Question

I have a web page that when navigated to only returns a simple text value, like the number 100. I need to grab that value from the page, so I can use it in my application. The application is a simple Windows Forms app, with a web browser control on it.

I have tried numerous things, but it’s not grabbing the text, as if it doesn’t exist. Yet if I right click and view source, it’s there.

This can’t be that difficult…It’s just some text.

Just to clarify the document contains NO html, only a number. When using WebClient or WebRequest, it doesn’t return the value.

    private void RegisterWindow_Load(object sender, EventArgs e)
    {
        webBrowser1.Navigate("MYURL");
        webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);

    }

    void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        // Check and see if we have navigated to the final page.
        string registeredUrl = "MYURL";
        string currentPage = webBrowser1.Url.ToString();
        string response = string.Empty;

        if (webBrowser1.Url.ToString() == registeredUrl)
        {
            // Now parse the authkey from the url
            response = GetWebRequest(currentPage);
            MessageBox.Show(response);
        }
    }

    /// <summary>
    /// Send a Web Request and get a Web Response back. 
    /// This respons can be a valid URL, simple text response, or 
    /// HTML response.        
    /// </summary>
    /// <param name="url"></param>
    /// <returns></returns>
    public string GetWebRequest(string url)
    {
        var client = new WebClient();
        var content = client.DownloadString(url);

        return content;
    }

If the document contains only number without any HTML, this should work:

public string GetWebRequest()
{
    return webBrowser1.Document.Body.InnerText;
}
