Two dimensional array slice in C#

I'm looking to slice a two dimensional array in C#.

I have double[2,2] prices and want to retrieve the second row of this array. I've tried prices[1,], but I have a feeling it might be something else.

Thanks in advance.

There's no direct "slice" operation, but you can define an extension method like this:

public static IEnumerable<T> SliceRow<T>(this T[,] array, int row)
{
    for (var i = 0; i < array.GetLength(0); i++)
    {
        yield return array[i, row];
    }
}

double[,] prices = ...;

double[] secondRow = prices.SliceRow(1).ToArray();
