Adding 90000 XElement to XDocument
- by Jon
I have a Dictionary<int, MyClass>
It contains 100,000 items
10,000 items value is populated whilst 90,000 are null.
I have this code:
var nullitems = MyInfoCollection.Where(x => x.Value == null).ToList();
nullitems.ForEach(x => LogMissedSequenceError(x.Key + 1));
private void LogMissedSequenceError(long SequenceNumber)
{
DateTime recordTime = DateTime.Now;
var errors = MyXDocument.Descendants("ERRORS").FirstOrDefault();
if (errors != null)
{
errors.Add(
new XElement("ERROR",
new XElement("DATETIME", DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss:fff")),
new XElement("DETAIL", "No information was read for expected sequence number " + SequenceNumber),
new XAttribute("TYPE", "MISSED"),
new XElement("PAGEID", SequenceNumber)
)
);
}
}
This seems to take about 2 minutes to complete. I can't seem to find where the bottleneck might be or if this timing sounds about right?
Can anyone see anything to why its taking so long?
