This method loads data from SQL select (with parameters) to the list of rows, where each row is the dictionary of columns (the key is the column name).

private static List> LoadData(string sqlSelect, params object[] sqlParameters)
{
    var table = new List>();
    using (var ctx = new DbEntities())
    {
        ctx.Database.Connection.Open();
        using (var cmd = ctx.Database.Connection.CreateCommand())
        {
            cmd.CommandText = sqlSelect;
            foreach (var param in sqlParameters)
                cmd.Parameters.Add(param);
            using (var reader = cmd.ExecuteReader())
            {
                while (reader.Read())
                {
                    var row = new Dictionary();
                    for (int i = 0; i < reader.FieldCount; i++)
                        row[reader.GetName(i)] = reader[i];
                    table.Add(row);
                }
            }
        }
    }
    return table;
}
