SysUtils.CompareStr、SysUtils.CompareText - 字符串比较

CompareStr 区分大小写; CompareText 不区分大小写. 举例:

---

var

  s1,s2: string;

  i: Integer;

begin

  s1 := 'abc';

  s2 := 'adc';

  i := CompareStr(s1,s2);

  ShowMessage(IntToStr(i));  {-2}



  i := CompareText(s1,s2);

  ShowMessage(IntToStr(i));  {-2}



  s1 := 'abc';

  s2 := 'ABC';

  i := CompareStr(s1,s2);    {CompareStr 区分大小写}

  ShowMessage(IntToStr(i));  {32}



  i := CompareText(s1,s2);   {CompareText 不区分大小写}

  ShowMessage(IntToStr(i));  {0}

end;
