While studying several articles on the C# IDisposable pattern (e.g. Implementing IDisposable and the Dispose Pattern Properly[]), I was contemplating on the thread safe access of the Dispose() method.. If I have the need to program code that runs exactly once in a multi-threaded environment, there are several approaches.

WebNov 29, 2011 · C# Interlocked.Decrement ( ref int intNumber); This method decrement the value by 1 and assigns the updated value to itself as an atomic operation. C# Interlocked.Read ( ref int intNumber); It returns the value of variable specified in parameter. C# Interlocked.Exchange ( ref intNumber1, int intNumber2); WebPersonally, I prefer another strategy here, using reference-swapping - so reads can always read without ever checking / locking / etc. Writes make their change to a cloned copy, then use Interlocked.CompareExchange to swap the reference (re-applying their change if another thread mutated the reference in the interim).

WebAdd (Int32, Int32) Adds two 32-bit integers and replaces the first integer with the sum, as an atomic operation. Add (Int64, Int64) Adds two 64-bit integers and replaces the first integer with the sum, as an atomic operation. Add (UInt32, UInt32) Adds two 32-bit unsigned integers and replaces the first integer with the sum, as an atomic operation. WebSystem.Threading.Interlocked.CompareExchange operator provides atomic (thus thread-safe) C# implementation of the Compare-And-Swap operation. For example int i = 5; Interlocked.CompareExchange (ref i, 10, 5); After this command, the int i would have a value = 10. And also the compare and exchange happens atomically (single operation).
WebFeb 19, 2015 · 79. Yes, there is a good reason. The implementation of the Interlocked methods requires low-level support at the processor level. See this answer for example. That's an issue when you define a framework that's architecture agnostic. Implementing the low-lock techniques supported by the Interlocked class on data types that are a fraction … WebOct 11, 2012 · The difference with interlocked is that it uses a full memory barrier for its guarantees and handles non-atomic operations. Volatile may not use a full memory barrier (depends on platform, e.g. x86/x64 don't need a full memory barrier with volatile...) but only makes atomic operations "thread-safe".
