Xamarin.Forms: How to use custom Fonts in C# Code

Question

I want to use some custom Fonts (.ttf) in my Xamarin.Forms Application. I added the two Fonts in both Projects(Android/iOS):

Now in the XAML-Page , I added the Fonts to the ResourceDictionary . It's also possible to use the Fonts, but just in the XAML-File :

<Label Text="Test" FontFamily="{StaticResource FONT}" FontSize="Medium"/>

But how can I use this font in the C# Code?

Answer 1

The Device.RuntimePlatform property can be used to set different font names on each platform.

if (Device.RuntimePlatform == Device.iOS)
{
    label.FontFamily = "xxx.ttf";
}

else if (Device.RuntimePlatform == Device.Android)
{
    label.FontFamily = "xxx.ttf#xxx";
}

else
{
    label.FontFamily = "Assets/Fonts/xxx.ttf#xxx";
}
