Detailed analysis of sample code for generating xml documents based on xsd

Currently, many xml tool software can write xml documents according to the xsd file book ,. net does not implement this method. if I have written several methods for browsing, verifying, and creating xml, many xml tool software can write xml documents according to the xsd file book ,. net does not implement this method. for example, I have written several methods for browsing, verifying, and creating xml.
The code is as follows:
