C#无边框窗体代码问题

private Point mouse_offset; 
private void form_MouseDown(object sender, EventArgs e) 
{ 

mouse_offset = new Point(-e.X, -e.Y); 
} 
private void form_MouseMove(object sender, EventArgs e) 
{ 

if (e.Button == System.Windows.Forms.MouseButtons.Left) 
{ 
Point mousePos = Control.MousePosition; 
mousePos.Offset(mouse_offset.X, mouse_offset.Y); 
this.Location = mousePos; 
} 
} 

报错错误 1 “System.EventArgs”并不包含“X”的定义 d:\test\vc\WindowsApplication6\WindowsApplication6\Form1.cs 25 41 WindowsApplication6 
错误 2 “System.EventArgs”并不包含“Y”的定义 d:\test\vc\WindowsApplication6\WindowsApplication6\Form1.cs 25 47 WindowsApplication6 
错误 3 “System.EventArgs”并不包含“Button”的定义 d:\test\vc\WindowsApplication6\WindowsApplication6\Form1.cs 30 19 WindowsApplication6 

我该怎么改?? e.X e.Y Button怎么定义 书上面没写定义啊

C# code

private   Point   mouse_offset;   private   void   form_MouseDown(object   sender,   [color=#FF0000]EventArgs   [/color]e)   {   mouse_offset   =   new   Point(-e.X,   -e.Y);   }   private   void   form_MouseMove(object   sender,   [color=#FF0000]MouseEventArgs [/color]e)   {   if   (e.Button   ==   System.Windows.Forms.MouseButtons.Left)   {   Point   mousePos   =   Control.MousePosition;   mousePos.Offset(mouse_offset.X,   mouse_offset.Y);   this.Location   =   mousePos;   }   }

MouseDonw 事件是有MouseEventArgs e 参数的。你检查一下，代码写错了。

若是无边框窗体的移动．
  bool beginMove=false;
  int currentXPosition = 0;
  int currentYPosition = 0;
  private void Fomr_MouseMove(object sender, MouseEventArgs e)
       {
           if (beginMove)
           {
               this.Left += MousePosition.X - currentXPosition;
               this.Top += MousePosition.Y - currentYPosition;
               currentXPosition = MousePosition.X;
               currentYPosition = MousePosition.Y;
           }
       }

       private void Fomr_MouseDown(object sender, MouseEventArgs e)
       {
           beginMove = true;
           currentXPosition = MousePosition.X;
           currentYPosition = MousePosition.Y;
       }

       private void Fomr_MouseUp(object sender, MouseEventArgs e)
       {
           beginMove = false;
       }

呃，又是移动无边框窗体的问题，把几个鼠标按键事件处理好就行了，唯一的技巧就是坐标的计算问题，实在简单的不行了，都懒得说了。
