2d array use in c#

Questions & Answers
1

I have a 2d array like this.

int[ , ] array1 = new int[2, 3] {{10, 20, 30}, {40, 50, 60}};

I’d like to move all elements of array1[0] at once like this.

int array2 = array1[0];

or want to use it like this.

for(int i = 0; i < array1[0].Length; i++) {
…
}

But I get a error msg saying ‘Wrong number of indexes 1' inside [], expected 2’.

Is it impossible??? If so, is there any methods to do it?
Thanks in advance for anyone’s help.

for(int i = 0; i < array1.GetLength(1); i++)
{
Debug.Log(array1[0,i]);
}

Since you are looking for the second dimension size you need to pass 1 (the y value).
