In .NET, does the entire XML blob come into memory when I validate against a XSD?

Question

If I have a large (>500MB) XML file to validate, does an XmlReader bring the whole thing into memory to perform validation?

I looked at Validating an XML against referenced XSD in C# for validation procedure.

thanks, Mark

No, if you use XmlValidatingReader (or XmlReader with appropriate settings) it won't load the whole XML file. The method described in the question uses XmlDocument class which does load the whole file. The accepted answer doesn't load the entire file so you'll be fine using it.
