    1. COGarbage collection? Nothing is allocated on the heap in either case here. Passing a reference to an already allocated object doesn't involve any GC work. In any case, these are parameters, they are on the stack, so the GC isn't involved in allocating/deallocating those items. Taking up a few extra bytes on the stack is pretty tiny, and will have no runtime speed implications.

    2. COAs I said, any difference will be negligible. It's not necessarily true at all that passing a reference to a heap object doesn't involve GC work. The GC has to track/count references. Nor is it true that a few extra bytes on the stack has no runtime speed implications - try passing a large data structure on the stack to highly recursive method. The data structure size not only makes a speed difference but could take you over the stack allocation limit.

    3. CONo, the GC does *not* track/count references; that's not how it works. Perhaps you should spend a bit of time reading up on the .NET GC. As for stack allocations, "allocating" more space on the stack is simply incrementing a pointer (the stack pointer). Incrementing it by 4 words is no more or less expensive than incrementing it by 2 words. Likewise de-allocating the memory from the stack has no more or less cost, decrimenting the stack pointer by 4 words has the same cost as decrimenting it by 2 words. The time would only differ in what it takes to copy *useful* data, not in allocating.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
