BCL mscorlib [00 00 00 00 00 00 00 00 04 00 00 00 00 00 00 00 ] 1.0.5000.0 2.0.0.0 4.0.0.0 All public static members of this type are safe for multithreaded operations. No instance members are guaranteed to be thread safe. System.Object

The class provides atomic operations for variables that are shared by multiple threads.

The 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.

The method and its counterpart, ,

increment or decrement a variable and store the resulting value, as an atomic operation.

The method atomically exchanges the values of the specified variables. The 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.
