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.

Garbage collection ensures that a program does not exceed its memory quota or reach a point that it can no longer function. It also frees up developers from having to manually manage a program's memory, which, in turn, reduces the potential for memory-related bugs.
Garbage Collection is the process of reclaiming the runtime unused memory by destroying the unused objects. In languages like C and C++, the programmer is responsible for both the creation and destruction of objects.
One fundamental problem with garbage collection, though, is that it is difficult to estimate and manage the actual size of the working set in memory, because garbage collector can free your memory only delayedly. So, yes, when memory is restricted, garbage collection might not be a good choice.
As long as an object is being referenced, the JVM considers it alive. Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory.
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.
