'宣告
Public Sub Union ( _
    left As Integer, _

'用途
Dim instance As AnalysisRegionBase
Dim left As Integer
Dim top As Integer
Dim right As Integer
Dim bottom As Integer

instance.Union(left, top, right, bottom)

public void Union(
    int left,
    int top,
    int right,
    int bottom
)

public:
void Union(
    int left, 
    int top, 
    int right, 
    int bottom
)

public void Union(
    int left,
    int top,
    int right,
    int bottom
)

public function Union(
    left : int, 
    top : int, 
    right : int, 
    bottom : int
)

參數

left
型別：System.Int32
要與之結合的矩形左界限，以筆墨空間座標表示。

top
型別：System.Int32
要與之結合的矩形頂端界限，以筆墨空間座標表示。

right
型別：System.Int32
要與之結合的矩形右界限，以筆墨空間座標表示。

bottom
型別：System.Int32
要與之結合的矩形底端界限，以筆墨空間座標表示。

備註

所有參數都會使用 HIMETRIC 單位。

如果任一個區域為無限，新區域也是無限。

範例

這個範例使用 Exclude、Intersect 和 Union 修改現有 AnalysisRegionBase (名為 theFirstAnalysisRegionBase) 的區域。

' Extend an AnalysisRegionBase using the Union method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase)

' Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500)

' Restrict an AnalysisRegionBase using the Intersect method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase)

' Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000)

' Restrict an AnalysisRegionBase using the Exclude method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase)

' Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500)

// Extend an AnalysisRegionBase using the Union method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase);

// Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500);

// Restrict an AnalysisRegionBase using the Intersect method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase);

// Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000);

// Restrict an AnalysisRegionBase using the Exclude method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase);

// Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500);
