示例

以下示例演示如何创建简单的文本效果，并通过该属性将其应用于文本RunTextEffects。

// Create and configure a simple color animation sequence.  Timespan is in 100ns ticks.
ColorAnimation blackToWhite = new ColorAnimation(Colors.White, Colors.Black, new Duration(new TimeSpan(100000)));
blackToWhite.AutoReverse = true;
blackToWhite.RepeatBehavior = RepeatBehavior.Forever;

// Create a new brush and apply the color animation.
SolidColorBrush scb = new SolidColorBrush(Colors.Black);
scb.BeginAnimation(SolidColorBrush.ColorProperty, blackToWhite);

// Create a new TextEffect object; set foreground brush to the previously created brush.
TextEffect tfe = new TextEffect();
tfe.Foreground = scb;
// Range of text to apply effect to (all).
tfe.PositionStart = 0;
tfe.PositionCount = int.MaxValue;

// Create a new text run, and add the previously created text effect to the run's effects collection.
Run flickerRun = new Run("Text that flickers...");
flickerRun.TextEffects = new TextEffectCollection();
flickerRun.TextEffects.Add(tfe);

' Create and configure a simple color animation sequence.  Timespan is in 100ns ticks.
Dim blackToWhite As New ColorAnimation(Colors.White, Colors.Black, New Duration(New TimeSpan(100000)))
blackToWhite.AutoReverse = True
blackToWhite.RepeatBehavior = RepeatBehavior.Forever

' Create a new brush and apply the color animation.
Dim scb As New SolidColorBrush(Colors.Black)
scb.BeginAnimation(SolidColorBrush.ColorProperty, blackToWhite)

' Create a new TextEffect object; set foreground brush to the previously created brush.
Dim tfe As New TextEffect()
tfe.Foreground = scb
' Range of text to apply effect to (all).
tfe.PositionStart = 0
tfe.PositionCount = Integer.MaxValue

' Create a new text run, and add the previously created text effect to the run's effects collection.
Dim flickerRun As New Run("Text that flickers...")
flickerRun.TextEffects = New TextEffectCollection()
flickerRun.TextEffects.Add(tfe)

注解

默认情况下，此属性设置为 null 且不 TextEffectCollection 与之关联。 在添加任何文本效果之前，请创建一个新 TextEffectCollection 效果并将其分配给此属性。
