You will either need a separate SqlConnection instance (ie don't pass in the connection to that method, create a new one) or you'll need to enable Multiple Active Result Sets.
Even when you get it to work, I'm guessing you'll run into a transaction dead lock since you are reading what you are attempting to write. If I were to make a recommendation, either pull all the data from the first reader into memory (like a list) or do it in batches and pull each batch into memory before running the update.
