I'm trying to find solution for more threads writing to a queue and a single thred is reading from it.
ConcurrentQueue it has
TryDequeue(T) that is thread safe but I'm not sure if
Enqueue(T) is thread safe too when writing to the queue from more threads.
Yes, the whole point of the concurrent collections is that they're thread-safe. It's fine to write to
ConcurrentQueue<T> from multiple threads.
From the documentation:
All public and protected members of
ConcurrentQueue<T>are thread-safe and may be used concurrently from multiple threads.
