C# Array Length

Description

Array Length gets a 32-bit integer that represents the total number of elements in all the dimensions of the Array.

Syntax

Array.Length has the following syntax.


public int Length { get; }

Example

The following example uses the Length property to get the total number of elements in an array. It also uses the GetUpperBound method to determine the number of elements in each dimension of a multidimensional array.


using System;// w w  w.  j a  v  a 2s  . co m

public class MainClass
{
   public static void Main(){
      String[] array1d = { "zero", "one", "two", "three" };
      ShowArrayInfo(array1d);

      String[,] array2d= { { "zero", "0" }, { "one", "1" }, 
                           { "two", "2" }, { "three", "3"},
                           { "four", "4" }, { "five", "5" } };
      ShowArrayInfo(array2d);                             
   }

   private static void ShowArrayInfo(Array arr)
   {
      Console.WriteLine("Length of Array:      {0,3}", arr.Length);
      Console.WriteLine("Number of Dimensions: {0,3}", arr.Rank);

      if (arr.Rank > 1) {
         for (int dimension = 1; dimension <= arr.Rank; dimension++)
            Console.WriteLine("   Dimension {0}: {1,3}", dimension, 
                              arr.GetUpperBound(dimension - 1) + 1);
      }
      Console.WriteLine();
   }
}

The code above generates the following result.
