Delphi的DateToStr StrToDate格式灵活用法

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
