C#中，双屏/两屏/三屏/多屏跳转判断

之前伤脑筋写过一次在Web中，JS,ActiveXObject去读取显示器数量、分辨率去判断单双屏跳转。

那么在客户端中，用C#去读取硬件信息，更方便更容易！

思路参考代码：

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