No it not possible Source: CoolInterview.com

System.GC.Collect() forces garbage collector to run. though it is not recommended to use as it may hamper the performance of your application.
You can use Dispose() method alternatively Source: CoolInterview.com

gc.Collect is only request to garbge collector for freeing the memory ocupied by an object.There is no guaranteed way to clear the memory occupied by a managed object. Source: CoolInterview.com

Actually the answer is no, as the GC decides on its own when to perform or not, even if you call .Collect() . Collect doesn't force any collection, it just indicates a signal and since GC is a deamon thread,and its priority is very low, it is likely that no collection will happen instantly.

The same goes for .Dispose for unmanaged resources, you mark the object and you never know the exact time that memory got freed. Source: CoolInterview.com

Yes, it is possible
We can call GC.Collect method to clear out memory explicitly.

GC is not an application level process. It is controlled by dotnet frame work. No other application can force or control GC. Application can mark the object is obselate and it is not required further more. GC works in a periodic time interval. It frees the memmories when it run Source: CoolInterview.com
