If you know the length of your collection and it is fixed, it is better to use an array. SyntaxД¬# Arrays are strongly typed, and work well as parameters. The ToArray() method copy the elements of the ArrayList to a new Object array. exampleД¬onsole.WriteLine('Count of elements of ArrayList ' + arrList.Count) Д¬onsole.WriteLine('Current capacity of ArrayList ' + arrList.Capacity) ДЄrrayList ToArray() method return an Object array containing copies of the elements of the ArrayList. If Count exceeds Capacity while adding elements, the capacity is automatically increased by reallocating the internal array before copying the old elements and adding the new elements. Capacity is always greater than or equal to Count. The Capacity property returns the number of elements that the ArrayList can store. The Count property returns the number of elements in an ArrayList, which is a non-generic collection that stores its length in a property called Count. SyntaxД¬onsole.WriteLine('ArrayList Elements after sort().') remove range of elements from arraylistД¬onsole.WriteLine('ArrayList Elements after RemoveRange().') ДЄrraylist Sort() method sorts the elements in the entire ArrayList.

How to add an Item in an ArrayList ? Syntax

Remove a range of elements from the ArrayList.

Remove an item from a specified position.

Insert an Item in a specified position in an ArrayList.

It is very flexible because we can add without any size information, that is it will grow dynamically and also shrink. ArrayList implements the IList interface using an array and very easily we can add, insert, delete, view etc. ArrayList contains a simple list of values.

ArrayList is one of the most flexible data structure from CSharp Collections.
