Refference Array Inside Array (C)

So I have this array:

int[][] Array= new int[][] {
new int[] {1,2},
new int[] {2,2},
new int[] {2,1}
}

If I try sizeof(Array) it works, but sizeof(Array[0]) does not. Why?

 

sizeof returns you the size of a certain type:

If you want to know the number of elements in an array, you need to call length for the array:

And I'd suggest using a int[,] Array instead of an int[][], assuming each rank is the same length

Then you get the length with myArray.GetLength(int dimension)

 

Thank you ! really helpful!

@hpjohn Does that work from Array[][][]?
Also why did you suggest that?

 

Personal preferrence, on syntax niceness.
But read this and judge for yourself

int[x][y][z] can be int[x,y,z]
