範例

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

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