将硬盘驱动器串行字符串写入二进制文件
|
我有一个简单的函数，可以从C：\\驱动器获取硬盘驱动器序列号，并将其放入字符串中：
ManagementObject disk = new ManagementObject(\"win32_logicaldisk.deviceid=\\\"C:\\\"\");
disk.Get();
string hdStr = Convert.ToString(disk[\"VolumeSerialNumber\"]);
string constructor2 = \"16342D1F4A61BC\";
string StrValue = \"\";
while (constructor2.Length > 0)
{
StrValue += System.Convert.ToChar(System.Convert.ToUInt32(constructor2.Substring(0, 2), 16)).ToString();
// Remove from the hex object the converted value
constructor2 = constructor2.Substring(2, constructor2.Length - 2);
}
FileStream writeStream;
try
{
writeStream = new FileStream(Path.GetDirectoryName(Application.ExecutablePath) + \"\\\\license.mgr\", FileMode.Create);
BinaryWriter writeBinay = new BinaryWriter(writeStream);
writeBinay.Write(StrValue);
writeBinay.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}

使用以下帮助程序：public static byte[] ToBytesFromHexa(string text) { if (text == null) throw new ArgumentNullException(\"text\"); List<byte> bytes = new List<byte>(); bool low = false; byte prev = 0; for (int i = 0; i < text.Length ; i++) { byte b = GetHexaByte(text[i]); if (b == 0xFF) continue; if (low) { bytes.Add((byte)(prev * 16 + b)); } else { prev = b; } low = !low; } return bytes.ToArray(); } public static byte GetHexaByte(char c) { if ((c >= \'0\') && (c <= \'9\')) return (byte)(c - \'0\'); if ((c >= \'A\') && (c <= \'F\')) return (byte)(c - \'A\' + 10); if ((c >= \'a\') && (c <= \'f\')) return (byte)(c - \'a\' + 10); return 0xFF; }掸牛浓疗
