Aggiornamento: novembre 2007

Limita l'area dell'oggetto AnalysisRegion alla parte dell'area che non interseca l'oggetto AnalysisRegion specificato.

Spazio dei nomi: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)

Sintassi

'Dichiarazione
Public Sub Exclude ( _
    regionToExclude As AnalysisRegion _
)
'Utilizzo
Dim instance As AnalysisRegion
Dim regionToExclude As AnalysisRegion

instance.Exclude(regionToExclude)

public void Exclude(
    AnalysisRegion regionToExclude
)

public:
void Exclude(
    AnalysisRegion^ regionToExclude

public function Exclude(
    regionToExclude : AnalysisRegion
)

Parametri

regionToExclude
Tipo: System.Windows.Ink.AnalysisRegion
Oggetto AnalysisRegion che descrive l'area da escludere.

Note

Se le due aree non si intersecano, AnalysisRegion non viene modificato.

Esempi

In questo esempio vengono creati due oggetti AnalysisRegion. Vengono utilizzati i metodi Intersect, Union e Exclude per modificare le aree degli oggetti.

' Create an infinite AnalysisRegion.
Dim theFirstAnalysisRegion As New AnalysisRegion()
' Create a finite AnalysisRegion.
Dim theSecondAnalysisRegion As New AnalysisRegion(New Rect(100, 100, 200, 200))
' Extend an AnalysisRegion using the Union method and an AnalysisRegion.
theFirstAnalysisRegion.Union(theSecondAnalysisRegion)

' Extend an AnalysisRegion using the Union method and a rectangle.
theFirstAnalysisRegion.Union(New Rect(100, 100, 200, 200))

' Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion)

' Restrict an AnalysisRegion using the Intersect method and a rectangle.
theFirstAnalysisRegion.Intersect(New Rect(100, 100, 200, 200))

' Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion)

' Modify an AnalysisRegion using the Exclude method and a rectangle.
theFirstAnalysisRegion.Exclude(New Rect(100, 100, 200, 200))

// Create an infinite AnalysisRegion.
AnalysisRegion theFirstAnalysisRegion =
    new AnalysisRegion();

// Create a finite AnalysisRegion.
AnalysisRegion theSecondAnalysisRegion =
    new AnalysisRegion(
        new Rect(100, 100, 200, 200));

// Extend an AnalysisRegion using the Union method and an AnalysisRegion.
theFirstAnalysisRegion.Union(theSecondAnalysisRegion);

// Extend an AnalysisRegion using the Union method and a rectangle.
theFirstAnalysisRegion.Union(new Rect(100, 100, 200, 200));

// Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion);

// Restrict an AnalysisRegion using the Intersect method and a rectangle.
theFirstAnalysisRegion.Intersect(new Rect(100, 100, 200, 200));

// Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion);

// Modify an AnalysisRegion using the Exclude method and a rectangle.
theFirstAnalysisRegion.Exclude(new Rect(100, 100, 200, 200));
