Control.OnMouseClick(MouseEventArgs) Method


引发 MouseClick 事件。Raises the MouseClick event.

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



包含事件数据的 MouseEventArgsAn MouseEventArgs that contains the event data.


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.

OnMouseClick 方法还允许派生类对事件进行处理而不必附加委托。The OnMouseClick 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 OnMouseClick(MouseEventArgs) 时,一定要调用基类的 OnMouseClick(MouseEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnMouseClick(MouseEventArgs) in a derived class, be sure to call the base class's OnMouseClick(MouseEventArgs) method so that registered delegates receive the event.
