How would you simply Monitor.TryEnter

Question

This is even worse than the ReaderWriterLock in terms of noise.

 If Threading.Monitor.TryEnter(syncRoot) Then
  Try
   'do something
  Finally
   Threading.Monitor.Exit(syncRoot)
  End Try
 Else
  'do something else
 End If

Both C# and VB solutions are welcome.

Answer 1

This is very similar to your last post, and I would expect a similar answer. The only significant difference is that you might return "null" from your method if the timeout fails - then the "Dispose()" is not called, and you can easily check the value:

using(var token = GetLock(syncLock, timeout)) {
  if(token != null) { ... }
}

The only real glitch is that you don't necessarily want to add an extension method to "object" (or even "T where T : class")...

Jon Skeet has looked at this in the past - worth a look.

Answer 2

Use a delegate?

E.g.

public bool TryEnter(object lockObject, Action work) 
{
    if (Monitor.TryEnter(lockObject)) 
    {
       try 
       {
          work();
       }
       finally 
       {
           Monitor.Exit(lockObject);
       }        
       return true;
     }

     return false;
}
