It depends what your goals are. If it's a quick load for viewing then a SqlDataReader, potentially with multiple result sets, will do the trick. Otherwise hold all your data in a DataSet if you need to hold the data so you can update/write back to the database.

Entity Framework will provide you with a quick drag/drop approach to getting your data loaded.

you can use like below

using (SqlConnection sqlConn = new SqlConnection("MyConnString"))
    SqlCommand sqlCmd = new SqlCommand("SELECT * FROM MyTable", sqlConn);
    SqlDataReader sqlR = sqlCmd.ExecuteReader();

    while (sqlR.Read())


Open in new window
