EventLogWatcher Class
Allows you to subscribe to incoming events. Each time a desired event is published to an event log, the EventRecordWritten event is raised, and the method that handles this event will be executed.
Assembly: System.Core (in System.Core.dll)
The EventLogWatcher type exposes the following members.
| Name | Description | |
|---|---|---|

EventLogWatcher(EventLogQuery) | Initializes a new instance of the EventLogWatcher class by specifying an event query. |
|
|
EventLogWatcher(String) | Initializes a new instance of the EventLogWatcher class by specifying the name or path to an event log. |
|
|
EventLogWatcher(EventLogQuery, EventBookmark) | Initializes a new instance of the EventLogWatcher class by specifying an event query and a bookmark that is used as starting position for the query. |
|
|
EventLogWatcher(EventLogQuery, EventBookmark, Boolean) | Initializes a new instance of the EventLogWatcher class by specifying an event query, a bookmark that is used as starting position for the query, and a Boolean value that determines whether to read the events that already exist in the event log. |
| Name | Description | |
|---|---|---|

Dispose() | Releases all the resources used by this object. |
|
Dispose(Boolean) | Releases the unmanaged resources used by this object, and optionally releases the managed resources. |
|
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|

MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |

|
EventRecordWritten | Allows setting a delegate (event handler method) that gets called every time an event is published that matches the criteria specified in the event query for this object. |
The instances of this class are created from EventLogQuery objects, which specify a query for the event subscription. When an event is logged that matches the criteria expressed in the query, then the EventRecordWritten event is raised.
