The area with which to combine.

Заметки

If either area is infinite, the new area is also infinite.

Примеры

The example uses Exclude, Intersect, and Union to modify the area of an existing AnalysisRegionBase, named theFirstAnalysisRegionBase.

' 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);
