CodeAttachEventStatement can be used to represent a statement that adds an event-handler delegate for an event. The Event property indicates the event to attach the event handler to. The Listener property indicates the event handler to attach.

The following example code demonstrates use of a CodeAttachEventStatement to attach an event handler with an event.

// Defines a delegate creation expression that creates an EventHandler delegate pointing to a method named TestMethod.
CodeDelegateCreateExpression createDelegate1 = new CodeDelegateCreateExpression( 
new CodeTypeReference( "System.EventHandler" ), new CodeThisReferenceExpression(), "TestMethod" );                                
// Attaches an EventHandler delegate pointing to TestMethod to the TestEvent event.
CodeAttachEventStatement attachStatement1 = new CodeAttachEventStatement( new CodeThisReferenceExpression(), "TestEvent", createDelegate1 );

// A C# code generator produces the following source code for the preceeding example code: 

//     this.TestEvent += new System.EventHandler(this.TestMethod);
