C#中如何将字符串转换byte[]，同时如何将byte[]换成字符串?
C#中如何将字符串转换byte[]，同时如何将byte[]换成字符串!
1
string to byte []
string str = "abcd" ;
byte[] bytes
=
System.Text.Encoding.ASCII.GetBytes(str);
-------------------------------------------------------------------------------------------------------------
2
byte[] to string
byte[] bytes = new byte[255]
;
string str =
System.Text.Encoding.ASCII.GetString(bytes,0,bytes.Length);
--------------------------------------------------------------------------------------------
在附上二个方法：
private static byte[]
HexStringToByteArray(string s)
{
s = s.Replace(" ",
"");
byte[] buffer = new byte[s.Length / 2];
for
(int i = 0; i < s.Length; i += 2)
buffer[i / 2] =
(byte)Convert.ToByte(s.Substring(i, 2), 16);
return
buffer;
}
private string ByteArrayToHexString(byte[] data)
{
StringBuilder sb = new StringBuilder(data.Length *
3);
foreach (byte b in data)
sb.Append(Convert.ToString(b, 16).PadLeft(2, '0').PadRight(3, '
'));
return sb.ToString().ToUpper();
}
