When should the volatile keyword be used in C#?

Question

Can anyone provide a good explanation of the volatile keyword in C#? Which problems does it solve and which it doesn\'t? In which cases will it save me the use of locking?

Answer 1

From MSDN: The volatile modifier is usually used for a field that is accessed by multiple threads without using the lock statement to serialize access. Using the volatile modifier ensures that one thread retrieves the most up-to-date value written by another thread.
