int result1= 66 << 1;//正数的左移位运算规则,左移一位乘以2,右移移位除以2  左移两位乘以4,三位乘以8,4位乘以16,右移则相反;            int result2 = -66<< 1; //负数的移位运算在最高位补1;运算规则和正数一样            Console.WriteLine("正数移位"+result1+"............"+"负数移位"+result2);

 

当声明重载C#移位运算符时，第一个操作数的类型必须总是包含运算符声明的类或结构，并且第二个操作数的类型必须总是 int,如：

class Program    {        static void Main(string[] args)        {            ShiftClass shift1 = new ShiftClass(5, 10);            ShiftClass shift2 = shift1 << 2;            ShiftClass shift3 = shift1 >> 2;            Console.WriteLine("{0} << 2 结果是:{1}", shift1.valA,  shift2.valA);            Console.WriteLine("{0} << 2 结果是:{1}", shift1.valB,shift2.valB);            Console.WriteLine("{0} >> 2 结果是:{1}", shift1.valA,  shift3.valA);            Console.WriteLine("{0} >> 2 结果是:{1}", shift1.valB, shift3.valB);            Console.ReadLine();        }        public class ShiftClass        {           public int valA;           public int valB;            public ShiftClass(int valA, int valB)            {                this.valA = valA;                this.valB = valB;            }            public static ShiftClass operator <<(ShiftClass shift, int count)            {                int a = shift.valA << count;                int b = shift.valB << count;                return new ShiftClass(a, b);            }            public static ShiftClass operator >>(ShiftClass shift, int count)            {                int a = shift.valA >> count;                int b = shift.valB >> count;                return new ShiftClass(a, b);            }        }    }
