GC in .net

[Guest]

What is the name of the Gc alogorithm used by .net?

What is the difference between Finalize() and Destructor()?

AFIK, the .NET GC is a generational garbage collector.

What is the difference between Finalize() and Destructor()?

Effectively nothing. In C#, all the ~YourClassName() does is override
finalize.

IIRC its known as "Mark and Sweep"

Do you mean a destructor in C# or as you currently know it in C++?

No, it is not a simple Mark and Sweep gc (which usually don't move objects
in memory), it is a generational gc that works by copying live objects to
avoid memory fragmentation (with special handling for large objects).

The *algorithm* it uses as to whether objects are alive or not is called Mark and Sweep. Yes it also performs generational compaction as well. And of course it doesn't always compact the heap either, it uses heuristics to assess the benefit of compacting compared with the overhead of all the memory copies.
