调用 Keyboard.GetKeyStates 后 WinForms Window 大小更改（缩小）

Question

使用 .NET Framework 4.7.1

框架或表格 Window 调用后尺寸缩小 Keyboard.GetKeyStates 有什么理由吗？或者它是一个错误？我正在检查 ctrl 是否关闭或切换到其他 window .

 if (((int)Keyboard.GetKeyStates(Key.LeftCtrl) == 1 || (int)Keyboard.GetKeyStates(Key.LeftCtrl) == 3))
    {
        Console.WriteLine("pressed");
    }

如图所示：

as TnTinMn 评论它的 Dpi 感知问题，我找到了解决方案 here 还尝试从应用程序清单更改 dpi 选项，但没有用。

      static class Program
        {
            /// <summary>
            /// The main entry point for the application.
            /// </summary>
            [STAThread]
        //add this line 
[System.Runtime.InteropServices.DllImport("user32.dll")]
        private static extern bool SetProcessDPIAware();
        static void Main()
            {
        //add this line  
            if (Environment.OSVersion.Version.Major >= 6)
                SetProcessDPIAware();
    
            Application.EnableVisualStyles();
          Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
            }
    
    
    }
