C# | Removing first occurrence of object from Collection<T>
Collection<T>.Remove(T) is used to remove the first occurrence of a specific object from the Collection<T>.
public bool Remove (T item);
Here, item is the object to remove from the Collection<T>. The value can be null for reference types.
Return Value: True if item is successfully removed, otherwise, False. This method also returns False if item was not found in the original Collection<T>.
Below given are some examples to understand the implementation in a better way:
Count : 5 A B C D E Count : 4 A B D E
Count : 5 2 3 4 4 5 Count : 4 2 3 4 5
Note: This method performs a linear search. Therefore this method is an O(n) operation, where n is Count.
