下列示例通过 FieldFormat 对象的 DateFieldFormat 属性检索 DateFieldFormat 对象。

  
[VJ#]
      private DateFieldFormat getDateFieldFormat
         (String reportObjectName)
      {
         FieldObject field;
         DateFieldFormat dateFormat = null;
         try
         {
            field = (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
            if (field.get_DataSource().get_ValueType() == FieldValueType.DateField)
               dateFormat = field.get_FieldFormat().get_DateFormat();
         }
         catch (Exception e)
         {
         }
         return dateFormat;
      }
      

  
[Visual Basic]
      Private Function GetDateFieldFormat _
         (ByVal reportObjectName As String) As DateFieldFormat
      
         Dim field As FieldObject
         Dim dateFormat As DateFieldFormat
      
         If TypeOf _
            (Report.ReportDefinition.ReportObjects. _
            Item(reportObjectName)) Is FieldObject Then
            field = _

               Item(reportObjectName)
            If field.DataSource.ValueType = _
               FieldValueType.DateField Then
               dateFormat = field.FieldFormat.DateFormat
               GetDateFieldFormat = dateFormat
            Else : GetDateFieldFormat = Nothing
            End If
         Else : GetDateFieldFormat = Nothing
         End If
      End Function

            {
               dateFormat = field.FieldFormat.DateFormat;
               return dateFormat;
            }
