Jun 28, 2015 · A byte is 8 bits, and an array of byte, is an array of bytes... It really is that simple. The thing to keep in mind is that char and byte are different. In old C style, a char and byte were basically the same thing. In .NET, characters are Unicode and can be anywhere from 8-32 bits per character. This is where encoding comes into play.

Jun 26, 2012 · In Java 6, there is a method doing exactly what you want: private static final byte[] CDRIVES = javax.xml.bind.DatatypeConverter.parseHexBinary ...

Mar 8, 2009 · How do I convert a byte[] to a string? Every time I attempt it, I get System.Byte[] instead of the value. Also, how do I get the value in Hex instead of a decimal?

Nov 12, 2019 · Usually this happens if something is wrong with the byte array. File.WriteAllBytes("filename.PDF", Byte[]); This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten. Asynchronous implementation of this is also available.

The protobuf MessageLite Interface provides toByteArray() and toByteString() methods. If ByteString is an immutable byte[], would the byte representation of a message represented by both ByteString and byte[] be the same? Sort of. If you call toByteArray() you'll get the same value as if you were to call toByteString().toByteArray().

For example, to get the nth byte of the integer I found this response: int x = (number >> (8*n)) & 0xff; Even though I understand the bit shifting component (shifting 8n digits to the right) I don't see where the & and 0xff come in, and what they mean aside from & is a bitwise AND operator.

This example reads 6 bytes into a byte array and writes it to another byte array. It does an XOR operation with the bytes so that the result written to the file is the same as the original starting values. The file is always 6 bytes in size, since it writes at position 0.
