Is it possible to stop .NET garbage collection?

Question

Is it possible for a programmer to programmatically start/stop the garbage collection in C# programming language? For example, for performance optimization and so on.

Answer 1

Since .NET 4.6 it's possible, there are methods in the GCclass:

GC.TryStartNoGCRegion(...) and GC.EndNoGCRegion().

Answer 2

Not really. You can give the GC hints via methods like GC.AddMemoryPressure or GC.RemoveMemoryPressure but not stop it outright.

Besides, garbage collection is not that intensive of a process. Programmers very rarely ever worry about it.
