How to Implement Timer Interval and Start

Question

1.00/5 (2 votes)

See more:

I want a situation that when I start my timer, it doesn't tick at its interval first before performing an action. For example, I want to display a label text on my form after I click a button with a 5 second interval but instead after the button is clicked, there is a 5 second delay before the label text is shown. How can I solve this issue?
Code looks something like this:

C#

private void btnSet_Click(object sender, EventArgs e)
{
   timer1.Enabled = true;
   timer1.Start();
   timer1.Interval = 5000;
}

private void timer1_Tick(object sender, EventArgs e)
{
   label1.Text = "Hello";
}

You need to provide complete scenario like:
1. Windows/Web application
2. What is the code you are using(not complete code only which are related to Question)

code provided

Your code says, "wait five seconds, then set the label's text".

Therefore, it's not surprising that the code waits five seconds before setting the label's text.

If you don't want a five second delay before setting the label's text, then don't use a Timer to wait for five seconds before setting the label's text.

If you do want the delay, then you're going to have to explain what the problem is.

not that related, but
timer1.Enabled = true;
timer1.Start();

is exactly the same. ;)
you can use either one

Solution 1

Write your action as a function and call the function before the timer starts

Your code is probably like this

C#

timer.Start();

void timer_click()
{
    // some code
}

change it to

C#

myFunction();
timer.Start();

void timer_click()
{
    myFunction();
}
void myFunction()
{
    // some code
}

Same there is still the timer interval occurring before the function

Manas_Kumar · Answer 2 · 2015-10-13T04:39:00

Try with below code:

C#

private void btnSet_Click(object sender, EventArgs e)
{
   timer1.Enabled = true;
   timer1.Interval = 5000;
   timer1.Tick += new EventHandler(timer1_Tick);
   timer1.Start();
   
}
 
private void timer1_Tick(object sender, EventArgs e)
{
   label1.Text = "Hello";
}

You can do this by declaring an inline delegate like:

C#

private void btnSet_Click(object sender, EventArgs e)
{
   var t = new Timer();
   t.Interval = 5000;
   t.Tick += (s, e) =>
   {
       label1.Text = "Hello";
       t.Stop();
   };
   t.Start();
}

where s, e two arguments are Object sender, EventArgs e.

This unfortunately doesn't solve the problem, timer tick still occurring before action
