How to make progress bar sync with page load (C #)? ?

tietie

detail? The WebBrowser type will return the progress that has been reached through the ProgressChanged event when the download progress changes. So you only need to handle this event to update the properties of ProgressBar, just like the example above.

How is the ProgressChanged event implemented?
I still don’t quite understand, just like the program written inwudi1982, who can explain to me in detail~
private void Form1_Load(object sender, EventArgs e)
        {
            Uri url = new Uri("http://www.163.com");
            webBrowser1.Url = url;
            webBrowser1.ProgressChanged+=new WebBrowserProgressChangedEventHandler(webBrowser1_ProgressChanged);
        }

        private void webBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
        {
            
            processBar.Visible = true;
            if ((e.CurrentProgress> 0)&&(e.MaximumProgress> 0))
            {
                processBar.Maximum =Convert.ToInt32( e.MaximumProgress);
                processBar.Step = Convert.ToInt32(e.CurrentProgress);
                processBar.PerformStep();
            }
            else if (webBrowser1.ReadyState == WebBrowserReadyState.Complete)
            {
                processBar.Value = 0;
                processBar.Visible = false;
            }
        }
