Abstract: This article introduces that the C # monitor class can lock an object. A thread can operate on this object only when this lock is obtained. The object lock mechanism ensures that only one thread can access this object at a time point that may cause confusion. When multiple threads share an objectCodeFor a similar problem, the lock keyword should not be used. here we need to use a class monitor

Said to be incompatible, the actual fault is not a true sense of incompatibility, only from the symptoms of failure and language expression on the use of the word "incompatible" is more appropriate. This failure is not uncommon, with the computer more and more time to use, monitors and mainframe components are also slowly aging, capacitance capacity in the slowly become less, resistance will have some changes, then there may be some inexplicable fault, to our maintenance bring great trouble.Here
