範例

下列範例會透過 ReportObjects 集合的 Item 屬性依索引或名稱來擷取 ReportObject 物件，並轉換 ReportObject 為 LineObject。

[VJ#]

      private LineObject getLineObject(String reportObjectName)
      {
         LineObject line = null;
      
         try
         {
            line = (LineObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
         }
         catch (Exception e)
         {
         }
         return line;
      }
      

[Visual Basic]

      Private Function GetLineObject _
         (ByVal reportObjectName As String) As LineObject
      
         Dim line As LineObject
      
         If TypeOf _
            (Report.ReportDefinition.ReportObjects. _
            Item(reportObjectName)) Is LineObject Then
            line = _
               Report.ReportDefinition.ReportObjects. _
               Item(reportObjectName)
            GetLineObject = line
         Else : GetLineObject = Nothing
      End If
      

[C#]

      private LineObject GetLineObject(string reportObjectName)
      {
         LineObject line;
      
         line = Report.ReportDefinition.ReportObjects[reportObjectName]
            as LineObject;
         return line;
      }
