        SqlConnection conn = new SqlConnection();

        conn.ConnectionString = @"Data Source=(LocalDB)     \v11.0;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True";

        try

        {

            conn.Open();

            return (conn.State == ConnectionState.Open);

        }

        catch (SqlException ex)

        {
