C#中，双屏/两屏/三屏/多屏跳转判断

if (Screen.AllScreens.Length == 2)
{
//此显示器是否为主屏
if (Screen.AllScreens[0].Primary)
{
this.Top = Screen.AllScreens[1].Bounds.Y;
this.Left = Screen.AllScreens[1].Bounds.X;
}
else
{
this.Top = Screen.AllScreens[0].Bounds.Y;
this.Left = Screen.AllScreens[0].Bounds.X;
}
}
else if (Screen.AllScreens.Length == 3)
{
this.Top = Screen.AllScreens[2].Bounds.Y;
this.Left = Screen.AllScreens[2].Bounds.X;
}
