Binding.OnParse(ConvertEventArgs) Method


引发 Parse 事件。Raises the Parse event.

 virtual void OnParse(System::Windows::Forms::ConvertEventArgs ^ cevent);
protected virtual void OnParse (System.Windows.Forms.ConvertEventArgs cevent);
abstract member OnParse : System.Windows.Forms.ConvertEventArgs -> unit
override this.OnParse : System.Windows.Forms.ConvertEventArgs -> unit
Protected Overridable Sub OnParse (cevent As ConvertEventArgs)



一个包含事件数据的 ConvertEventArgsA ConvertEventArgs 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.

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