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.
Example
using System;
class Program {
static void Main() {
int[,,] arr = new int[3,4,5]
Console.WriteLine("Dimensions of Array : " + arr.Rank);
}
}
