In C# is a for(;;) safe and what does it really do?

So i recently came across something ive never seen before..

        for (; ; )
        {

        }

What is exactly happening when the feilds are left blank like that?

Answer 1

It’s an infinite loop.

Somewhere inside there should be a break; statement, or possibly an exception thrown in order for control to pass beyond the loop.

You could also achieve the same thing (probably more obviously) by doing

while (true)
{
    // do stuff
}
