Articolo
10/29/2008

Aggiornamento: novembre 2007

Limita l'area di AnalysisRegion alla parte dell'area che non interseca il rettangolo specificato.

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

Sintassi

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

instance.Exclude(rectangleToExclude)

public void Exclude(
    Rect rectangleToExclude
)

public:
void Exclude(
    Rect rectangleToExclude
)

public void Exclude(
    Rect rectangleToExclude
)

public function Exclude(
    rectangleToExclude : Rect
)

Parametri

rectangleToExclude
Tipo: System.Windows.Rect
Area da escludere.

Note

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

Il metodo Exclude genera un'eccezione ArgumentOutOfRangeException se i limiti di rectangleToExclude non sono compresi tra i valori definiti da MinXY e MaxXY.

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));
