None of them. If it was possible to free memory by garbage collection, the underlying system was call it automatically...
Find the reason for your OutOfMemory exception and resolve that problem...

Unless your application is written extremely badly, it should not be necessary to even invoke the GC directly: instead, check that you are Disposing of all objects which support IDisposable, as it is unlikely yo be actual memory that is causing your problem: "Out of memory" is a generic error which means that some scarce resource is exhausted, it doesn't have to be heap space.

They are both different things. The SuppressFinalize(this) call will prevent the garbage collector from calling the the Finalize method for the specified object, also see the documentation[^] on that.

The WaitForPendingFinalizers[^] will block the calling thread until all finalizers have been called.

However, I do advise you to tread carefully when calling this. In some cases this might be necessary, but I would first look into why you're getting an OutOfMemoryException before calling the garbage collector.
