C#'s lock() in Managed C++

Question

Does managed C++ have an equivalent to C#'s lock() and VB's SyncLock? If so, how do I use it?

Answer 1

C++/CLI does have a lock class. All you need to do is declare a lock variable using stack-based semantics, and it will safely exit the monitor when its destructor is called, e.g.:

#include <msclr\lock.h> {         msclr::lock l(m_lock);      // Do work  } //destructor of lock is called (exits monitor).   

m_lock declaration depends on whether you are synchronising access to an instance or static member.

To protect instance members, use this:

Object^ m_lock = gcnew Object(); // Each class instance has a private lock -                                   // protects instance members. 

To protect static members, use this:

static Object^ m_lock = gcnew Object(); // Type has a private lock -                                         // protects static members.
