Bad idea. Please, learn about events; and you will see, that, unlike "regular" delegate instances, it is not possible to invoke any event from anywhere except the instance of the class where the event is declared, you cannot even do it in a derived class. And this is done for a good reason; this is an important fool-proof feature.

Please see my past answers:
Since we have multicast delegates, why do we need events?[^],
c# networking windows form[^].

In practice, such thing is never needed. In the second answer referenced above, I explain what to do. You don't really want to fire the event; as you say yourself, you need to execute "code written in…" where? — in the code of event handler. Nothing prevents you to do it; and it has nothing to do with event invocation.

Usually, you would put the actual code in another method and call that method from Button_Click().

Now you can also call that method from your Timer_Tick() method.

Solution 7

C#

private void timer1_Tick(object sender, EventArgs e)
{
   button1.PerformClick();
}

or:

C#

private void timer1_Tick(object sender, EventArgs e)
{
   button1_Click(button1, null);
}

private void button1_Click(object sender, EventArgs e)
{
}

or (this is the preferred solution):

C#

private void timer1_Tick(object sender, EventArgs e)
{
   MyMethod();
}

private void button1_Click(object sender, EventArgs e)
{
   MyMethod();
}

private void MyMethod()
{
}

As Click-handlers usually are running in the GUI thread, and the timer in the thread pool, you should consider testing for InvokeRequired in the button1_Click.

In this case I would use the System.Windows.Forms.Timer
