byte[] 转16进制字符串
方法一、
byte[] resultArray = new byte[]{1,2,3,4,5,6,7,8,9};
BitConverter.ToString(resultArray).Replace("-", "")
方法二、
/// <summary>
/// 字节数组转16进制字符串
/// </summary>
/// <param name="bytes"></param>
/// <returns></returns>
public static string byteToHexStr(byte[] bytes)
{
string returnStr = "";
if (bytes != null)
{
for (int i = 0; i < bytes.Length; i++)
{
returnStr += bytes[i].ToString("X2");
}
}
return returnStr;
}
16进制的字符串转为byte[]
/// <summary>
/// 将16进制的字符串转为byte[]
/// </summary>
/// <param name="hexString"></param>
/// <returns></returns>
public static byte[] StrToHexByte(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), 16);
return returnBytes;
