The source of event notification.

Time of the event occurrence - for conditions, time that the condition transitioned into the new state or sub-condition.

For example, if the event notification is for acknowledgment of a condition, this would be the time that the condition became acknowledged.

Event notification message describing the event.

Simple, Condition-Related, or Tracking event.

Internal value of one of constants.

Event category ID.

Standard and Vendor-specific event category codes.

Event severity (1..1000).

The name of the condition related to this event notification.

This property is used only for Condition-Related Events (see EventType).

The name of the current sub-condition, for multi-state conditions. For a single-state condition, this contains the condition name.

This property is used only for Condition-Related Events (see EventType).

New state of the condition: The condition is enabled.

This property is used only for Condition-Related Events (see EventType).

New state of the condition: The condition is active.

This property is used only for Condition-Related Events (see EventType).

New state of the condition: The condition is acknowledged.

This property is used only for Condition-Related Events (see EventType).

Quality associated with the condition.

This property is used only for Condition-Related Events (see EventType). Values are as defined for the OPC Quality Flags in the OPC Data Access Server specification.

This flag indicates that the related condition requires acknowledgment of this event.

This property is used only for Condition-Related Events (see EventType). The determination of those events which require acknowledgment is server specific. For example, transition into a LimitAlarm condition would likely require an acknowledgment, while the event notification of the resulting acknowledgment would likely not require an acknowledgment.

Time that the condition became active (for single-state conditions), or the time of the transition into the current sub-condition (for multi-state conditions).

This property is used only for Condition-Related Events (see EventType). This time is used by the client when acknowledging the condition.

Actor ID.

This property is used only for Tracking Events and for Condition-Related Events which are acknowledgment notifications (see EventType). For tracking events, this is the actor ID for the event notification. For condition-related events, this is the AcknowledgerID when the new state is acknowledged. If the AcknowledgerID is an empty string, the event was automatically acknowledged by the server. For other events, the value is an empty string.

Use this property with care, as its usability is limited. Its main use is for testing, and for non-library application code where just a single instance is sufficient. The default instance is not suitable for Windows Forms or similar environments, where a specific may be used with each form. We do not recommend to use the default instance for library code, due to conflicts that may arise if your library sets some instance parameters which may not be the same as what other libraries or th final application expects.

MP: During deserialization, SerializationInfo is passed to the class using the constructor provided for this purpose.

However, it is best practice to make the constructor protected unless the class is sealed, in which case the constructor should be marked private. The constructor should also perform thorough input validation. To avoid misuse by malicious code, the constructor should enforce the same security checks and permissions required to obtain an instance of the class using any other constructor.
