C# 在单个/多个监视器上停靠WPF窗口

因此，在我的工具中，我编写了一个函数，将wpf窗口停靠在屏幕的右侧或左侧。它目前支持多个监视器，并在对接应用程序之前考虑应用程序所在的屏幕

然而，这个功能在单屏电脑上似乎不起作用，我也不完全清楚为什么会这样。当我点击“停靠右”按钮时，它似乎将窗口停靠在屏幕之外。不过，“左”停靠功能工作正常。有人知道为什么会这样吗？我有一台4k单显示器笔记本电脑

停靠左侧正常工作-单个和多个监视器

System.Windows.Point cursorPos = PointToScreen(Mouse.GetPosition(this));
            int X = Convert.ToInt32(cursorPos.X);
            int Y = Convert.ToInt32(cursorPos.Y);

            System.Drawing.Point pt = new System.Drawing.Point(X, Y);
            Screen screen = Screen.FromPoint(pt);

            //this.Left = screen.WorkingArea.Left;
            this.Left = screen.Bounds.Left;

System.Windows.Point cursorPos = PointToScreen(Mouse.GetPosition(this));
            int X = Convert.ToInt32(cursorPos.X);
            int Y = Convert.ToInt32(cursorPos.Y);

            System.Drawing.Point pt = new System.Drawing.Point(X, Y);
            Screen screen = Screen.FromPoint(pt);

            this.Left = screen.Bounds.Right - this.Width;

停靠右侧/断开-仅适用于多个监视器

System.Windows.Point cursorPos = PointToScreen(Mouse.GetPosition(this));
            int X = Convert.ToInt32(cursorPos.X);
            int Y = Convert.ToInt32(cursorPos.Y);

            System.Drawing.Point pt = new System.Drawing.Point(X, Y);
            Screen screen = Screen.FromPoint(pt);

            //this.Left = screen.WorkingArea.Left;
            this.Left = screen.Bounds.Left;

System.Windows.Point cursorPos = PointToScreen(Mouse.GetPosition(this));
            int X = Convert.ToInt32(cursorPos.X);
            int Y = Convert.ToInt32(cursorPos.Y);

            System.Drawing.Point pt = new System.Drawing.Point(X, Y);
            Screen screen = Screen.FromPoint(pt);

            this.Left = screen.Bounds.Right - this.Width;
