Get dimension length, c# arrays

Question

Assert.Equals(6, cols);

Answer 1

You can use GetLength() method of array that let you know what is the length of each dimension.

var rows = arr.GetLength(0);
var columns = arr.GetLength(1);

Just to make clear, it gets the size, so in your example rows will be 2.
