Question

Here is an example of an exception happening inside a lock, with a try-catch block.

int zero = 0; int j = 10;  lock (sharedResource.SyncRoot) {     try     {         j = j / zero;     }     catch (DivideByZeroException e)     {         // exception caught but lock not released     } } 

How do I safely release this lock in the catch?

Answer 1

Won’t it be released automatically?

From the MSDN lock means

System.Threading.Monitor.Enter(x); try {    ... } finally {    System.Threading.Monitor.Exit(x); } 

So you don’t have to bother.
