Span and two dimensional Arrays

Question

Is it possible to use the new System.Memory Span struct with two dimensional arrays of data?

double[,] testMulti = 
    {
        { 1, 2, 3, 4 },
        { 5         


        

Answer 1

Perhaps there's more success to be had working with a jagged array instead of a multidimensional array.

double[][] testMulti = 
    {
        new double[] { 1, 2, 3, 4 },
        new double[] { 5, 6, 7, 8 },
        new double[] { 9, 9.5f, 10, 11 },
        new double[] { 12, 13, 14.3f, 15 }
    };

Span span = testMulti.AsSpan(2, 1);
Span slice = span[0].AsSpan(1, 2);

foreach (double d in slice)
    Console.WriteLine(d);

slice[0] = 10.5f;

Console.Write(string.Join(", ", testMulti[2]));

Console.ReadLine();

OUTPUT

9.5
10
9, 10.5, 10, 11
