示例

下列示例通过 ReportObjects 集合的 Item 属性，按名称检索 ReportObject 对象，并将 ReportObject 转换为 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;
      }
