Working with IOExceptions using XmlWriter.Create () and XmlDocument.Load () in separate threads

Question

I inherited some code that includes a scheduled task that writes data (received from an external source) into XML files and a website that reads the specified XML files to get information for the visitor.

There is no synchronization, and, of course, sometimes the scheduling task cannot write a file because it is currently open for reading.

The heart of the write code is:

XmlWriter writer = XmlWriter.Create(fileName);
try
{
  xmldata.WriteTo(writer);
}
finally
{
  writer.Close();
}

And the heart of the reader code:

XmlDocument theDocument = new XmlDocument();
theDocument.Load(filename);

(exception handled at both ends)
