Why does a Boolean consume 4 bytes and a char 2 bytes in the .NET framework? A Boolean should take up 1bit or at least be smaller than a char.
推荐答案
是内存对齐的问题.4 字节变量的工作速度比 2 字节变量快.这就是为什么你应该使用 int 而不是 byte 或 short 作为计数器等的原因.
It is a question of memory alignment. 4-byte variables work faster than 2-byte ones. This is the reason why you should use int instead of byte or short for counters and the like.
You should use 2-byte variables only when memory is a bigger concern than speed. And this is the reason why char (which is Unicode in .NET) takes two bytes instead of four.
