On a new thread, also turn illegalcrossthreading off

while (true)
{
Thread.sleep(10000);
button1.enabled = !button1.enabled;
}

Please dont use thread.sleep() if you really need this feature check system time. then have a whille loop that says while currenttime < time + 10
buutton is unclickable

The correct way to do it is:

Code

var timer = new Timer { Interval = 10000 };
t.Tick += delegate { button1.Enabled = !button1.Enabled; };
t.Start();

Please don't.
Also,

There isn't a correct or wrong way to do this.

Okay, let me paraphrase:

The easiest and cleanest way to do it.

actually yes there is, because this will turn the button on and off every 10 seconds. Not what the OP wants. What if he doesn't click it in the 10 seconds? it'll disable it for the next 10.

Oops, my bad. That's what you get for only reading the title. 🤦‍♂
