Examples
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 = gcnew CodeDelegateCreateExpression( gcnew CodeTypeReference( "System.EventHandler" ),gcnew CodeThisReferenceExpression,"TestMethod" );
// Attaches an EventHandler delegate pointing to TestMethod to the TestEvent event.
CodeAttachEventStatement^ attachStatement1 = gcnew CodeAttachEventStatement( gcnew CodeThisReferenceExpression,"TestEvent",createDelegate1 );
// A C# code generator produces the following source code for the preceeding example code:
// this.TestEvent += new System.EventHandler(this.TestMethod);
// 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);
' Defines a delegate creation expression that creates an EventHandler delegate pointing to TestMethod.
Dim createDelegate1 As New CodeDelegateCreateExpression(New CodeTypeReference("System.EventHandler"), New CodeThisReferenceExpression(), "TestMethod")
' Attaches an EventHandler delegate pointing to TestMethod to the TestEvent event.
Dim attachStatement1 As New CodeAttachEventStatement(New CodeThisReferenceExpression(), "TestEvent", createDelegate1)
' A Visual Basic code generator produces the following source code for the preceeding example code:
' AddHandler TestEvent, AddressOf Me.TestMethod
Remarks
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.
Constructors
