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

  
[VJ#]
      private NumericFieldFormat getNumericFieldFormat
         (String reportObjectName)
      {
         FieldObject field;
         NumericFieldFormat numericFormat = null;
      
         try
         {
            field = (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
