C# 手动激活一个事件

Question

i have a Button with a click event in the background. Can i use this method in another timer triggered event?

 private void bt_Disconnect_Click(object sender, RoutedEventArgs e) 
        {
            if(ser.disconnect())
            {
                img_Ampel.Source = ampeln[0];
                bt_Connect.IsEnabled = true;
                bt_Disconnect.IsEnabled = false;
            }

        }

Thats the click event. The following snippet is the timer trigger.

private void polling_tick(object sender, EventArgs e)
    {
        if (!serial_port.IsOpen)
        {
            mw.Show("Die Verbindung ist abgebrochen!", "Bitte schließen Sie das Gerät wieder an uns klicken Sie auf Verbinden.");
            polling.Stop();
            MainWindow.bt_Disconnect_Click();
        }
    }

Answer 1

Separate logic and event handling.
The simplest way is to extract method:

private void DoSmth()
{
    if(ser.disconnect())
    {
        img_Ampel.Source = ampeln[0];
        bt_Connect.IsEnabled = true;
        bt_Disconnect.IsEnabled = false;
    }
}

private void bt_Disconnect_Click(object sender, RoutedEventArgs e)
{
    DoSmth();
}

private void polling_tick(object sender, EventArgs e)
{
    if (!serial_port.IsOpen)
    {
        mw.Show("...");
        polling.Stop();
        DoSmth();
    }
}

Answer 2

If you really want to to raise the Click event of a button you can use PerformClick() method of button.

yourbutton.PerformClick();

This method can be called to raise the Click event.
