示例

下面的示例测试 AnalysisRegion (theFirstAnalysisRegion) 所表示的区域的范围。

' Check whether the AnalysisRegion is empty, infinite, or neither.
If theFirstAnalysisRegion.IsEmpty Then
    ' Insert code here for an empty AnalysisRegionBase.
ElseIf theFirstAnalysisRegion.IsInfinite Then
    ' Insert code here for an infinite AnalysisRegionBase.
Else
    ' Insert code here for a non-empty, finite AnalysisRegionBase.
End If

            // Check whether the AnalysisRegionBase is empty, infinite, or neither.
            if (theFirstAnalysisRegion.IsEmpty)
            {
                // Insert code here for an empty AnalysisRegionBase.
            }
            else if (theFirstAnalysisRegion.IsInfinite)
            {
                // Insert code here for an infinite AnalysisRegionBase.
            }
            else
            {
                // Insert code here for a non-empty, finite AnalysisRegionBase.
            }
