C# 移位运算符

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);

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);
