C# MySQL Database work

I've got a half finished project written in C# and most of the hard work is done. It is related to an online game. At the moment the program retrieves player data from the server and writes it to a .txt file. Instead of it doing this, I need it to place all of the data in a MySQL database and create special flags per user. These flags will be used to update character data at different rates (eg: banned players aren't refreshed, idle players are refreshed once a week, active players are refreshed daily, etc) For someone who knows what they are doing, it shouldn't take much time at all.
