this question has answer here: is there alternative using % (modulus) in c/c++? 12 answers i have code segment requires remainder of 2 ints. using modulus operator usual hearing takes more time. asking there way remainder more efficiently mod operation... following code int rem=gid%bpp gid being int , bpp being 2,4,8,16,32. it appears question bpp power of 2, in case can use instead: int rem = gid & (bpp - 1); however should not optimise prematurely - unless have profiled , know mod operation bottleneck should leave in original, more readable form.

lock { dispatcher.begininvoke(dispatcherpriority.send, (sendorpostcallback)delegate(object o) { dosomething(); } } does lock remains acquired until dispatcher completes execution or released after sending dosomething(); execution dispatcher? lock remains acquired until code under lock {} section completes execution. in case means: until dispatcher.begininvoke completes execution. and dispatcher.begininvoke executes asynchronously, means lock gets released "immediately" - dosomething() might start in moment when lock has been released.
