CodeRemoveEventStatement Class

Represents a statement that removes an event handler.

Namespace:  System.CodeDom
Assembly:  System (in System.dll)

public class CodeRemoveEventStatement : CodeStatement

CodeRemoveEventStatement can be used to represent a statement that removes an event handler for an event.

The Event property specifies the event to remove the event handler from. The Listener property specifies the event handler to remove.

The following example demonstrates use of a CodeRemoveEventStatement to remove a delegate from an event.

// Creates a delegate of type System.EventHandler pointing to a method named OnMouseEnter.
CodeDelegateCreateExpression mouseEnterDelegate = new CodeDelegateCreateExpression( new CodeTypeReference("System.EventHandler"), new CodeThisReferenceExpression(), "OnMouseEnter" );
// Creates a remove event statement that removes the delegate from the TestEvent event.
CodeRemoveEventStatement removeEvent1 = new CodeRemoveEventStatement( new CodeThisReferenceExpression(), "TestEvent", mouseEnterDelegate );

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

//     this.TestEvent -= new System.EventHandler(this.OnMouseEnter);
