Using the Bitwise Complement Operators with Various Data Types

<source lang="csharp"> using System; using System.Data;

     Console.WriteLine("~x = " + ~x);
     sbyte B1 = sbyte.MinValue;  
     sbyte B2 = sbyte.MaxValue;
     Console.WriteLine("B1|B2 = " + (((byte)B1|(byte)B2)));
     ushort x2 = 0x00000001;           // Problem
     Console.WriteLine("~x2 = " + ~x2);
     byte y = 1;                       // Problem
     //byte B = ~y;
     Console.WriteLine("~y = " + ~y);
