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.RankLet us see the complete code.Exampleusing System; class Program {    static void Main() {       int[,,] arr = new int[3,4,5]       Console.WriteLine("Dimensions of Array : " + arr.Rank);    } }

Bypass elements in an array and return the remaining elements using the SkipWhile() method.The following is our array −int[] marks = { 45, 88, 55, 90, 95, 85 };Now, let’s skip the elements greater than or equal to 60. The condition we have set using Lambda Expression.IEnumerable selMarks = marks.AsQueryable().OrderByDescending(s ... Read More
