I need help converting my driver user interface code

I have a custom driver I have written.

Here is the source code to communicate to the driver in C:

#include <windows.h>
#include <stdio.h>

* Main Function Entry
int _cdecl main(void)
DWORD dwReturn;

hFile = CreateFile("\\\\.\\Example", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);

WriteFile(hFile, "Hello from user mode!", sizeof("Hello from user mode!"), &dwReturn, NULL);

return 0;

I want to be able to do this in .NET preferaly in VB.NET.

Does anyone know how to do the conversion?


The simplest is to use P/Invoke to OpenFile, WriteFile and CloseHandle.

You may find using the SerialPort class in the .net framework is easier. Check out the response to this question.
