這個類別可以讓您擷取資訊，並設定繼承自 ReportObject 類別的泛用格式選項。

範例

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

[VJ#]

      private ChartObject getChartObject(String reportObjectName)
      {
         ChartObject chart = null;
      
         try
         {
            chart =
               (ChartObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
         }
         catch (Exception e)
         {
         }
         return chart;
      }
      

[Visual Basic]

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

[C#]

      private ChartObject GetChartObject(string reportObjectName)
      {
         ChartObject chart;
      
         chart =
            Report.ReportDefinition.ReportObjects[reportObjectName]
            as ChartObject;
         return chart;
      }
