c# - Is there any difference between declare variable in/out for? -

-

possible duplicate:
declaring variable inside or outside foreach loop: faster/better?

hi all,

what difference between 2 examples or there any?

ex 1:

for (int = 0; < 2; i++) {     thread newthread = new thread( ... );     newthread.start(); }

ex 2:

thread newthread; (int = 0; < 2; i++) {     newthread = new thread( ... );     newthread.start(); }

their il codes same...

in second example, can access last thread newthread, not possible in first example.

one more difference: second example holds reference last thread, garbage collector can't free memory when thread finished , disposed.

the new keyword allocates memory, there no difference in memory allocation (see this link).
