Accessing Device Drivers from C#
By David Union, April 01, 2002
Device Drivers are written largely in C or C++. No explicit support for Device Driver communication is included in the current .NET framework. David implements support with C# and discusses how to access Win32 APIs using the Platform Invocation Services and how to make that reusable from within the .NET framework with Overloading.

[DllImport("Kernel32.dll", CharSet=CharSet.Auto, SetLastError=true)]
public static extern int CreateFile(String lpFileName,
int dwDesiredAccess, int dwShareMode,
IntPtr lpSecurityAttributes, int dwCreationDisposition,
int dwFlagsAndAttributes, int hTemplateFile);
[DllImport("Kernel32.dll", CharSet=CharSet.Auto, SetLastError=true)]
public static extern int CreateFile(String lpFileName,
int dwDesiredAccess, int dwShareMode,
ref SECURITY_ATTRIBUTES lpSecurityAttributes, int dwCreationDisposition,
int dwFlagsAndAttributes, int hTemplateFile);
