c# - Using and Garbage Collection

Hi just to clairfy if I have the following:

using (Object1) {
create Object2
}
// bookmark1

Will Object2 be destroyed at bookmark1 along with Object1? Object2 is of StringReader and Object1 is of MemoryStream.

See Question&Answers more detail:os

Neither object will be destroyed at the end of the block.

Object1 will be Disposed, a different concept; nothing will happen to Object2.

Both objects will be collected, and may be finalised, sometime later. Garbage collection is non-deterministic - you can't rely on when it will occur.

See IDisposable on MSDN for more.
