【问题标题】:Form position on lower right corner of the screen表格位置在屏幕右下角
【发布时间】:2013-02-17 19:06:37
【问题描述】:

我正在使用 c# WinForm 开发一个 sman 通知应用程序。我想把主窗体放在屏幕工作区的右下角。 在多个屏幕的情况下,有一种方法可以找到最右边的屏幕来放置应用程序,或者至少记住最后使用的屏幕并将表单放在其右下角?

【解决方案1】:

我目前没有要检查的多个显示器,但应该是这样的

    public partial class LowerRightForm : Form
    {
        public LowerRightForm()
        {
            InitializeComponent();
        }

        protected override void OnLoad(EventArgs e)
        {
            PlaceLowerRight();
            base.OnLoad(e);
        }

        private void PlaceLowerRight()
        {
            //Determine "rightmost" screen
            Screen rightmost = Screen.AllScreens[0];
            foreach (Screen screen in Screen.AllScreens)
            {
                if (screen.WorkingArea.Right > rightmost.WorkingArea.Right)
                    rightmost = screen;
            }

            this.Left = rightmost.WorkingArea.Right - this.Width;
            this.Top = rightmost.WorkingArea.Bottom - this.Height;
        }
    }

【讨论】:

  • var rightmost = Screen.AllScreens.OrderBy (s => s.WorkingArea.Right).Last();
  • @GertArnold 我知道 MoreLINQ 的 MaxBy 效率最高,但如果我不得不冒险猜测 OrderByDescending.First 应该比 OrderBy.Last 更有效。
【解决方案2】:

覆盖表单Onload 并设置新位置:

protected override void OnLoad(EventArgs e)
{
    var screen = Screen.FromPoint(this.Location);
    this.Location = new Point(screen.WorkingArea.Right - this.Width, screen.WorkingArea.Bottom - this.Height);
    base.OnLoad(e);
}

【讨论】:

    【解决方案3】:
    //Get screen resolution
    Rectangle res = Screen.PrimaryScreen.Bounds; 
    
    // Calculate location (etc. 1366 Width - form size...)
    this.Location = new Point(res.Width - Size.Width, res.Height - Size.Height);

      【解决方案4】:

      以下代码应该可以工作:)

      var rec = Screen.PrimaryScreen.WorkingArea;
      int margain = 10;
      
      this.Location = new Point(rec.Width - (this.Width + margain), rec.Height - (this.Height + margain));

        【解决方案5】:
            int x = Screen.PrimaryScreen.WorkingArea.Right - this.Width;
            int y = Screen.PrimaryScreen.WorkingArea.Bottom - this.Height;
        
            // Add this for the real edge of the screen:
            x = 0; // for Left Border or Get the screen Dimension to set it on the Right
        
            this.Location = new Point(x, y);
