What is the most terse syntax to combine a check for some preconditions with a switch statement? Can I combine an if/else and switch statement?
if (!IsValid(text)) { DoSomeLogging(); } else { switch (text) { case "1": DoSomething(); break; case "2" DoSomethingElse...

I think it's a good idea to separate "validation" and "processing" .
If (IsValid(text)) { switch (text) { case "1": DoSomething(); break; case "2" DoSomethingElse(); break; default: break; } }
I wouldn't want to combine them even if I could .

Suppose you have a method with some pre and post-conditions. Is it ok to create an exception class for each pre-condition that is not accomplished? For example: Not accomplishing pre1 means throwing a notPre1Exception instance.

Just a general 'precondition failed' although you could also have a single 'preconditions failed' exception and put what preconditions have failed into the exception message.

God: An eternally omniscient being
Rough sketch of the argument:
1. By definition, one who isn't omniscient doesn't know at least one proposition: A.
2. For such a person to claim to know proposition B is false if B is predicated on A.
3. For him to know...

If you can inspect the network traffic in any way, then a simple way to detect this is to examine the request .
It's not really connection pooling, but the HTTP keep-alive mechanism that this document discusses .
