C # Operation XML Preliminary (8) Chapter 4: General XML Processing Method (2) Previous, we provide a class to operate XML files, here is an example of an application, an XML written by boring time The message code for message data is as follows: use system;
Using system.io;
Using system.data;
Using system.diagnostics;
Using XMLbook.com.sem.tools; // This includes the class provided by the previous
Namespace XMLBOOK.COMPONENT

It is hoped that you can provide a little reference to you through the above example. The serial load for XML file is here. If you feel some help you. Please take me away. I am also a rookie just learned, many ideas, practices are very naive, don't smile. One XML message mentioned in this article, if anyone needs the original code, please contact me, I have no space can be uploaded, everyone can send me an email: Outrace@soueast-motor.com. Multi-exchange
