c# winform窗体边框风格的设计

1.首先，窗体的FormBorderStyle设置成None,不要控制边框。

2.然后，TransparencyKey和BackColor颜色设置成相同的,这样,窗体就透明了。

3.最后，窗体的拖动

private void pictureBox1_MouseMove(object sender, MouseEventArgs e)

{

     if (e.Button == MouseButtons.Left)

     {

          this.Left += e.Location.X - this.oldX;

          //新的鼠标位置                

       this.Top += e.Location.Y - this.oldY;

      }

}

  

private int oldX = 0;        

private int oldY = 0;        

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)        

{            

     if (e.Button == MouseButtons.Left)            

     {                

          this.oldX = e.Location.X;        

          //鼠标原来位置                

       this.oldY = e.Location.Y;            

      }        

}
