範例

下列範例會透過 FieldFormat 物件的 DateTimeFormat 屬性來擷取 DateTimeFieldFormat 物件。

[VJ#]

      private DateTimeFieldFormat getDateTimeFieldFormat
         (String reportObjectName)
      {
         FieldObject field;
         DateTimeFieldFormat dateTimeFormat = null;
         try
         {
            field = (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
            if (field.get_DataSource().get_ValueType() ==
               FieldValueType.DateTimeField)
               dateTimeFormat = field.get_FieldFormat().get_DateTimeFormat();
         }
         catch (Exception e)
         {
         }
         return dateTimeFormat;
      }
      

[Visual Basic]

      Private Function GetDateTimeFieldFormat _
         (ByVal reportObjectName As String) As DateTimeFieldFormat
      
         Dim field As FieldObject
         Dim dateTimeFormat As DateTimeFieldFormat
      
         If TypeOf _
            (Report.ReportDefinition.ReportObjects. _
            Item(reportObjectName)) Is FieldObject Then
            field = _
               Report.ReportDefinition.ReportObjects. _
               Item(reportObjectName)
            If field.DataSource.ValueType = _
               FieldValueType.DateTimeField Then
               dateTimeFormat = field.FieldFormat.DateTimeFormat
               GetDateTimeFieldFormat = dateTimeFormat
            Else : GetDateTimeFieldFormat = Nothing
            End If
         Else : GetDateTimeFieldFormat = Nothing
         End If
      End Function
      

[C#]

      private DateTimeFieldFormat GetDateTimeFieldFormat
         (string reportObjectName)
      {
         FieldObject field;
         DateTimeFieldFormat dateTimeFormat;
         field =

            as FieldObject;
         if (field != null)
         {
            if (field.DataSource.ValueType ==
               FieldValueType.DateTimeField)
            {
               dateTimeFormat = field.FieldFormat.DateTimeFormat;
               return dateTimeFormat;
            }
            else return null;
         }
