【中文标题】表格位置在屏幕右下角

【英文标题】：Form position on lower right corner of the screen

【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？

【参考方案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】：

或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。

【参考方案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);

【参考方案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); 

【参考方案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));

【参考方案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);
