【C#|c# 字符串与16进制ASCII码相到转换】1.普通字符串转16进制ASCII码

//普通字符串转16进制ASCII码 public static string toASCII(string code) { char[] cs = code.ToCharArray(); //先转字节数组 string Hstr = null; for (int l = 0; l < cs.Length; l++) { Hstr += ((int)cs[l]).ToString("X"); } //System.Console.WriteLine(Hstr); return Hstr; }

2.16进制ASCII码转普通字符串

public static string getASCIItoStr(string str) { byte[] bb = Hex2Bytes(str, false); System.Text.ASCIIEncoding asciiEncoding = new System.Text.ASCIIEncoding(); string strCharacter = asciiEncoding.GetString(bb); Console.WriteLine(strCharacter); return strCharacter; } //先将16进制ASCII码转字节数组 public static byte[] Hex2Bytes(string sHex, bool isExchange) { if (sHex == null || sHex.Length == 0) return null; sHex = sHex.Length % 2 == 0 ? sHex : "0" + sHex; byte[] bRtns = new byte[sHex.Length / 2]; for (int i = 0; i < bRtns.Length; i++) { if (isExchange) bRtns[bRtns.Length - 1 - i] = Convert.ToByte(sHex.Substring(i * 2, 2), 16); else bRtns[i] = Convert.ToByte(sHex.Substring(i * 2, 2), 16); } return bRtns; } }
