/** // <Summary>
/// This example shows how to encode an Office file as an xml file and convert the generated xml file to an Office file.
/// Convert the file to xml format, and then use the web service,. NET Remoting, WinSock, and so on for transmission (the latter two can be transmitted without conversion)
/// Xml solves the problem of data transmission in a multi-layer architecture. For example, you can use the Web service on the client to obtain the office file on the server, modify the file, and then send it back to the server.
/// As long as the file is converted into xml format, there are many solutions available, and xml is platform-independent, and you can use it on the server.. net is used to publish web Services, and then the client uses
/// Write an applit Applet in Java to process the sent files. Of course, the example I gave has almost no explicit meaning, but it has given us a lot of inspiration.
/// In addition, if your solution is based on multiple platforms, it is best not to use remote application interface Call (RPC) for interaction between them. Try to use document-based interaction,
/// For example, MSMQ under. net and JMQ of j2ee.
///
/// Many classes have been designed in the example. I have not made too many comments in all the places. For more information, see MSDN. This is my first windows program, something wrong
/// Welcome to your guidance
