2015年6月28日 · 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.

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

2012年10月17日 · Step back. Look at the bigger picture. You're stuck converting byte[] to Byte[] or vice versa because of Java's strict type casing with something like this. List< Byte> or List<Byte[]> Now you have byte[] and Byte[] and have to convert. This will help. Keep all your byte[]s in a list like this: List<byte[]> instead of List< Byte> or List<Byte[]>.

2009年3月8日 · 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?

2011年7月2日 · When overridden in a derived class, decodes all the bytes in the specified byte array into a string. Namespace: System.Text Assembly: mscorlib (in mscorlib.dll) Syntax. public virtual string GetString(byte[] bytes) Parameters. bytes Type: System.Byte[] The byte array containing the sequence of bytes to decode. Return Value. Type: System.String

2011年12月28日 · Because gustafc's answer has a very important point: String(byte[]) constructor uses the System default encoding to convert the byte array into String characters. One should not assume that a 0x63 byte value is mapped to the letter 'c'. For example, in UTF-16 the letter 'c' is represented by 2 encoding bytes, not one.

Without getting into two's complement: 2^8 (since a byte is 8 digits and can have 1 of 2 values) = 256, so the most individual values a byte can represent is 256. so, representing the numbers -128 to -1 is half our range. I believe the question here is …

2016年12月2日 · In C#, byte is the data type for 8-bit unsigned integers, so a byte[] should be an array of integers who are between 0 and 255, just like an char[] is an array of characters. But most of time when I encounter byte[], I see byte[] is used as a contiguous chunk of memory for storing raw representation of data.

2022年2月18日 · These two-byte portions come from the BMP numeric range, but are guaranteed by the Unicode standard to be invalid as BMP characters. In addition, since UTF-16 has two bytes as its basic unit, it is affected by endianness. To compensate, a reserved byte order mark can be placed at the beginning of a data stream which indicates endianness. Thus ...

2012年6月22日 · If you have "random" byte from photography, I think that you will get exceptions sometime: T:System.ArgumentException: The byte array contains invalid Unicode code points. In the documentation of Json.NET it is declared that a …
