Question

Say I have a

List<double[]> x = new List<double[]>();
double[] item = new double[] {1.0,2.0,3.0};
x.add(item);
etc...

Is there a faster/cleaner way to get this into a double[,] then looping it:

double[,] arr = new double[x.Count,3];          
for (row = 0; row < x.Count; row++)
{
    for (col = 0; col < 3; col++)
        arr[row,col] = x[row][col];
}

Thanks.

No, there isn’t.

Multi-dimensional arrays are strange beasts and are not widely accepted or used in the BCL.

They’re also slow and should be avoided where possible.
