Question

The array should contain 3 regions.
Each region should include two numbers :

region 1 for example will contain 3,4
region 2 5,5
region 3 23,100

Answer 1

// Three-dimensional array. 
int[, ,] array3D = new int[,,] { { { 1, 2, 3 }, { 4, 5, 6 } }, 
                             { { 7, 8, 9 }, { 10, 11, 12 } } };

Which was taken from here, which I found using Google and searching with this string, “multidimensional arrays in C#”.
