#include is much clearer than if statement version.
, in the process of running a program, concurrency is infrequent, so optimists present their handling patterns: When I execute a method, allow other visitors to intervene in the method. ( optimists often think that a bad thing doesn't happen to them )So in the C # language, what are those pessimists?in C #, such as: Lock, Monitor, interlocked and other methods of locking data, belong to pessimistic concurrency processing category! Once the data is locked, other visitors are not authorized to acc
