The PartyId property of the Connection class represents the unique identifier of the party that the user is currently part of. This property is useful for determining party membership and grouping users into parties based on their PartyId.

To access the PartyId property, you need an instance of the Connection class. This property is read-only and returns a SteamId object, which uniquely identifies the party.

Example usage:

Connection connection = ...; // Assume this is an existing connection
SteamId partyId = connection.PartyId;
// Use partyId to compare with other connections
