Collection<T>.Add(T) method is used to add an object to the end of the Collection<T>.
public void Add (T item);
Here, item is the object to be added to the end of the Collection<T>. The value can be null for reference types.
Below given are some examples to understand the implementation in a better way:
The number of elements in myColl are : 5 The elements in myColl are : A B C D E
The number of elements in myColl are : 4 The elements in myColl are : 2 3 4 5
- Collection<T> accepts null as a valid value for reference types and allows duplicate elements.
- This method is an O(1) operation.
