C # "Thread" Interlocked lightweight lock

What do you mean, it's lightweight? Because it synchronizes only the shaping data (that is, the int type, the long line) .

Use the following table specifically:

Interlocked.Increment (ref value)	Value plus one (atomic operation)
Interlocked.decrement (ref value)	Value minus one (atomic operation)
Interlocked.exchange (ref value1, value2)	Exchange: Assigns the value 2 to the value 1; Returns the new value
Interlocked.compareexchange (ref value1, value2, Value3)	To achieve the comparison and exchange of two functions: the value 1 and the value 3 comparison, if the same, the value of 2 to the value of 1, not the same does not do anything; return the original value (more for judging the condition) (used in example 3)
