性能计数器和线程

Question

I am creating some custom performance counters. I will be creating tasks on a thread pool and incrementing/decrementing the counters from within multiple worker threads.

Do I need to give each thread a new counter object? Is it safe to share a performance counter object cross-thread (for increment/decrement)

Answer 1

The PerformanceCounter class already uses a threadsafe wrapper, an internal class named SharedPerformanceCounter. It uses Interlocked.Increment() to increment a counter value for example.

There's no need to lock yourself.
