Lock free constructs in .net

Question

I am new to .net and would like to know whether .net has the java equivalent of AtomicInteger, ConcurrentLinkedQueue, etc?

I did a bit of search and couldnt come up with anything.

The lock free algorithms need some sort of a CAS instruction, which is provided through the undocumented Unsafe class in Java, does .net have anything equivalent?

Answer 1

In .NET there is the Interlocked class, with static methods Interlocked.Increment() and Interlocked.Decrement().

See http://msdn.microsoft.com/en-us/library/system.threading.interlocked.aspx.

You will also find other atomic och synchronization constructs in the System.Threading namespace.
