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

LINQ doesn't work particularly well with multi-dimensional arrays.

Jagged arrays aren't too bad:

var array = Enumerable.Range(0, 10)
                      .Select(x => Enumerable.Repeat('x', 10).ToArray())
                      .ToArray();

... but rectangular arrays don't have any specific support. Just use loops.

(Note the use of Enumerable.Repeat as a somewhat simpler approach to creating the 1-dimensional array, btw.)
