Alright, The following Code I ve have in production for over a year with no change. 它的工作进展良好。 在过去一个月里,一辆手提式机器报告说,Xml文件是完全空的。 他们甚至没有Xml头盔。 我不能突然重复这些档案,也不能提出这样做的办法。 我希望有人已经解决了类似的问题。

使用该代码的大部分机器已经使用了约一年,如果不是更多。 空档中的数据和清单是用的。 这些档案并不同时序列。 在方案退出之前,储蓄/序列。

My questions: is it possible for the code below to create an empty file? What else would cause them to be suddenly empty? Has anyone else had issues with XML-serializer in the past month? (This problem has only happened in the past month on builds that have been stable for 3+ months.)

如果你有问题或没有问题,请询问。 还有一些种类繁多的编号......这样,如果你能够想象,我可能具有类似的编号。
