C # multidimensional arrays and nested arrays

usingSystem;namespaceAbc.e.f//equivalent to the following hierarchical nesting of the wording. And this type of writing, regardless of whether the namespace ABC has been defined, or whether the namespace E has been defined{    classMYTESTX {Static voidMain (string[] args) {            int[,] matrix =New int[2,5];//multidimensional arrays. Just increase from dimension, not array nesting. Kind of like a multidimensional matrix .            int[] MT1 =New int[2][];//An array of arrays, with two elements, each of which is an array. Equivalent to an array of nested arrays. Sort of like a binary chain list .mt1[0] =New int[5]; mt1[1] =New int[4]; int[,,,] Mt =New int[2,3,4,5];//Array of arrays, multiple nested arrays.         }    }}
