问题 From the MSDN documentation for the FileInfo.Name property, I see that the data for the property is cached the first time it is called and will only be updated subsequently by using the Refresh method. I've the following questions which I can't find or aren't too clear in the documentation: Is the data for all properties cached at the same time?
