UWP中不存在数据读取器，数据集，sqlconnection等Ado.Net之类的东西。  您可以将实体框架用于SQLite数据库。  如果要连接到Sql Server，则需要通过Web服务进行。

On a standard cs winforms/asp.net application I can use System.Data.SqlConnection to connect to my server something like:

            List<Video> rv = new List<Video>();
            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                connection.Open();

                SqlCommand command = new SqlCommand(String.Format("SELECT * FROM Video"),
                                                    connection);
                SqlDataReader reader = command.ExecuteReader();
                

                while (reader.Read())
                {
                    IDataReader record = reader;
                    string name = String.Format("{0}", record[0]).Trim();
                    string id = String.Format("{0}", record[1]).Trim();
                    string src = String.Format("{0}", record[2]).Trim();
                    string metaData = String.Format("{0}", record[3]).Trim();
                    string discription = String.Format("{0}", record[4]).Trim();
                    string datePosted = String.Format("{0}", record[5]).Trim();
                    string status = String.Format("{0}", record[6]).Trim();
                    string privateHiden = String.Format("{0}", record[7]).Trim();
                    string views = String.Format("{0}", record[8]).Trim();



                    Video video = new Video(name, id, datePosted, metaData, discription, src, status, privateHiden, views);
                    rv.Add(video);

                }
                reader.Close();

To return a list.

Is there any way to use this in universal windows?

None of the Ado.Net stuff like data readers, data set, sqlconnection, etc exist in UWP.  You can use entity framework to a SQLite data base.  If you want to connect to a Sql Server you need to do it through a web service.
