示例

以下示例返回 BooleanFieldFormat 对象。

  
[VJ#]
      private BooleanFieldFormat getBooleanFieldformat
         (String reportObjectName)
      {
         FieldObject field;
         BooleanFieldFormat booleanFormat = null;
         try
         {
            field =
               (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
            if (field.get_DataSource().get_ValueType() ==
               FieldValueType.BooleanField)
               booleanFormat = field.get_FieldFormat().get_BooleanFormat();
         }
         catch (Exception e)
         {
         }
         return booleanFormat;
      }

         Dim field As FieldObject

            Else : GetBooleanFieldformat = Nothing
            End If
         Else : GetBooleanFieldformat = Nothing
         End If
      End Function
