private void SetLinearGradientUnderline()
{
    // Create an underline text decoration. Default is underline.
    TextDecoration myUnderline = new TextDecoration();

    // Create a linear gradient pen for the text decoration.
    Pen myPen = new Pen();
    myPen.Brush = new LinearGradientBrush(Colors.Yellow, Colors.Red, new Point(0, 0.5), new Point(1, 0.5));
    myPen.Brush.Opacity = 0.5;
    myPen.Thickness = 1.5;
    myPen.DashStyle = DashStyles.Dash;
    myUnderline.Pen = myPen;
    myUnderline.PenThicknessUnit = TextDecorationUnit.FontRecommended;

    // Set the underline decoration to a TextDecorationCollection and add it to the text block.
    TextDecorationCollection myCollection = new TextDecorationCollection();
    myCollection.Add(myUnderline);
    TextBlock3.TextDecorations = myCollection;
}
' Use a linear gradient pen for the underline text decoration.
Private Sub SetLinearGradientUnderline()
    ' Create an underline text decoration. Default is underline.
