Is “while (true)” usually used for a permanent thread?

Question

I\'m relatively new to coding; most of my \"work\" has been just simple GUI apps that only function for one thing, so I haven\'t had to thread much.

Anyway, one thing I\

I had the same problem and tried several methods, keeping an eye on the CPU % which in my case was really important. Here the results:

while (true) {} //this is the worst CPU-consuming one: 30% in my case.

The above, in terms of performance, is the worst (takes more CPU % than any other method, 30% on my project, on my pc). Much better the next one:

while (true) {thread.sleep(1);} //5% cpu, in my case

The above is good in terms of CPU % (around 5% in my case), but not very much elegant:

Console.Readline(); //4% cpu in my case, but for very specific projects

The above is usable only in specific cases, and it's good if you have a console .net application running on background that will never be able to capture a keypress. Still not much elegant, but takes around 4% of CPU in my particular case.

ManualResetEvent resetEvent = new ManualResetEvent(false);
resetEvent.WaitOne(); // WINNER: 4% cpu in my case, and very elegant also.

The above, in my opinion, is the best one: elegant and low CPU consuming (4% in my case). You simply wait for a resetEvent that will never happen. Low CPU% on waiting, and elegant. Also, you can make terminate the infinite waiting by calling "resetEvent.Set()", even from another thread...
