C# 8.0 using Range for multidimensional arrays

Question

In C# 8.0, why can I use range on single dimensional arrays:

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

But can not use it on multi dimensional arrays ?

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.

so the answer is no, but it is possible to do it with jagged arrays if you are interested.
