public static double GetCacheInvalidationThresholdMaximum (System.Windows.DependencyObject target);
[<System.Windows.AttachedPropertyBrowsableForType(typeof(System.Windows.Media.TileBrush))>]
static member GetCacheInvalidationThresholdMaximum : System.Windows.DependencyObject -> double
Public Shared Function GetCacheInvalidationThresholdMaximum (target As DependencyObject) As Double

参数

示例

下面的示例演示如何检索缓存 DrawingBrush提示值。

// Get the caching hint option for the brush.
CachingHint cachingHint = RenderOptions.GetCachingHint(drawingBrush);

if (cachingHint == CachingHint.Cache)
{
    // Get the minimum and maximum relative sizes for regenerating the tiled brush.
    double minimum = RenderOptions.GetCacheInvalidationThresholdMinimum(drawingBrush);
    double maximum = RenderOptions.GetCacheInvalidationThresholdMaximum(drawingBrush);

    // Perform action based on cache values...
}
' Get the caching hint option for the brush.
Dim cachingHintOpt As CachingHint = RenderOptions.GetCachingHint(drawingBrush)

If cachingHintOpt = CachingHint.Cache Then
    ' Get the minimum and maximum relative sizes for regenerating the tiled brush.
    Dim minimum As Double = RenderOptions.GetCacheInvalidationThresholdMinimum(drawingBrush)
    Dim maximum As Double = RenderOptions.GetCacheInvalidationThresholdMaximum(drawingBrush)

    ' Perform action based on cache values...
End If
