Well you left out a ton of information which is needed to give you an accurate answer. Like what database engine you are using, and which type of server they are on, local or remote, and how you are connecting to said server already....

Well, since you only want to get a date object from the database, I would use SqlCommand.ExecuteScalar Method (System.Data.SqlClient) with a select statement. I assume you know how to write them....
