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

May I suggest a new extension method.

public static class TwoDArrayExtensions
{
    public static void ClearTo(this int[,] a, int val)
    {
        for (int i=a.GetLowerBound(0); i <= a.GetUpperBound(0); i++)
        {
            for (int j=a.GetLowerBound(1); j <= a.GetUpperBound(1); j++)
            {
                a[i,j] = val;
            }
        }
    }
}

Use it like this:

var nums = new int[10, 10];
nums.ClearTo(1);
