Hi! Try this code:

FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.ReadWrite);
BinaryReader br = new BinaryReader(fs);
BinaryWriter bw = new BinaryWriter(fs);
fs.Seek(123, SeekOrigin.Begin); // start reading with 123 bytes offset
byte[] buf = br.ReadBytes(16);
for (int i=0; i<buf.Length; i++)
buf[i] ^= 128;
fs.Seek(123, SeekOrigin.Begin);
bw.Write(buf);
bw.Close(); // the underlying stream is closed as well
MessageBox.Show("Congratulations, you have ruined '"+filePath+"'!");
