Confusion about the lock statement in C#

Question

This is from MSDN: The lock keyword ensures that one thread does not enter a critical section of code while another thread is in the critical sectio

Answer 1

No it means that another thread wont enter THE critical section protected by this lock statement.

The Critical section is only defined by the programmer, and in this case, you could replace it by : the section protected by a lock

So translation : The lock keyword ensures that one thread does not enter a section of code protected by a lock while another thread is in this section of code (protected by a lock )
