Event Dictionaries (nEventProperties) provide an accessible and flexible way to store any number of message properties for delivery within an Universal Messaging Events.

Event Dictionaries are quite similar to a hash table, supporting primitive types, arrays, and nested dictionaries.

Universal Messaging filtering allows subscribers to receive only specific subsets of a channel's events by applying the server's advanced filtering capabilities to the contents of each event's dictionary.

Nirvana event dictionaries can facilitate the automated purging of data from channels through the use of Publish Keys.

In this C# code snippet, we assume we want to publish an event containing the definition of a bond, say, with a name of "bond1":

Note that in this example code, we also create a new Universal Messaging Event object (nConsumeEvent) to make use of our Event Dictionary (nEventProperties).
