C # multi-thread Development 7: Use the Monitor class to synchronize multiple threads

In the article "Synchronize multiple threads with the lock statement", use the lock statement to synchronize multiple threads to access critical resources.

The code for using the lock statement is as follows.

Private static object o = new object (); lock (o) {if (account> = 1000) {Thread. sleep (10); // a small ATM account-= 1000; pocket + = 1000 ;}}

Use the ILDASM tool to view the IL code corresponding to the above Code:
