C # 's Lock

The lock keyword marks a statement block as a critical section by obtaining a mutex for a given object, executing the statement, and then releasing the lock.

classProgram {Static voidMain (string[] args) {Thread T=NewThread (lockobject.monitorincrement); Thread T1=NewThread (NewThreadStart (lockobject.lockincrement));                       T.start (); T1.                  Start (); }    }     Public classLockObject {/// <summary>        ///multi-threaded shared data/// </summary>         Private Static intCounter =0; /// <summary>        ///synchronizing objects, recommending this notation///you should avoid locking the public type, or the instance will go beyond the control of your code///details such as: Lock (This), Lock (typeof (MyType)) and lock ("MyLock")/// </summary>         Private ReadOnly Static ObjectSynisynchronize =New Object();  Public Static voidmonitorincrement () {///Monitor.Enter and Monitor.Exit are equivalent to lockMonitor.Enter (synisynchronize); Thread.Sleep ( +); Counter++; Console.WriteLine ("monitorincrement counter={0}", counter);        Monitor.Exit (synisynchronize); }         Public Static voidlockincrement () {///Lock calls Monitor.Enter at the beginning///call Monitor.Exit at the end.             Lock(synisynchronize) {counter++; Console.WriteLine ("lockincrement counter={0}", counter); }        }    }

The results of the operation are as follows:
