App_code Folder issues

So I'm having a really weird issue with my App_Code folder on a new website I'm designing.

I have a basic class inside of a namespace in the App_Code folder. Everything works fine in the IDE when I setup the namespace and make an object from the class. It brings up the class summary on hover, and when you click on "go to deffinition" it goes to the class file. And it also works fine localy.

Ans:The problem that your classes are not compiled, You'll solve this issue simply by going to the properties of any class in the App_Code folder and change it's 'Build Action' property from "Content" to "Compile"

c# save contents of IE browser as html

If you embed a WebBrowser control inside of your WinForm you can do this:

webBrowser1.Navigate("http://google.com");
string pageHtml = webBrowser1.Document.GetElementsByTagName("html")[0].InnerHtml;


This will return all of the HTML in the page navigated to.

protected override void Render(HtmlTextWriter writer)
{
    using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new System.IO.StringWriter()))
    {
        base.Render(htmlwriter);
        string html = htmlwriter.InnerWriter.ToString();


        using (FileStream outputStream = new FileStream(@"C:\\temp.html", FileMode.OpenOrCreate))
        {
             outputStream.Write(html, 0, html.Length);
             outputStream.Close();
        }

        writer.Write(html);
    }
