How convert string to pixels

Question

I have TextBlock with some Text="AAAAAAAA", FontFamily="Arial", FontSize="16". How I can convert Text to WPF pixels?

Answer 1

You could use FormattedText for measuring:

FormattedText formattedText = new FormattedText(
    "AAAAAAAA",
    CultureInfo.CurrentCulture,
    FlowDirection.LeftToRight,
    new Typeface("Arial"), 16, Brushes.Black
);
MessageBox.Show(formattedText.Width.ToString());
