2D Array. Set all values to specific value

Question

To assign specific value to 1D array I\'m using LINQ like so:

        int[] nums = new int[20];
        nums = (from i in nums select 1).ToArray()         


        

Answer 1

One way you could do this is like so:

// Define a little function that just returns an IEnumerable with the given value
static IEnumerable Fill(int value)
{
    while (true) yield return value;
}

// Start with a 1 dimensional array and then for each element create a new array 10 long with the value of 2 in
var ar = new int[20].Select(a => Fill(2).Take(10).ToArray()).ToArray();
