我正在尝试从Web浏览器控件切换到http请求以自动执行任务以提高速度.使用此功能,我可以发布数据并接收登录页面,但不会返回任何cookie并将其添加到cookie列表中,因此登录的会话不会传递给下一个请求.

    //an example call        
    test("http://websitename.com/loginpage.php", "username=foo&password=123456");

    private string test(string url, string data)
    {
        string responseFromServer;

        byte[] byteArray;

        Stream dataStream;

        HttpWebRequest request;

        HttpWebResponse response;

        StreamReader reader;


        responseFromServer = string.Empty;

        try
        {
            request = WebRequest.Create(url) as HttpWebRequest;
            request.Method = "POST";
            request.KeepAlive = true;
            request.ContentType = "application/x-www-form-urlencoded";

            byteArray = Encoding.UTF8.GetBytes(data);
            request.ContentLength = byteArray.Length;

            request.CookieContainer = new CookieContainer();

            foreach(Cookie a in cookies)
                request.CookieContainer.Add(a);

            dataStream = request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();

            response = request.GetResponse() as HttpWebResponse;

            foreach(Cookie a in response.Cookies)
                cookies.Add(a);

            dataStream = response.GetResponseStream();

我使用WebBrowser控件导航到WordPress博客的登录页面.页面加载正常,但每当我尝试从一个线程访问WebBrowser时.我得到一个特定的演员是无效的例外.同样在调试时,一切都冻结了大约5秒钟.调试时,我尝试访问控件.我得到了所有成员变量的错误.

//in constructor of main form
Thread.CurrentThread.ApartmentState = ApartmentState.STA;
this.CheckForIllegalCrossThreadCalls = false;

mainThreadHandle = new Thread(mainThread);
mainThreadHandle.Start();

private void mainThread()
{
    wbMain.Navigate("http://example.com/");

    //navigating is set to false in the document complete event.
    navigating = true;

    while (navigating == true)
        Thread.Sleep(5000);

    try
    {
        //Where I get the issues
        MessageBox.Show(wbMain.DocumentText);
    }
    catch (Exception e)
    {

    }

    Thread.Sleep(1000);
}

我一直在尝试通过设备上下文句柄获取窗口的句柄。我尝试过 WindowFromDC() ，它不断返回空结果。如何从任何设备上下文获取窗口句柄？

我有一个加载到多个进程的DLL.什么是一个干净的方式来沟通这些进程/ dll.发送简单字符串是目标.我宁愿避免sendmessage,file io和发送string命令的地址.
