条件为假时执行 IF 语句 C#

Question

• I tried disabling the button at first but that didn't work
• Therefore I created a variable to prevent it from running the code inside the IF. For some weird reason it doesn't work, when I try to click it before the sleep it executes right after the time is over.

So if I click the Button

• one time it sleeps for 2 seconds,
• if I double click it it sleeps for 4 seconds (etc) despite that it should only sleep for 2 seconds.

This should make so the code would only executes after the buttons are enabled again. (The buttons being disabled is just for the looks)

Note:Variable "button_enabled" is global

 private void senha_b_Click(object sender, EventArgs e)
    {
        if (button_enabled == 1)
        {
            button_enabled = 0;
            wait_label.Show();
            senha_a.Enabled = false;
            senha_b.Enabled = false;
            senha_c.Enabled = false;

            System.Threading.Thread.Sleep(2000);

            wait_label.Hide();
            senha_a.Enabled = true;
            senha_b.Enabled = true;
            senha_c.Enabled = true;
            button_enabled = 1;
        }
    }

This should fix it

 private async void senha_b_Click(object sender, EventArgs e)
    {
        if (button_enabled == 1)
        {
            button_enabled = 0;
            wait_label.Show();
            senha_a.Enabled = false;
            senha_b.Enabled = false;
            senha_c.Enabled = false;

            await Task.Delay(2000);

            wait_label.Hide();
            senha_a.Enabled = true;
            senha_b.Enabled = true;
            senha_c.Enabled = true;
            button_enabled = 1;
        }
}
