Control.OnMouseUp(MouseEventArgs) Method

Definition

引发 MouseUp 事件。Raises the MouseUp event.

protected:
 virtual void OnMouseUp(System::Windows::Forms::MouseEventArgs ^ e);
protected virtual void OnMouseUp (System.Windows.Forms.MouseEventArgs e);
abstract member OnMouseUp : System.Windows.Forms.MouseEventArgs -> unit
override this.OnMouseUp : System.Windows.Forms.MouseEventArgs -> unit
Protected Overridable Sub OnMouseUp (e As MouseEventArgs)

Parameters

e
MouseEventArgs

一个包含事件数据的 MouseEventArgsA MouseEventArgs that contains the event data.

Remarks

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息,请参阅处理和引发事件For more information, see Handling and Raising Events.

OnMouseUp 方法还允许派生类对事件进行处理而不必附加委托。The OnMouseUp method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

在派生类中重写 OnMouseUp(MouseEventArgs) 时,一定要调用基类的 OnMouseUp(MouseEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnMouseUp(MouseEventArgs) in a derived class, be sure to call the base class's OnMouseUp(MouseEventArgs) method so that registered delegates receive the event.
