❔ Help to close a forms from another forms C#

I created 2 scripts with a timer with intervals of 1000 ms, both one is to open a new form when a certain process is started, this side is working fine, and the other is to close the same forms when the given process is closed, I've tried several times forms and I can't close the forms that were opened when the process is finished, could someone help me?

private void timer2_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 1)
    {
        frmTimer tm = new frmTimer();
        tm.Show();
        
        timer2.Stop();
    }
}

///


private void timer1_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 0)
    {
        frmTimer tm = new frmTimer();
        tm.Close();
       
        timer1.Stop(); 
    }
}

private void timer2_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 1)
    {
        frmTimer tm = new frmTimer();
        tm.Show();
        
        timer2.Stop();
    }
}

    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 0)
    {
        frmTimer tm = new frmTimer();
        tm.Close();
       
        timer1.Stop(); 
    }
}

In this example, these are 2 separate instances of frmTimer You're closing a different one

yes one instance to open and another to close?

No, instance. Like you can open that form 2 times. And they're 2 separate entities. You can close one and keep the other one open What you probably want to do is declare the frmTimer outside of the methods so you have access to the same instance of the form inside of both methods

frmTimer tm = new frmTimer();
private void timer2_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 1)
    {        
        tm.Show();
        
        timer2.Stop();
    }
}

///


private void timer1_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 0)
    {
        tm.Close();
       
        timer1.Stop(); 
    }
}

frmTimer tm = new frmTimer();
private void timer2_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 1)
    {        
        tm.Show();
        
        timer2.Stop();
    }
}

///


private void timer1_Tick(object sender, EventArgs e)
{
    Process[] processes = Process.GetProcessesByName("teste");

    if (processes.Length == 0)
    {
        tm.Close();
       
        timer1.Stop(); 
    }
}

There might be better ways to do that, but at least that should function the way you're intending it to
