Basically, I would like a brief explanation of how I can access a SQL database in C# code. I gather that a connection and a command is required, but what's going on?

Based on a simple test I ran, I don't think it's possible to put an inline <style> tag into an ASP.NET server control. The style did not end up rendering to the output HTML. Even if it was possible, I'm sure it is bad practice to do this. Is it possible to do this? I can see it being useful for quick prototypes that just have 1 or 2 ...
