How to post url in C#

I need to "post" a web url in the background and repeat it every 60 seconds. Would prefer not to use the Windows Scheduler.

For example....
http://www.domain.com/index.php?userkeepalive=user1

I don't need to view the page - just hit the url. (Kind of like curl). How would I do this in C#?

I would do it in a different way and not let the thread sleep for a minute every time. You can use a Timer control to do work on a timed interval.

public class Example {
    private Timer timer;
    private WebClient client;

    public Example() {
        this.client = new WebClient();
        this.timer = new Timer();
        this.timer.Interval = 60000;
        this.timer.Tick += new EventHandler<EventArgs>(timer_Tick);
        this.timer.Enabled = true;
    }

    private void timer_Tick(object sender, EventArgs e) {
        this.client.DownloadString("http://www.example.com");
    }
}

Open in new window

Also, the WebClient's DownloadString requests (HTTP GET) a URL whereas the UploadString performs a HTTP POST.

What is the difference between UploadString and DownloadString?

If it's a Console application, does it really matter?

As CodeMasterAlex indicated, you would use UploadString to perform a POST.

@kaufmed:

I don't know what kind of application it is. I don't think it would really matter, it is more a matter of preference. Reading the remarks at http://msdn.microsoft.com/en-us/library/system.timers.timer%28v=vs.100%29.aspx suggests it is a better option in this case.
