Unable waiting for web page loading using WebBrowser control

I am writing a service with screenshots from the web pages of local sites.

I am using WebBrowser control to capture a webpage as an image.

Below is the code I am using:

namespace MakeScreenShotURL
{
class Program
{
private static Config config = new Config(System.Reflection.Assembly.GetExecutingAssembly().Location);
[STAThread]
static void Main()
{
int width = 1700;
int height = 1700;
string username = "userdata";
string password = "passworddata";
int currentmonth = DateTime.Now.Month;
int nextmonth = DateTime.Now.Month + 1;
int year = DateTime.Now.Year;
screen(width, height, year, nextmonth, currentmonth, username, password);
}
static void screen(int width, int height, int year, int nextmonth, int currentmonth, string username, string password)
{
string PlaceCode = config.GetAppSetting("place");
string[] Places = PlaceCode.Split(';'); //contains a list of sites for example: Berlin; Munich; Dresden
foreach (string pl in Places)
{
using (WebBrowser browser = new WebBrowser())
{
browser.Width = width;
browser.Height = height;
browser.ScrollBarsEnabled = true;
Uri uri = new Uri(" http://localsite.php?y=" + year + "&m=" + nextmonth + "&p=" + pl + " ");
string additionalHeaderInfo = "Authorization: Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(username + ":" + password)) + System.Environment.NewLine;
browser.Navigate(uri, null, null, additionalHeaderInfo);
Wait(2); //waiting for pages to load 2 seconds
using (Graphics graphics = browser.CreateGraphics())
using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height, graphics))
{
Rectangle bounds = new Rectangle(0, 0, bitmap.Width, bitmap.Height);
browser.DrawToBitmap(bitmap, bounds);
bitmap.Save("C:/Users/user/image/screenshot" + pl + ".jpeg", ImageFormat.Jpeg);
}
Application.Run();
}
}
Application.Exit();
}
static void Wait(int number)
{
DateTime time = DateTime.Now;
do
{
Application.DoEvents();
}
while (time.AddSeconds(number) > DateTime.Now);
}
}
}

The program creates a screenshot of the first element (Berlin) from the array of Places and saves it to disk.

But when selecting the second element from the array, the program hangs on the execution after the line:

Application.Run ();

Perhaps the program expects something but I cannot understand it.

Can someone help me to?

Application.Run() starts a message loop on the current thread and displays the specified form. The message loop enables the form to receive Windows messages (eg, key presses, mouse clicks, paint invalidations) to allow it to appear responsive and have interaction with the user.

But in your case, it is not needed as you are not doing any actions on the control. You can directly skip this statement.

Application.Run starts a message loop, but do you really need it?
