/// 这个示例演示如何把office文件编码为xml文件以及如何把生成的xml文件转换成office文件
/// 把文件转换成xml格式,然后就可以用web服务,.net remoting,winsock等传送了(其中后两者可以不转换也可以传送)
/// xml解决了在多层架构中数据传输的问题,比如说在客户端可以用web服务获取服务器端的office文件,修改后再回传给服务器
/// 只要把文件转换成xml格式,便有好多方案可以使用了,而xml具有平台无关性,你可以在服务端用.net用发布web服务,然后客户端用
/// java写一段applit小程序来处理发送过来的文件,当然我举的例子几乎没有任何显示意义,它却给了我们不少的启示.
/// 另外如果你的解决方案是基于多平台的,那么他们之间的交互最好不要用远程应用程序接口调用(rpc),应该尽量用基于文档的交互,
/// 比如说.net下的msmq,j2ee的jmq.
///
/// 示例中设计到好多的类,我并没有在所有的地方做过多注释,有不明白的地方请参阅msdn,这是偶第一个windows程序,有不对的地方
/// 欢迎各位指导
