how to use c# to get start the rapid ?

recently i have a project to write the Chinese Characters by using the ABB 1410.
what i have done:
i have finished the rapid codes and i've checked out at the real robot. it proof that is correct.
issues:

2)how can I conmunicate bewteen IRC5 and PC by using the c# windows application?
3)how to get start the RAPID by clicking the button on windows app?
