구문

‘선언
Public Sub Union ( _
    rectangle As Rect _
)
‘사용 방법
Dim instance As AnalysisRegion
Dim rectangle As Rect

instance.Union(rectangle)

public void Union(
    Rect rectangle
)

public:
void Union(
    Rect rectangle
)

public void Union(
    Rect rectangle
)

public function Union(
    rectangle : Rect
)

매개 변수

rectangle
형식: System.Windows.Rect
잉크 공간 좌표에서 결합할 사각형입니다.

설명

rectangle이 MinXY 및 MaxXY로 정의된 범위의 외부에 있는 경우 Union 메서드는 ArgumentOutOfRangeException을 throw합니다.

예제

이 예제에서는 두 AnalysisRegion 개체를 만듭니다. 그런 다음 Intersect, Union 및 Exclude 메서드를 사용하여 개체의 영역을 수정합니다.

' 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));
