How to initialize double dimensional array with zero in c#

Question

I'm new to c#. I have two dimensional array. I want to initialize with 0.

Here is code. I have an error at Array.fill()

int N = elements;
int M N * 2;
int[,] amn = new int[M,N];
for(int i = 0; i < M; i++)
    Arrays.fill(amn[i], 0);

Answer 1

You don't need to do anything.

From Arrays (C# Programming Guide)

The default values of numeric array elements are set to zero, and reference elements are set to null.

So, when you write;

int[,] amn = new int[M,N];

all elements initalized to 0.

You can see on debugger;
