C#拦截系统消息的方法Application.AddMessageFilter
C#拦截系统消息的方法Application.AddMessageFilter Application.AddMessageFilter这个方法可以接收系统发出的消息: 首先定义一个类,继承IMessageFilter接口代码如下:
internal class MyMessager : IMessageFilter
{
//截取消息，进行处理
public bool PreFilterMessage(ref System.Windows.Forms.Message m)
{
switch (m.Msg)
{
case 513: //拦截左键单击事件
MessageBox.Show("左键被拦截！"); return true;
case 516: //拦截左键单击事件
MessageBox.Show("右键被拦截！");
return true;
default: return false; //返回false则消息未被裁取，系统会处理
}
}
} 然后在窗体load事件中加入Application.AddMessageFilter方法
private void Form1_Load(object sender, EventArgs e)
{
Application.AddMessageFilter(new MyMessager());
}
以上转自：http://www.cnblogs.com/whtydn/archive/2009/04/30/1447117.html
此方法并不能够调用全部的消息，可能只调用线程消息序列的，具体没搞明白，可参考http://www.eggheadcafe.com/software/aspnet/32211162/not-getting-all-window-messages-from-imessagefilter.aspx
所以建议使用WndProc() 重载，MessageFilter 在MSDN上还有说会降低效率的。
