Exempel

Följande exempelkod visar användningen av en CodeAttachEventStatement för att koppla en händelsehanterare till en händelse.

// 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
