Fill a C# 2d array with some value

Question

I've got this program where I'm creating a character array that's filed with a given character, and I was wondering if there is a faster way to do so than the nested for loops that I've been using, like the numpy.zeros command in python. Like for an array arr,

char[,] arr = new char array[3, 4]

Is there a faster way to fill it than:

        for (int i=0; i<3; i++)
        {
            for (int j=0; j<4; j++)
            {
                arr[i, k] = 'a';
            }
        }

Answer 1

The below will create a 5 by 5 char[][] with a single value, J in this case.

char[][] result = Enumerable.Repeat(Enumerable.Repeat('J', 5).ToArray(),5).ToArray();
