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.

Exporting a driver’s name to DosDevices

        &usDriverName, FILE_DEVICE_UNKNOWN, 
        FILE_DEVICE_SECURE_OPEN, FALSE, &DeviceObject);
