推荐答案

声明数组时，必须知道长度，因为数组被视为连续的内存块，必须一起分配.
如果要使用直到填满才知道长度的数组，请考虑使用List< T>.而是使用Add方法仅继续添加元素-以后可以根据需要使用ToArray方法获取数组内容.

When you declare an array, the length has to be known, as the array is considered as a contiguous block of memory, which has to be allocated together.
If you want to use an array where you do not know the length until you have filled it, consider using a List<T> instead and use the Add method to just keep adding elements - you can use the ToArray method later to get the array content if you need it.
