access-violation

I'm having an issue opening files that have recently been closed by the .Net framework. Basically, what happens is the following:
-Read in an XML file using DataSet.ReadXml()
-Make some changes to the data
-Write out the XML file using DataSet.WriteXml()
-Copy the XML file to a new location using File.Copy
-FTP the file using a custom control

This sequence can intermittently fail either after the WriteXML or the File.Copy with a file in use exception.
I'm guessing it could be the Windows write cache not flushing right away. Can anyone confirm that this could be causing my issue? Any solutions to suggest?

Thanks,
Dan

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
