<Button Name="btn3" FontSize="10.0"
Click="ChangeFontSize">
FontSize
</Button>
void ChangeFontSize(object sender, RoutedEventArgs e)
{
fsize = btn3.FontSize;
if (fsize == 16.0)
{
btn3.FontSize = 10.0;
btn3.Content = "FontSize";
}
else
{
btn3.FontSize = 16.0;
btn3.Content = "Control font size changes from 10 to 16.";
}
}
Private Sub ChangeFontSize(ByVal Sender As Object, ByVal e As RoutedEventArgs)
fsize = btn3.FontSize
If (fsize = 16.0) Then
btn3.FontSize = 10.0
btn3.Content = "FontSize"
Else
btn3.FontSize = 16.0
btn3.Content = "Control font size changes from 10 to 16."
End If
End Sub

XAML Values
double
Double
A string representation of a Double value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For example, a value of 1
is acceptable.
The same Double range restrictions that are mentioned in the Property Value section apply here.
qualifiedDouble
A double value as previously described that is followed by one of these unit declaration strings: px
, in
, cm
, pt
.
px
(default) is device-independent units (1/96th inch per unit)
in
is inches; 1in==96px
cm
is centimeters; 1cm==(96/2.54) px
pt
is points; 1pt==(96/72) px
Note In many cases a double may be set to "Auto," but a Control.FontSize does not render if set to "Auto".
