从 user32.dll EnumDisplayDevices 取回坏字符串

Question

我正在尝试从 user32 获取我的监视器的名称。到目前为止，我所得到的都是汉字。我不确定为什么，任何帮助将不胜感激。    public static SafeNativeMethods.DISPLAY_DEVICE GetDevices()    {        SafeNativeMethods.DISPLAY_DEVICE d = new SafeNativeMethods.DISPLAY_DEVICE();        d.Initialize();        if (SafeNativeMethods.EnumDisplayDevices(null, 1, ref d, 0))            return d;        else            throw new InvalidOperationException(GetLastError());    }public static class SafeNativeMethods{    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]    public struct DISPLAY_DEVICE    {        [MarshalAs(UnmanagedType.U4)]        public int cb;        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]        public string DeviceName;        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]        public string DeviceString;        [MarshalAs(UnmanagedType.U4)]        public int StateFlags;        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]        public string DeviceID;        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]        public string DeviceKey;        public void Initialize()        {            this.DeviceName = new string(new char[32]);            this.DeviceString = new string(new char[128]);            this.DeviceID = new string(new char[128]);            this.DeviceKey = new string(new char[128]);            this.cb = (ushort)Marshal.SizeOf(this);        }    }        [DllImport("User32.dll", SetLastError = true, BestFitMapping = false, ThrowOnUnmappableChar = true)]        public static extern Boolean EnumDisplayDevices(            [param: MarshalAs(UnmanagedType.LPTStr)]            String lpDevice,            [param: MarshalAs(UnmanagedType.U4)]            Int32 iDevNum,            [In, Out]            ref DISPLAY_DEVICE lpDisplayDevice,            [param: MarshalAs(UnmanagedType.U4)]            Int32 iHaveNoIdea        );}此代码返回设备名称屜尮䥄偓䅌㉙任何人都可以解释为什么以及如何从中获取正常名称吗？

Answer 1

“中文字符”通常意味着您试图将 ASCII 字符串解释为 Unicode (UTF-16)。

尝试在您的声明中添加一个CharSet属性。EnumDisplayDevices
