Use of Interlocked class in vb. net?
The Interlocked methods protect against errors that can occur when the scheduler switches contexts while a thread is updating a variable that can be accessed by other threads. The members of this class do not throw exceptions.
[Note: The System.Threading.Interlocked.Increment(System.Int32@) method and its counterpart, System.Threading.Interlocked.Decrement(System.Int32@), increment or decrement a variable and store the resulting value, as an atomic operation.
The System.Threading.Interlocked.Exchange(System.Int32@,System.Int32) method atomically exchanges the values of the specified variables. The System.Threading.Interlocked.CompareExchange(System.Int32@,System.Int32,System.Int32) method provides an atomic operation that compares two values and stores a third value in one of the variables, based on the outcome of the comparison.
