如何在最大分辨率为 1366x768 的计算机上设计 1920 x 1080 像素的 WinForm？

Question

我正在笔记本上开发一个 winforms 应用程序（屏幕分辨率：1366x768）。该应用程序的终端设备是windows surface（屏幕分辨率1920x1080）。现在我想让我的表单和用户控件更大，以便它们可以在表面上全屏显示。我已经在我的主窗体上使用此代码完成了此操作：

        Left = Top = 0;
        Width = Screen.PrimaryScreen.WorkingArea.Width;
        Height = Screen.PrimaryScreen.WorkingArea.Height;

但在我的 UserControls 中，我需要将按钮文本框等放在正确的位置。否则，应用程序的大部分区域都未使用。所以我需要使用户控件和表单的大小更大，但我的笔记本的屏幕分辨率太小，所以它不允许超过 1366x768 像素的数字。我该如何设计应用程序以适应表面的屏幕分辨率？

以下代码是从 VB.Net answer that I posted several years ago on CodeProject 直接翻译（通过工具），所以从当前 C# 时尚趋势的角度来看，它会看起来很奇怪。但是它在基于 Windows 的 PC 上可以正常工作。

将此Form 定义添加到您的项目中。执行构建。然后，您可以使用 Inherited Form 项模板添加从该表单派生的表单。通过 propertygrid，将 MaxDesignWidth 和 MaxDesignHeight 属性设置为与您的目标分辨率匹配的值。

using System;
using System.Windows.Forms;
using System.ComponentModel;
using System.Runtime.InteropServices;

    [Category("Design"), DisplayName("MaxDesignWidth")]
    public Int32 aaa_MaxDesignWidth //Prefix aaa_ is to force Designer code placement before ClientSize setting

        get // avoids need to write customer serializer code
