In This Topic

Represents the method that will handle the OnChange event of a PgSqlDependency.

Syntax

Visual Basic
C#

'Declaration
 
Public Delegate Sub OnChangeEventHandler( _
   ByVal sender As Object, _
   ByVal e As PgSqlTableChangeEventArgs _
)

public delegate void OnChangeEventHandler( 
   object sender,
   PgSqlTableChangeEventArgs e
)

Parameters

sender: The source of the event.
e: A PgSqlTableChangeEventArgs object that contains the event data.

Remarks

When you create a OnChange delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see "Events and Delegates" in the .NET Framework SDK documentation.
