how to create mysql db programmably

Question

Hi, I want to create a mysql table in a database in C#. this table should have unlimited fields where the user can add more information to it without having to overwrite the already existing information. I want to do this cos I will not know the amount of info the user will add in the table and this will give the user the ability to add as much info as and when it is available without the need to restructure the table. can I do that programmably and how?
