WebApplicationLifetimeEvent Constructor (String, Object, Int32)

Initializes the WebApplicationLifetimeEvent class using the supplied parameters.

Namespace:  System.Web.Management
Assembly:  System.Web (in System.Web.dll)

protected internal WebApplicationLifetimeEvent(
	string message,
	Object eventSource,
	int eventCode


Type: System.String

The message associated with the event.

Type: System.Object

The object that is the source of the event.

Type: System.Int32

The code associated with the event. When you implement a custom event, the event code must be greater than WebExtendedBase.

This constructor is used internally by the ASP.NET health-monitoring system. You will never use it to create an instance of the WebApplicationLifetimeEvent class, but you can call this constructor when implementing your own event type that inherits from this class.


The WebApplicationLifetimeEvent constructor is not intended to be used directly from your code. It is called by ASP.NET. You can call the WebApplicationLifetimeEvent constructor when deriving from the WebApplicationLifetimeEvent class.

The following code example shows how to use the WebApplicationLifetimeEvent in an ASP.NET custom health event. This code example is mainly intended to show the correct syntax to use.

// Invoked in case of events identified only by  
// their event code. 
public SampleWebApplicationLifetimeEvent(string msg, 
    object eventSource, int eventCode):
  base(msg, eventSource, eventCode)
    // Perform custom initialization.
    customCreatedMsg =
    string.Format("Event created at: {0}",
