1、数字转16进制

var a=1;
var b=Convert.ToString(a,16);

2、字符转16进制

private static string StringToHexString(string s, Encoding encode)
        {
            byte[] b = encode.GetBytes(s);//按照指定编码将string编程字节数组
            string result = string.Empty;
            for (int i = 0; i < b.Length; i++)
            {
                result += Convert.ToString(b[i], 16);
            }
            return result;
        }

3、byte[]转16进制

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;
        }

4、16进制转byte[]

private static byte[] StrToByte(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;

        }
