What does “for(;;)” do in C#?

what does

for (; ; )
{
  // do something
}

mean in c#?

Isn’t there supposed to be (initializer, condition, iterator) ?

I saw an example in a book that uses nothing inside the contents of the for loop.

Answer 1

That would create an unconditional (infinite) loop which has no initializer or iterator.

same as

while(true)
{
...
}

You’ll have to use break; to get out of the loop.
