Question

delphi中如何获取汉字的拼音首字母?~!

如题
PS:在网上搜来而未经自己测试确认的就不必贴了,这个我也搜了不少了~!谢谢:)~

Answer 1

function GetPYIndexChar( hzchar:string):char;
begin //的到一个汉字的拼音头个字母
case WORD(hzchar[1]) shl 8 + WORD(hzchar[2]) of
$B0A1..$B0C4 : result := 'A';
$B0C5..$B2C0 : result := 'B';
$B2C1..$B4ED : result := 'C';
$B4EE..$B6E9 : result := 'D';
$B6EA..$B7A1 : result := 'E';
$B7A2..$B8C0 : result := 'F';
$B8C1..$B9FD : result := 'G';
$B9FE..$BBF6 : result := 'H';
$BBF7..$BFA5 : result := 'J';
$BFA6..$C0AB : result := 'K';
$C0AC..$C2E7 : result := 'L';
$C2E8..$C4C2 : result := 'M';
$C4C3..$C5B5 : result := 'N';
$C5B6..$C5BD : result := 'O';
$C5BE..$C6D9 : result := 'P';
$C6DA..$C8BA : result := 'Q';
$C8BB..$C8F5 : result := 'R';
$C8F6..$CBF9 : result := 'S';
$CBFA..$CDD9 : result := 'T';
$CDDA..$CEF3 : result := 'W';
$CEF4..$D188 : result := 'X';
$D1B9..$D4D0 : result := 'Y';
$D4D1..$D7F9 : result := 'Z';
else
result := char(0);
end;
end;

以下是我的原码100%可以
unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
Edit1: TEdit;
Edit2: TEdit;
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }

public
{ Public declarations }
end;
function GetPYIndexChar( hzchar:string):char;
var
Form1: TForm1;

implementation

{$R *.dfm}

function GetPYIndexChar( hzchar:string):char;
begin //的到一个汉字的拼音头个字母
case WORD(hzchar[1]) shl 8 + WORD(hzchar[2]) of
$B0A1..$B0C4 : result := 'A';
$B0C5..$B2C0 : result := 'B';
$B2C1..$B4ED : result := 'C';
$B4EE..$B6E9 : result := 'D';
$B6EA..$B7A1 : result := 'E';
$B7A2..$B8C0 : result := 'F';
$B8C1..$B9FD : result := 'G';
$B9FE..$BBF6 : result := 'H';
$BBF7..$BFA5 : result := 'J';
$BFA6..$C0AB : result := 'K';
$C0AC..$C2E7 : result := 'L';
$C2E8..$C4C2 : result := 'M';
$C4C3..$C5B5 : result := 'N';
$C5B6..$C5BD : result := 'O';
$C5BE..$C6D9 : result := 'P';
$C6DA..$C8BA : result := 'Q';
$C8BB..$C8F5 : result := 'R';
$C8F6..$CBF9 : result := 'S';
$CBFA..$CDD9 : result := 'T';
$CDDA..$CEF3 : result := 'W';
$CEF4..$D188 : result := 'X';
$D1B9..$D4D0 : result := 'Y';
$D4D1..$D7F9 : result := 'Z';
else
result := char(0);
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
edit2.Text:=GetPYIndexChar(edit1.Text);
end;

end.

引用xuleKnow的回答：
function GetPYIndexChar( hzchar:string):char;
begin //的到一个汉字的拼音头个字母
case WORD(hzchar[1]) shl 8 + WORD(hzchar[2]) of
$B0A1..$B0C4 : result := 'A';
$B0C5..$B2C0 : result := 'B';
$B2C1..$B4ED : result := 'C';
$B4EE..$B6E9 : result := 'D';
$B6EA..$B7A1 : result := 'E';
$B7A2..$B8C0 : result := 'F';
$B8C1..$B9FD : result := 'G';
$B9FE..$BBF6 : result := 'H';
$BBF7..$BFA5 : result := 'J';
$BFA6..$C0AB : result := 'K';
$C0AC..$C2E7 : result := 'L';
$C2E8..$C4C2 : result := 'M';
$C4C3..$C5B5 : result := 'N';
$C5B6..$C5BD : result := 'O';
$C5BE..$C6D9 : result := 'P';
$C6DA..$C8BA : result := 'Q';
$C8BB..$C8F5 : result := 'R';
$C8F6..$CBF9 : result := 'S';
$CBFA..$CDD9 : result := 'T';
$CDDA..$CEF3 : result := 'W';
$CEF4..$D188 : result := 'X';
$D1B9..$D4D0 : result := 'Y';
$D4D1..$D7F9 : result := 'Z';
else
result := char(0);
end;
end;

end.

delphi xe以上的版本都不支持，因为xe以上的版本支持双字节的，这种算法就失效了
