I have a method which is called frequently from multiple threads. It involves writing to disk using await FileIO.WriteTextAsync
. This works fine when it is called from a single thread, but once I start doing this in multiple threads, I get this error:
The process cannot access the file because it is being used by another process.
I know what the error means, but I'm not sure how to work around it. Normally, I would create a lock(object)
statement, to ensure that the file is being accessed by only one thread at a time. However, this is an asynchronous method and as such I can't use the await
operator in the body of the lock(object)
statement.
Please advise on how to handle this scenario.
