C# 8.0 对多维数组使用 Range

Question

在 C# 8.0 中，为什么我可以在一维数组上使用 range:

var oneDim = new int[5];
var oneDimSlice = oneDim[2..4];

但是不能在多维数组上使用它？

var twoDim = new int[5, 5];
var twoDimSlice = twoDim[2..4, 2..4];

Array has more nuanced behavior. Single dimension arrays support both indices and ranges. Multi-dimensional arrays don't. The indexer for a multi-dimensional array has multiple parameters, not a single parameter. Jagged arrays, also referred to as an array of arrays, support both ranges and indexers.

所以答案是否定的，但如果您有兴趣，可以使用锯齿状数组来完成。
