[Visual Basic]

Public Class FieldObject
   Inherits ReportObject
   Implements IDisposable

範例

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

[VJ#]

      private FieldObject getFieldObject(String reportObjectName)
      {
         FieldObject field = null;
      
         try
         {
            field = (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
         }
         catch (Exception e)
         {
         }
         return field;
      }
      

[Visual Basic]

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

[C#]

      private FieldObject GetFieldObject(string reportObjectName)
      {
         FieldObject field;
      
         field =
            Report.ReportDefinition.ReportObjects[reportObjectName]
            as FieldObject;
         return field;
      }
