namespace MemoryAllocation
{
class Program
{
static void Main(string[] args)
{
int size = 2;

while (size > 0)
{
Byte[] b = new Byte[size];

for (int i = 0; i<size; ++i)
b[i] = 13;
size *= 2;
}

}
}
} 

推荐答案

对我来说，while 循环似乎很可疑-因为size如果您继续这样加倍，它将永远不会低于零！

That while loop looks suspicious to me - It''ll just keep allocating more and more memory until you run out, since size will never get below zero if you keep doubling it like that!

基于这些，您的内存不足-此处 [

Based on these, you are running out of memory - here[^] and here[^].
