字符串转化成十六进制输出StrToHex(Delphi版、C#版)//注意:Delphi2010以下版本默认的字符编码是ANSI,VS2010的默认编码是UTF-8,delphi版字符串事先须经过AnsiToUtf8()转码才能跟C#版得到的十六进制字符串显示结果一致。
Delphi版:
function StrToHex(AStr: string): string;vari : Integer;ch:char;begin
Result:=''; for i:=1 to length(AStr) do begin ch:=AStr[i]; Result:=Result+IntToHex(Ord(ch),2); end;end;复制代码
//***************************************************
C#版
public string StrToHex(string str) { string strResult; byte[] buffer = Encoding.GetEncoding("utf-8").GetBytes(str); strResult = ""; foreach (byte b in buffer) { strResult += b.ToString("X2");//X是16进制大写格式 } return strResult; }
Delphi 十六进制字符串转化成字符串输出HexToStr(Delphi版、C#版)
//注意:Delphi2010以下版本默认的字符编码是ANSI,VS2010的默认编码是UTF-8,delphi版得到的字符串须经过Utf8ToAnsi()转码才能跟C#版得到的字符串显示结果一致。
//Delphi版:
function HexToStr(str: string): string; function HexToInt(hex: string): integer; var i: integer; function Ncf(num, f: integer): integer; var i: integer; begin Result := 1; if f = 0 then exit; for i := 1 to f do result := result * num; end; function HexCharToInt(HexToken: char): integer; begin if HexToken > #97 then HexToken := Chr(Ord(HexToken) - 32); Result := 0; if (HexToken > #47) and (HexToken < #58) then { chars 0....9 } Result := Ord(HexToken) - 48 else if (HexToken > #64) and (HexToken < #71) then { chars A....F } Result := Ord(HexToken) - 65 + 10; end; begin result := 0; hex := ansiuppercase(trim(hex)); if hex = '' then exit; for i := 1 to length(hex) do result := result + HexCharToInt(hex[i]) * ncf(16, length(hex) - i); end;var s, t: string; i, j: integer; p: pchar;begin s := ''; i := 1; while i < length(str) do begin t := str[i] + str[i + 1]; s := s + chr(hextoint(t)); i := i + 2; end; result := s;end;
C#版:
/// /// 从16进制转换成汉字 /// /// /// 编码,如"utf-8","gb2312" /// public string HexToStr(string hex, string charset) { if (hex == null) throw new ArgumentNullException("hex"); hex = hex.Replace(",", ""); hex = hex.Replace("\n", ""); hex = hex.Replace("\\", ""); hex = hex.Replace(" ", ""); if (hex.Length % 2 != 0) { hex += "20";//空格 } // 需要将 hex 转换成 byte 数组。 byte[] bytes = new byte[hex.Length / 2];
for (int i = 0; i < bytes.Length; i++) { try { // 每两个字符是一个 byte。 bytes[i] = byte.Parse(hex.Substring(i * 2, 2), System.Globalization.NumberStyles.HexNumber); } catch { // Rethrow an exception with custom message. throw new ArgumentException("hex is not a valid hex number!", "hex"); } } System.Text.Encoding chs = System.Text.Encoding.GetEncoding(charset); return chs.GetString(bytes); }
