Question

In C# how do i initialize

int[][] test;

I don’t want to use int[,] instead. I am asking specifically how to initialize the above. The obvious = int[1][1] does not work. I tried a few different ways with no luck and [][] is not really google-able unfortunately (unless its possible!?)

Answer 1

It’s called jagged arrays if you want to Google it.

Basically you can initialize the first dimension in the traditional way :

int[][] test = new int[23][];

And you manually initialize the others :

for (int i = 0; i < test.Length; ++i)
    test[i] = new int[42];
