    <p>I'm using this library:</p> <p><a href="http://archive.msdn.microsoft.com/LinqEntityDataReader" rel="nofollow">Link to EntityDataReader</a></p> <p>to put some linq query results from a xml parse to a database with a sqlbulkcopy which us es a datareader to put the data directly without using datatables or such data structures.</p> <p>I am not able to implement it.</p> <p>This is the code I wrote so far without any success:</p> <pre><code>XDocument xdoc = XDocument.Parse(str_XmlToParse); //ORDINI IEnumerable&lt;XDocument&gt; xdod; var orders = from c in xdoc.Descendants("ordersdata").AsEnumerable().Descendants("order").AsEnumerable() select new { Client_ID = (string)c.Element("Client").Element("ID"), Doc_ID = (string)c.Element("ord_ID"), Doc_data = (DateTime)c.Element("ord_datetime"), }; IDataReader dr = orders.AsDataReader(); using (SqlConnection con = new SqlConnection(connectionString)) { con.Open(); using (SqlTransaction tran = con.BeginTransaction()) { var newOrders = from i in Enumerable.Range(0, totalToSend) select new Order { customer_name = "Customer " + i % 100, quantity = i % 9, order_id = i, order_entry_date = DateTime.Now }; SqlBulkCopy bc = new SqlBulkCopy(con, SqlBulkCopyOptions.CheckConstraints | SqlBulkCopyOptions.FireTriggers | SqlBulkCopyOptions.KeepNulls, tran); bc.BatchSize = 1000; bc.DestinationTableName = "order_queue"; bc.WriteToServer(newOrders.AsDataReader()); tran.Commit(); } con.Close(); </code></pre> <p>which is mostly a copy of what is in the examples of that library.</p> <p>I am not even understanding correctly what's going on with all their weird castings, but I need it to work. (believe me I tried to understand)</p> <p>I keep getting this error:</p> <blockquote> <p>Error 1 'System.Collections.Generic.IEnumerable AnonymousType#1>' does not contain a definition for 'AsDataReader' and no extension method 'AsDataReader' accepting a first argument of type 'System.Collections.Generic.IEnumerable AnonymousType#1>' could be found (are you missing a using directive or an assembly reference?)</p> </blockquote> <p>What is it? How do I fix it?</p> <p>Thanks</p>

    1. COPS. I assume this is a compiler error and not an exception. Correct?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
