A lightweight Mono/.Net/C# Wrapper for interacting with i2c devices on linux.
be sure that your user/process has access to the relevant device file(s) either through sudo or permissions
hint, if you're running through monodevelop, it probably doesn't
//open i2c bus 1, aka /dev/i2c-1
using (var i2cBus = new I2CBus(0x01))
{
//create a device at address 0x3c
var i2cDevice = new I2CDevice(i2cBus, 0x3c);
var bytes = new byte[2];
//read 2 bytes starting at register 0x00
i2cDevice.ReadBytes(0x00, 2, bytes);
//do someting useful with the bytes
}//note that disposing the bus closes the file
