在C中操纵纽约球和更小的球#

你可以使用 BitVector32 操作32位整数中的位,以及 BitArray 有一个代表一组布尔变量的位数组。

此外,编写几个函数来操作单个位也很容易:

public bool GetBitValue(int integer, int bit) {
    return (integer & (1 << bit)) != 0; 
}

public bool SetBitValue(ref int integer, int bit, bool value) {
    if (value)
        integer |= 1 << bit;
    else
        integer &= ~(1 << bit);
}

图书馆真的不必要

uint myVar = 257;
const uint SOME_FLAG_A = 256 // 100000000
const uint SOME_FLAG_B = 16  // 000010000
const uint SOME_FLAG_C = 1   // 000000001

if(myVar & SOME_FLAG_A == SOME_FLAG_A)
   Console.WriteLine("Bit A is set!");
else
   Console.WriteLine("Bit A is not set.");

if(myVar & SOME_FLAG_B == SOME_FLAG_B)
   Console.WriteLine("Bit B is set!");
else
   Console.WriteLine("Bit B is not set.");

myVar = myVar | SOME_FLAG_B;

if(myVar & SOME_FLAG_B == SOME_FLAG_B)
   Console.WriteLine("Bit B is set!");
else
   Console.WriteLine("Bit B is not set.");

if(myVar & SOME_FLAG_C == SOME_FLAG_C)
   Console.WriteLine("Bit C is set!");
else
   Console.WriteLine("Bit C is not set.");
