C#操作Byte数组和十六进制进行互转

一、Byte 数组转十六进制字符串


 	     /// <summary>
 	         /// Byte 数组转十六进制字符串
 	         /// </summary>
 	         /// <param name="Bytes"></param>
 	         /// <returns></returns>
 	         public static string ByteToHex(byte[] Bytes)
 	         {
 	             string str = string.Empty;
 	             foreach (byte Byte in Bytes)
 	             {
 	                 str += String.Format("{0:X2}", Byte) + " ";
 	             }
 	             return str.Trim();
 	         }

二、字符串转十六进制Byte数组


 	         /// <summary>
 	         /// 字符串转十六进制Byte数组
 	         /// </summary>
 	         /// <param name="hexString"></param>
 	         /// <returns></returns>
 	         public static byte[] strToToHexByte(string hexString)
 	         {
 	             try
 	             {
 	                 hexString = hexString.Replace(" ", "");
 	                 if ((hexString.Length % 2) != 0)
 	                     hexString += " ";
 	                 byte[] returnBytes = new byte[hexString.Length / 2];
 	                 for (int i = 0; i < returnBytes.Length; i++)
 	                     returnBytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
 	                 return returnBytes;
 	             }
 	             catch
 	             {
 	                 return null;
 	             }
 	 
 	         }
