Operation

As described above.

If the specified key already exists in the current instance, the specified value is added to the existing comma-separated list of values associated with the same key.

Attempting to assign the same value to an existing key adds a new value to that key, thus providing two (or more) copies of the same value associated with the key.

Note to Inheritors

Override this method to customize the default behavior in a type derived from the current type.
