Hi How would I populate the elements of an array from a list

instead of this

C#

double[][] items ={
         new double[3] {.05,.05,0},
         new double[3] {0,0,1},
         new double[3]{.1,.05,1}};

Elements are in a arraylist
new double[3]{i,i++,i++}?

Something like this should work for you.

C#

ArrayList alist = new ArrayList();
alist.Add(new double[] { 3.0, 5.1, 4.8});
alist.Add(new double[] { 7.9, 9.1, 1.3 });
alist.Add(new double[] { 8.6, 6.2, 5.7 });

double[][] jagged = new double[alist.Count][];

for (int i = 0; i < alist.Count; i++)
{
    double[] a = (double[])alist[i];

    jagged[i] = a;
}

//test - show the array
for (int i = 0; i < jagged.Length; i++)
{
    for (int n = 0; n < jagged[i].Length; n++)
    {
        MessageBox.Show(jagged[i][n].ToString());
    }
}
