问题描述
这基本上是这个问题的重述：Java:多维数组与一维的。但对于C＃。
This is basically a restatement of this question: Java: Multi-dimensional array vs. One-dimensional. but for C#.
我有意义的存储为网格元素的集合量。
我应该使用一个数组[X * Y]或数组[X] [Y]？
I have a set amount of elements that make sense to store as a grid.Should I use a array[x*y] or a array[x][y]?
编辑：哦，所以有一维数组[X * Y]，多维数组[X，Y]和交错数组[X] [Y]，我可能想锯齿状
Oh, so there are one dimensional array[x*y], multidimensional array[x,y] and jagged array[x][y], and I probably want jagged?
推荐答案
有在C＃中很多优点，使用的（数组[] [] ）。他们实际上往往会跑赢多维数组。
There are many advantages in C# to using jagged arrays (array[][]). They actually will often outperform multidimensional arrays.
话虽这么说，我会亲自使用多维或锯齿状排列，而不是一个单一的维数组，因为这更加紧密地问题空间相匹配。使用一维数组增加复杂的实现，并不提供真正的实惠，特别是相对于一个二维数组的时候，作为在内部，它仍然是一个单独的内存块。
That being said, I would personally use a multidimensional or jagged array instead of a single dimensional array, as this matches the problem space more closely. Using a one dimensional array is adding complexity to your implementation that does not provide real benefits, especially when compared to a 2D array, as internally, it's still a single block of memory.
