To get the rank of a three-dimensional array, use the Rank property.
Set a three-dimensional array.
int[,,] arr = new int[3,4,5]
Now get the rank.
arr.Rank
Let us see the complete code.
using System; class Program { static void Main() { int[,,] arr = new int[3,4,5] Console.WriteLine("Dimensions of Array : " + arr.Rank); } }
