Interlocked.Increment Method (Int32%)
Updated: February 2009
Increments a specified variable and stores the result, as an atomic operation.
Assembly: mscorlib (in mscorlib.dll)
The following code example shows a thread-safe way to increment and decrement an integer value. SafeInstanceCount will always be zero. However, UnsafeInstanceCount will not necessarily be zero because a race condition occurs between incrementing and decrementing the count. This effect is especially marked on a multiprocessor computer.
