Answer 1

The problem is that the signature of your test() method:

public static void test()

doesn't match the required signature for TimerCallback:

public delegate void TimerCallback(
    Object state
)

That means you can't create a TimerCallback directly from the test method. The simplest thing to do is to change the signature of your test method:

public static void test(Object state)

Or you could use a lambda expression in your constructor call:

Timer x = new Timer(state => test(), null, 0, 1000);

Note that to follow .NET naming conventions, your method name should start with a capital letter, e.g. Test rather than test.
