1.byte[] 转换16进制字符串
1.1 BitConverter方式
var str = DateTime.Now.ToString();
var encode = Encoding.UTF8;
var bytes = encode.GetBytes(str);
var hex = BitConverter.ToString(bytes, 0).Replace("-", string.Empty).ToLower();
Console.WriteLine(hex);
1.2 StringBuilder方式
var str = DateTime.Now.ToString();
var encode = Encoding.UTF8;
var bytes = encode.GetBytes(str);
StringBuilder ret = new StringBuilder();
foreach (byte b in bytes)
{
//{0:X2} 大写
ret.AppendFormat("{0:x2}", b);
}
var hex = ret.ToString();
Console.WriteLine(hex);
2.16进制字符串转换 byte[]
var inputByteArray = new byte[hex.Length / 2];
for (var x = 0; x < inputByteArray.Length; x++)
{
var i = Convert.ToInt32(hex.Substring(x * 2, 2), 16);
inputByteArray[x] = (byte)i;
}
str = encode.GetString(inputByteArray);
Console.WriteLine(str);标签：substr date ring substring bst enc bsp encoding converter
