Question

I want to make an xml file but add certain elements selectively. I would like to build those elements in memory and be able to choose whether to be written to the xml file or not. Is this possible? I’m using C# WinForms. I already looked at XmlDocument which will allow me to build an entire xml in memory but I don’t want this since it’s not good for large data and also takes too much memory.

If you have a stream, named say stream, then you can create an XmlWriter by

XmlWriter.Create(stream);

Then, you can create your elements, (which are type XmlElement), and call the WriteTo method on each element you want to add, passing as an argument the XmlWriter created by XmlWriter.Create.
