DELPHI 字符转16进制、16进制转字符

function TForm1.myStrToHex(s:string):string; //字串转16进制
var
    TmpStr:string;
    i:integer;
begin
    TmpStr:='';
    for i:=1 to Length(s)do
    begin
        TmpStr:=TmpStr+IntToHex(ord(s[i]),2);
    end;
    Result:=TmpStr;
end;

 

function TForm1.myHexToStr(s:string):string; //16进制转字串
var
    HexS,TmpStr:string;
    i:Integer;
    a:Byte;
begin
    HexS:=s;
    if Length(HexS) mod 2=1 then
    begin
        HexS:=HexS+'0';
    end;
    TmpStr:='';
    for i:=1 to(Length(HexS)div 2)do
    begin
        a:=StrToInt('$'+HexS[2*i-1]+HexS[2*i]);
        TmpStr:=TmpStr+Chr(a);
    end;
    Result:=TmpStr;
end;
