Critical regions - how to?

[Merrion]

I have a single function that may be called by more than one thread at once but I want it to be a critical region i.e. if one thread is already in it make the other thread wait for the region to be freed before entering.

 

Any ideas?

Aha -put System.Runtime.CompilerServices.MethodImplAttribute attribute on the function signature and specify Synchronised...sweet.

If you ever need to have a smaller critical section where you want to lock access to one object, you can use the VB.NET Synclock block.

A Mutex will also work quite well in many situations.
