| Name | Description | |
|---|---|---|
![]() | CodeRemoveEventStatement() | Initializes a new instance of the CodeRemoveEventStatement class. |
![]() | CodeRemoveEventStatement(CodeEventReferenceExpression^, CodeExpression^) | Initializes a new instance of the CodeRemoveEventStatement class with the specified event and event handler. |
![]() | CodeRemoveEventStatement(CodeExpression^, String^, CodeExpression^) | Initializes a new instance of the CodeRemoveEventStatement class using the specified target object, event name, and event handler. |

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 = gcnew CodeDelegateCreateExpression( gcnew CodeTypeReference( "System.EventHandler" ),gcnew CodeThisReferenceExpression,"OnMouseEnter" ); // Creates a remove event statement that removes the delegate from the TestEvent event. CodeRemoveEventStatement^ removeEvent1 = gcnew CodeRemoveEventStatement( gcnew CodeThisReferenceExpression,"TestEvent",mouseEnterDelegate ); // A C# code generator produces the following source code for the preceeding example code: // this.TestEvent -= new System.EventHandler(this.OnMouseEnter);
