The I2C port expander have arrived yesterday. I've bought the MCP23017 I2C 16-port I/O expander, but first I've improved my LCD class to enable a string direct reading. As soon I have the port expander connected I will update with the final code and the fritzing schematic.
Netduino got i2c onboard doesn't it?
Still wondering about the i2c board...

Will it eliminate the need for pullup resistors ?Still wondering about the i2c board...

Your code makes me think about some code I wrote some 25 years ago ... using punch cards ... tedious work I had written : Computing is easy ! Which was not then LOL
You are correct. This is tedious work. I've already changed my LCD class to read a string directly to the LCD avoiding what
I have donne with the test() function. I will deliver the code after connecting to the I2C expander.

Netduino has the I2C ability, yes. After connecting to the expander I will give some details.

Do you mean the I2C pullup resistors? Thouse are always needed.
