Delphi的DateToStr StrToDate格式灵活用法

2008-04-09 10:19

procedure TForm1.Button1Click(Sender: TObject);
var
   ADate: String;
   ADate2: TDate;
   AFormat, AFormat2: TFormatSettings;
begin
   AFormat.ShortDateFormat := 'ee/mm/dd';
   AFormat.DateSeparator := '/';
   ADate := '94/05/15';
   ADate2 := StrToDate( ADate, AFormat );
   AFormat2.ShortDateFormat := 'yyyy/mm/dd';
   AFormat2.DateSeparator := '/';
   ShowMessage( DateToStr( StrToDate( ADate, AFormat ), AFormat2 ) );
end;

其中,最重要的就是TFormatSettings这个类.

可以设置AFormat.shortDateFormat:='yyyymmdd'

DateToStr(ADate,Aformat)得到字符串就是类似20080409的字符了.

如果是'yymmdd'则为080409的字符
