Answer 5

The garbage collector checks every now and then if there are objects that are now longer is use and disposes those objects.

In c# this goes automatically. You do not need to worry about releasing the memory of a object. The c# garbage collector does it for you.

But you can help the garbage collector a bit. Especially when your objects connect to source outside of the c# enviroment like files and databases. By using the using statement.

using
{
}
This tells the garbage collector that the object at "}" the object is out of scope and can be discarded.
