C#检测鼠标移动消息

当C#窗口上有其它控件时,窗口本身检测不到消息。
1、使用WndProc、MouseMove不行，比如

 protected override void WndProc(ref Message m)
         {
             switch (m.Msg)
             {
                 case WM_MOUSEMOVE:
                     Debug.Write(string.Format("CurrentDate:{0}", DateTime.Now) + Environment.NewLine);
                     break;
             }
             base.WndProc(ref m);
         }

2、使用PreFilterMessage

 public partial class Form1 : Form, IMessageFilter
 {
 //构造函数里增加
 public Form1()
 {
     InitializeComponent();
     Application.AddMessageFilter(this);

 }
 public bool PreFilterMessage(ref Message msg)
 {
      const int WM_MOUSEMOVE = 0x200;
      if (msg.Msg == WM_MOUSEMOVE)
      {
           TestPopUp();
      }
      return false;
 }
 }
