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

CodeAttachEventStatement()	Initializes a new instance of the CodeAttachEventStatement class.
CodeAttachEventStatement(CodeEventReferenceExpression, CodeExpression)	Initializes a new instance of the CodeAttachEventStatement class using the specified event and delegate.
CodeAttachEventStatement(CodeExpression, String, CodeExpression)	Initializes a new instance of the CodeAttachEventStatement class using the specified object containing the event, event name, and event-handler delegate.

Properties

EndDirectives	Gets a CodeDirectiveCollection object that contains end directives. (Inherited from CodeStatement)
Event	Gets or sets the event to attach an event-handler delegate to.
LinePragma	Gets or sets the line on which the code statement occurs. (Inherited from CodeStatement)
Listener	Gets or sets the new event-handler delegate to attach to the event.
StartDirectives	Gets a CodeDirectiveCollection object that contains start directives. (Inherited from CodeStatement)
UserData	Gets the user-definable data for the current object. (Inherited from CodeObject)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
