How to find the length and rank of a jagged array in C#?

Firstly, set a jagged array.

int[][] arr = new int[][] {    new int[] {       0,       0    }, new int[] {       1,       2    },    new int[] {       2,       4    }, new int[] {       3,       6    }, new int[] {       4,       8    } };

Now, use the GetLowerBound(), GetUpperBound() and Rank property to get the lenth and rank of the array as shown in the following code −

Example

 Live Demo

using System; public class Program {    public static void Main() {       int[][] arr = new int[][] {          new int[] {             0,             0          }, new int[] {             1,             2          },          new int[] {             2,             4          }, new int[] {             3,             6          }, new int[] {             4,             8          }       };       // Length       Console.WriteLine("Length:" + arr.Length);       Console.WriteLine("Upper Bound: {0}", arr.GetUpperBound(0).ToString());       Console.WriteLine("Lower Bound: {0}", arr.GetLowerBound(0).ToString());       Console.WriteLine("Dimensions of Array : " + arr.Rank);    } }

Output

Length:5 Upper Bound: 4 Lower Bound: 0 Dimensions of Array : 1
