What are various methods for thread synchronisation in c# [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

Apart from using lock(object) keyword, are there any fundamentally different or tricky or other useful in开发者_StackOverflow中文版 some situations ways to do syncronization ?

There are many classes in the Windows.Threading namespace.

Monitor and Mutex being two important classes for synchronization within the namespace (there are others). Lock is syntactic sugar for simple Monitor operations.

Interlocked provides some thread safe operations (Increment, Decrement and more).

I suggest going through the MSDN documentation for the namespace and different classed in it.

If you need to notify one thread of an event on a different thread, then ManualResetEvent and AutoResetEvent allow you to do so.

If you find that your code can handle simultaneous reads but need to synchronize writes, and your reading occurs much more frequently than your writes, then ReaderWriterLock (or now ReaderWriterLockSlim) will be of much help.

Mutex and Semaphore provide similar functionality to lock(), but can be used to synchronize across processes.

There are some others, but those are the three main others I typically use.

The question is very broad.
There are books about different synchronization technics and which to use in which scenario.
There are a lot of different ways to do synchronization.

Overview of Synchronization Primitives

Quite a few of new synchronization primitives where added in .NET 4. http://msdn.microsoft.com/en-us/library/dd460718.aspx
