예제

다음 예제에서는에 대 한 캐싱 힌트 값을 검색 하는 방법을 보여 줍니다 DrawingBrush .The following example shows how to retrieve the caching hint values for a DrawingBrush.

// 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
