what is the relationship between Finalize method and destructor?

class Program
{
    static void Main(string[] args)
    {
    }
    ~Program()
     {
        // clean resources
     }

GC will maintain a separate queue for items that need finalization. So you should implement the Dispose() pattern and clean all your resources. Also call GC.SuppressFinalize() from dispose which will suppress the finalization.

Which tool are you using to check IL code?

George_George wrote:

GC may have some smarter ways to treat all the to be finalized resources altogether?

C# has integer types, int, int32, int64 and long. In my understanding, int32 is always 32-bit, int64 and long are always 64-bit.

How about int? Is it 32-bit or 64-bit or depends on how we build application (build as 32-bit? build as 64-bit or any CPU?)
