Beispiel

Im folgenden Codebeispiel wird die Verwendung des Font-Konstruktors und der Eigenschaften Size, SizeInPoints und Unit veranschaulicht. Dieses Beispiel ist für die Verwendung mit einem Windows Form vorgesehen, das die ComboBoxComboBox1 mit den Zeichenfolgen "Bigger" und "Smaller" enthält. Fügen Sie den folgenden Code in das Formular ein, und ordnen Sie die ComboBox1_SelectedIndexChanged-Methode demSelectedIndexChanged-Ereignis des ComboBox-Steuerelements zu.

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

    ' Cast the sender object back to a ComboBox.
    Dim ComboBox1 As ComboBox = CType(sender, ComboBox)

    ' Retrieve the selected item.
    Dim selectedString As String = CType(ComboBox1.SelectedItem, String)

    ' Convert it to lowercase.
    selectedString = selectedString.ToLower()

    ' Declare the current size.
    Dim currentSize As Single

    ' Switch on the selected item. 
    Select Case selectedString

        ' If Bigger is selected, get the current size from the 
        ' Size property and increase it. Reset the font to the
        '  new size, using the current unit.
    Case "bigger"
