C# | Add an object to the end of the ArrayList
ArrayList represents an ordered collection of an object that can be indexed individually. It is basically an alternative to an array. It also allows dynamic memory allocation, adding, searching and sorting items in the list. ArrayList.Add(Object) method adds an object to the end of the ArrayList.
Properties of ArrayList Class:
- Elements can be added or removed from the Array List collection at any point in time.
- The ArrayList is not guaranteed to be sorted.
- The capacity of an ArrayList is the number of elements the ArrayList can hold.
- Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.
- It also allows duplicate elements.
- Using multidimensional arrays as elements in an ArrayList collection is not supported.
public virtual int Add (object value);
