?

1 2 3 4 5 6 7 8 9

public string ByteArrayToHexString(byte[] data) { StringBuilder sb = new StringBuilder(); foreach(byte b in data) { sb.Append(((int)b).ToString("X2")); } return sb.ToString().ToUpper(); }

　　

 16进制转byte[]

private byte[] HexStrTobyte(string hexString)
{
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).Trim(), 16);
return returnBytes;
}

 byte[]转ASCII字符串

Encoding.ASCII.GetString(buffer,0,count);

Encoding.GetEncoding("GB2312").GetString(data);
