答案是肯定的,它就是 WndProc 函数。所有的消息都要经过这个函数处理。...Windows 程序有两种消息,一种是队列消息,它通过 DispatchMessage 函数分发给 WndProc 函数,像鼠标消息、键盘消息,Timer消息都是这类消息。...另一种是非队列消息,它是系统函数直接发送给 WndProc 函数的,像窗口的创建与消毁消息,WM_COMMON消息等等都是非队列消息。...() 上面一节我也介绍了 WndProc 是 Windows 程序的消息中心。...它说 WndProc 就是 WndProc,它说 WindowProc 就是 WindowProc。

WndProc 在.NET框架类库中的System.Windows.Forms命名空间中微软采用面对对象的方式重新定义了Message。...protected override void WndProc(ref System.Windows.Forms.Message e); 对于每个Form来说,我们都可以重写该方法,该方法的参数就是上面提到的...,所以如果希望底层能处理相关的消息,需要通过base.WndProc传递到父类继续调用。...下面就是一个代码示例来展示控制如果当前的消息是鼠标左键点击,则弹出MessageBox展示“WndProc MouseClick”: protected override void WndProc(ref...MouseClick"); return; } base.WndProc(ref m); } IMessageFilter 除了上述的WndProc之外,其实更加便于处理应该的实现
