    <p>I'm reading a csv file and insert the information in a sql 2005 database.</p> <p>After about 250 object.save operations, it times out. here the code and the exact error message. this is not the first version of the code but it always give the same time out.</p> <p>This is not a big database, only 2 tables. Is there something I'm not doing ? Does it open and close a connection for every save operation. All input on that problem is welcome.</p> <pre><code>List&lt;shipment&gt; oLstShipments = new List&lt;shipment&gt;(); while (oReader.ReadNextRecord()) { int iIdShipment; if (int.TryParse(oReader[0], out iIdShipment)) { shipment oShipment = new shipment(); oShipment.idShipment = iIdShipment; oShipment.dateDelivered = oReader[1]; oShipment.inventoryGroup = oReader[2]; oShipment.companyId = oReader[3]; oShipment.shipTo = oReader[4]; oShipment.carrier = oReader[5]; oShipment.accountOwner = oReader[6]; oShipment.accountNumber = oReader[7]; oShipment.trackingNumber = oReader[8]; oLstShipments.Add(oShipment); } } oReader.Dispose(); oSR.Dispose(); foreach (shipment oShip in oLstShipments) { oShip.Save(); } </code></pre> <p>the error :</p> <pre><code>System.InvalidOperationException: Timeout expired.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
