C# - Best Approach To Write Huge Xml Data To File?

Apr 20, 2010

I'm currently exporting a database table with huge data (100000+ records) into an xml file using XmlTextWriter class and I'm writing directly to a file on the physical drive.

_XmlTextWriterObject = new XmlTextWriter(_xmlFilePath, null);

While my code runs ok, my question is that is it the best approach? Or should I write the whole xml in memory stream first and then write the xml document in physical file from memory stream? And what are the effects on memory/ performance in both cases?

EDIT

I will indeed be using XmlTextWriter but I meant to say whether to pass a physical file path string to the XmlTextWriter constructor (or, as John suggested, to the XmlTextWriter.Create() method) or use stream based api. My current code looks like the following:

Forms Data Controls ::displaying Huge Data?

Apr 20, 2010

We have our web-based car tracking (gps) software developed in asp.net. We receive positional information every 30 seconds. Overall we get millions of records everyday. We have a historical view which displays the position where the car was throughout the day (24hr period) - this page takes a long time to load. We tried indexing the db, de-normalizing it and also re-wrting the queries - but still not a great improvement. Is there any other best practise that we should follow to load huge loads of data into a webpage (there should be no pagination)? Can we somehow bring it to the clientside using AJAX and try loading it when the button is clicked?
