Find columns in select query

Hello,

I don't know if this is the right place to ask this question but I thought it would be the best bet.

I want to be able to detect the column names in any given select queries, I though using a regular expression would be the most robust way of achieving this using c#.

I need to be able to handle:

Select * from table

select orders.*, production.* from table

Select id,name,surname from table

select distinct id,name,surname from table

select top(100) id,name,surname from table

I need to return with id,name,surname or * or orders.*

Any suggestions would be welcome,
