Question

I am using TvdbLib in a program. This library can use a cache for loading TV series quicker. To further improve the speed of the program, I do all my loading of TV series on separate threads. When two threads run simultaneously and try to read/write from the cache simultaneously, I will get the following error:

The process cannot access the file
‘C:\BinaryCache\79349\series_79349.ser’ because it is being used by
another process.

Does anyone know how to avoid this and still have the program running smoothly?

CacheProvider is not built for being used in multi-threaded scenarios… either use it in one thread only or lock on every access via a shared object or supply every thread with its own CacheProvider and its own distinct _root directory (in the constructor).
