Csharp/CSharp Tutorial/Data Type/Bitwise NOT

bitwise NOT for hexadecimal

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);
  }
}

byte1 = 154
byte2 = 219
~byte1 = 101

The bitwise NOT

using System; 
class Example { 
  public static void Main() { 
    sbyte b = -34; 
 
    for(int t=128; t > 0; t = t/2) { 
      if((b & t) != 0) 
          Console.Write("1 ");  
      if((b & t) == 0) 
          Console.Write("0 ");  
    } 
    Console.WriteLine(); 
 
    // reverse all bits 
    b = (sbyte) ~b; 
 
    for(int t=128; t > 0; t = t/2) { 
      if((b & t) != 0) 
         Console.Write("1 ");  
      if((b & t) == 0) 
         Console.Write("0 ");  
    } 
  } 
}
