Thread.MemoryBarrier Method

Synchronizes memory access as follows: The processor executing the current thread cannot reorder instructions in such a way that memory accesses prior to the call to MemoryBarrier execute after memory accesses that follow the call to MemoryBarrier.

Namespace:  System.Threading
Assembly:  mscorlib (in mscorlib.dll)

public static void MemoryBarrier()

MemoryBarrier is required only on multiprocessor systems with weak memory ordering (for example, a system employing multiple Intel Itanium processors).

For most purposes, the C# lock statement, the Visual Basic SyncLock statement, or the Monitor class provide easier ways to synchronize data.
