如何在JavaFX8中锁定Microsoft Surface Pro的Windows10屏幕旋转

以下是不同场景下的可行实现，和你给出的Android端固定横向代码功能完全对应：

PowerShell 脚本方案（无需编译，直接运行） #

• 以管理员身份打开PowerShell，执行以下代码即可立即生效：

# 禁用系统自动旋转功能
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation" -Name "Enable" -Value 0 -Type DWord
# 设置显示方向为标准横向
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration" -Name "Rotation" -Value 0 -Type DWord
# 刷新显示配置使修改生效
RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True

• 如需解除锁定，将上述代码中Enable的值改为1后重新执行即可。

C# 代码方案（适合集成到自有应用中） #

• 核心调用Win32系统API实现，参考代码如下：

using System;
using System.Runtime.InteropServices;

public class OrientationLocker
{
    // 导入Win32显示设置API
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern int ChangeDisplaySettingsEx(string lpszDeviceName, ref DEVMODE lpDevMode, IntPtr hwnd, uint dwflags, IntPtr lParam);

    // 显示设置参数结构体定义
    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
    private struct DEVMODE
    {
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
        public string dmDeviceName;
        public short dmSpecVersion;
        public short dmDriverVersion;
        public short dmSize;
        public short dmDriverExtra;
        public int dmFields;
        public int dmPositionX;
        public int dmPositionY;
        public int dmDisplayOrientation; // 0=横向,1=纵向,2=横向翻转,3=纵向翻转
        public int dmDisplayFixedOutput;
        public short dmColor;
        public short dmDuplex;
        public short dmYResolution;
        public short dmTTOption;
        public short dmCollate;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
        public string dmFormName;
        public short dmLogPixels;
        public int dmBitsPerPel;
        public int dmPelsWidth;
        public int dmPelsHeight;
        public int dmDisplayFlags;
        public int dmDisplayFrequency;
        public int dmICMMethod;
        public int dmICMIntent;
        public int dmMediaType;
        public int dmDitherType;
        public int dmReserved1;
        public int dmReserved2;
        public int dmPanningWidth;
        public int dmPanningHeight;
    }

    /// <summary>
    /// 锁定屏幕为横向显示，禁用自动旋转
    /// </summary>
    public static void LockToLandscape()
    {
        // 设置显示方向为横向
        DEVMODE devMode = new DEVMODE();
        devMode.dmSize = (short)Marshal.SizeOf(typeof(DEVMODE));
        devMode.dmFields = 0x00000080; // 标识仅修改显示方向
        devMode.dmDisplayOrientation = 0;
        ChangeDisplaySettingsEx(null, ref devMode, IntPtr.Zero, 0, IntPtr.Zero);

        // 写入注册表禁用自动旋转
        Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation", "Enable", 0);
    }
}

• 应用内调用OrientationLocker.LockToLandscape()即可完成固定，注意运行应用时需要获取管理员权限，否则修改系统配置会失败。
