delphibyte转string，delphi新手求助急等，怎样把array转st

Answer 1

如果是 带中文的String 转byte
function UniCode2GB(S: string): string;
var I: Integer;
begin
I := Length(S);
while I >= 4 do begin
try
Result := WideChar(StrToInt('$' + S[I - 3] + S[I - 2] + S[I - 1] + S[I])) + Result;
except end;
I := I - 4;
end;
end;
function GB2UniCode(GB: string): string;
var
s: string;
i, j, k: integer;
a: array[1..160] of char;
begin
s := '';
StringToWideChar(GB, @(a[1]), 500);
i := 1;
while ((a[i] <> #0) or (a[i + 1] <> #0)) do begin
j := Integer(a[i]);
k := Integer(a[i + 1]);
s := s + Copy(Format('%X ', [k * $100 + j + $10000]), 2, 4);
//S := S + Char(k)+Char(j);
i := i + 2;
end;
Result := s;
end;

var
s1,name:string;
ByteArr: array of byte;
s1 := GB2UniCode(‘张飒www’);
for I := 0 to round(Length(s1) / 2) - 1 do //以下是转string byte array
begin
ByteArr[I] := StrToint('$' + SubStr(s1, I * 2 + 1, 2));
end;

for I := 0 to len do //以下是byte array 转 string 支持中文
begin
Name := Name + IntToHex(ByteArr[I], 2);
end;
Name := UniCode2GB(Name);

以上是带中文的string 转 byte array 和 byte array 转 String
同样可以支持不带中文的string 和array转换
