Explanation:
* MatchCollection
Represents the set of successful matches found by iteratively applying a regular expression pattern to the input
string.
The collection is immutable (read-only) and has no public constructor. The Regex.Matches method returns a
MatchCollection object.
* List<T>.Add Method
Adds an object to the end of the List<T>.

current instance. Note that the pointer to the current instance might not be sufficient for collections that wrap
other collections; those should return the underlying collection’s SyncRoot property.
