delphi日期格式MM|dd|yy转MM/dd/yy错误

Question

我需要转换当前日期，其格式为:

     MM|dd|yy     ---  12|09|11

我需要将格式转换为:

     MM/dd/yy     --12/09/11

当前系统日期分隔符是:

   -'|'

我使用的代码为:

  var
     sDateOne : TDate ;
 begin
   Label1.Caption:=datetostr(now);              {this display as 12|09|11}
   ShortDateFormat:='MM/dd/yy';
   DateSeparator:='/';
   sDateOne:=StrToDate(Label1.Caption);
   FormatDateTime('MM/dd/yy',sDateOne );
   Label2.Caption:=datetostr(sDateOne);         {this i want as 12/09/11 }
 end;

但我在 sDateOne:=StrToDate(Label1.Caption); 行收到错误

请告诉我如何转换日期格式并显示？

这是您的代码的更正版本:

var
  DateOne: TDate;
  LocalFormatSettings: TFormatSettings;
begin
  Label1.Caption := datetostr(now);              {this display as 12|09|11}
  DateOne := StrToDate(Label1.Caption);
  GetLocaleFormatSettings(LOCALE_SYSTEM_DEFAULT, LocalFormatSettings);
  LocalFormatSettings.DateSeparator := '/';
  Label2.Caption := FormatDateTime('MM/dd/yy', DateOne, LocalFormatSettings); {this i want as 12/09/11 }
end;
