Question

I’m dealing with pointer in C# using fixed{} phrases.

I placed my code inside the brackets of the fixed statement and want to know if the Garbage collection will handle the pointer freeing after the fixed statement

fixed{int * p=&x}
{
// i work with x.
}

if not how can I free it?

Answer 1

Your pointer points to a managed object (x) so there is nothing to worry about: the pointer does not need to be freed (or rather, it goes out of scope at the end of the fixed block) and the pointee x itself is managed by the GC.
