Examples

The following code example demonstrates how to use the Font constructor and the Size, SizeInPoints, and Unit properties. This example is designed to be used with a Windows Form that contains a ComboBox named ComboBox1 that is populated with the strings "Bigger" and "Smaller". Paste the following code into the form and associate the ComboBox1_SelectedIndexChanged method with the SelectedIndexChanged event of the ComboBox control.

private void ComboBox1_SelectedIndexChanged(System.Object sender, 
    System.EventArgs e)
{

    // Cast the sender object back to a ComboBox.
    ComboBox ComboBox1 = (ComboBox) sender;

    // Retrieve the selected item.
    string selectedString = (string) ComboBox1.SelectedItem;

    // Convert it to lowercase.
    selectedString = selectedString.ToLower();

    // Declare the current size.
    float currentSize;

    // Switch on the selected item. 
    switch(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":
            currentSize = Label1.Font.Size;
            currentSize += 2.0F;
            Label1.Font = new Font(Label1.Font.Name, currentSize, 
                Label1.Font.Style, Label1.Font.Unit);

            // If Smaller is selected, get the current size, in points,
            // and decrease it by 1.  Reset the font with the new size
            // in points.
            break;
        case "smaller":
            currentSize = Label1.Font.SizeInPoints;
            currentSize -= 1;
            Label1.Font = new Font(Label1.Font.Name, currentSize, 
                Label1.Font.Style);
            break;
    }
}
