Local variables and stack

Question

What will happen in the following code snippet:

while (!Done)
{
     Data data = source.GetData();
     sink.ProcessData(data);
}

Is a new link datapushed onto the stack at each iteration of the loop (thus preventing garbage collection of object references data), or is this link reused at each iteration?

Answer 1

The variable is "reused" as you say. Stack / local variables are just what is local to the method and NOT a scope. The area in which your variable is located dataonly keeps it from being visible outside this scope and, conversely, does NOT define a different stack slot.
