範例

下列範例會測試由 AnalysisRegion (變數名稱為 theFirstAnalysisRegion) 表示的區域範圍。

' 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.
            }
