Another is this possible question: I have 4 webparts that read in a csv file, process it and create a IEnumberable that is used for graphing. Right now the webparts each read in and process the file. I was wondering if there is a way i could save off the result with a time stamp and then have the webparts use this (provided the timestamp doesn't indicate that it is old) stored version. I know a web service might be a way to solve this but that would be out of scope....so ideally looking for something simple where you could store it then pull it out/cast. Any ideas welcome :)

This is a straight forward caching question, so I'd use HttpRuntime.Cache in the first instance.

Here's a scenario from Tobias Zimmergren: http://zimmergren.net/technical/web-part-caching-a-simple-approach

  • Easier than what i had just come up with which was to create a connectable web part that would process the CSV and serve up the IEnumerable on request. Many thanks!
