Visual Basic (Declaration)
Public Overrides NotOverridable Sub Add ( _ key As TKey, _ value As TValue _ )

Visual C++
public: virtual void Add ( TKey key, TValue value ) override sealed

Equality between keys is determined by the comparison instance or delegate used to create the dictionary.

Adding an key and value takes time O(log N), where N is the number of keys in the dictionary.
