        {
            findLbl.Text = "You have found " + "<b>" + Item.Key.ToString() + ".</b><br/>";
            findLbl.Text +="<b> Definition: </b>" + Item.Value.ToString();
        }
               else
                {
                  findLbl.Text = "That item is not in the List";
                }
    }
}

It doesn't find anything except for the last item in the list, which in this case is Zebra, but it works fine when the else statement is not in there. Can anyone explain to me why this is?
