Obtaining the Most Significant or Least Significant Bits of a Number
using System;
using System.Data;
class Class1{

short num = 25;
Console.WriteLine(GetMSB(number));
Console.WriteLine(GetConvertMSB(number));
Console.WriteLine(GetLSB(number));
Console.WriteLine(GetConvertLSB(number));
Console.WriteLine(GetMSB(num));
Console.WriteLine(GetLSB(num));
}
public static int GetMSB(int value)
{
return (int)(value & 0xFFFF0000);
}
public static int GetConvertMSB(int value)
{
return (value & Convert.ToInt32("11111111111111110000000000000000", 2));
}
public static int GetLSB(int intValue)
{
return (intValue & 0x0000FFFF);
}
public static int GetConvertLSB(int intValue)
{
return (intValue & Convert.ToInt32("11111111111111110000000000000000", 2));
}
public static int GetMSB(short intValue)
{

Using the Bitwise Complement Operators with Various Data Types
using System;
using System.Data;
class Class1{
static void Main(string[] args){
uint x = 0x01001001;
uint XComp = ~x;
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);
char x3 = (char)1; // Problem
Console.WriteLine("~x3 = " + ~x3);
sbyte x5 = 1;
Console.WriteLine("~x5 = " + ~x5);
uint IntResult = (uint)~x;
Console.WriteLine("IntResult = " + IntResult);
byte ByteResult = (byte)~y;
Console.WriteLine("ByteResult = " + ByteResult);
}
