在C#中定义DEVMODE

DEVMODE数据结构中包含了有关设备初始化和打印机环境的信息。在C#中定义DEVMODE结构：

       [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

        public 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 short dmOrientation;

            public short dmPaperSize;

            public short dmPaperLength;

            public short dmPaperWidth;

            public short dmScale;

            public short dmCopies;

            public short dmDefaultSource;

            public short dmPrintQuality;

            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;

        }
