Csharp/CSharp Tutorial/Data Type/Bitwise NOT
bitwise NOT for hexadecimal
<source lang="csharp">class MainClass {
public static void Main() { byte byte1 = 0x9a; // binary 10011010, decimal 154 byte byte2 = 0xdb; // binary 11011011, decimal 219 byte result; System.Console.WriteLine("byte1 = " + byte1); System.Console.WriteLine("byte2 = " + byte2); result = (byte) ~byte1; System.Console.WriteLine("~byte1 = " + result); }
}</source>
byte1 = 154 byte2 = 219 ~byte1 = 101
