c＃console应用程序WebBrowser ReadyState永远不会完成

Question

我使用WebBrowser从一些网页中删除数据，该网页的javascript加载时间为5-8秒。 （wb.ReadyState！= WebBrowserReadyState.Complete）永远不会发生。怎么会这样？

public static String data { get; set; }
[STAThread]
static void Main(string[] args)
{
    string pathToWrite = @"C:\ABC.csv";
    string nodelist = @"C:\WebPagelist.txt"; //{"001", "abc.com/mvc/001" /r/n "002", "abc.com/mvc/002" /r/n "003", "abc.com/mvc/003" /r/n ... "499", "abc.com/mvc/499"}
    string line;
    using (StreamReader reader = new StreamReader(nodelist, Encoding.UTF8))
    {
        while ((line = reader.ReadLine()) != null)
        {
            string[] node = line.Split('\t');
            Download(node[0], node[1]);
        }
    }
    using (var PlayerFile = new StreamWriter(pathToWrite, true))
    {
        PlayerFile.Write(data);
        PlayerFile.Flush();
    }
}
static void Download(string cityName, string url)
{
    WebBrowser wb = new WebBrowser();
    wb.ScriptErrorsSuppressed = true;
    wb.Navigate(url);

    while (wb.ReadyState != WebBrowserReadyState.Complete)
    {
         Application.DoEvents();
    }
    string A = wb.Document.GetElementById("cur_A").InnerText;
    string B = wb.Document.GetElementById("cur_B").InnerText;
    string C = wb.Document.GetElementById("cur_C").InnerText;
    data  += A + "," + B +"," + C + + Environment.NewLine;
}
