C# WebBrowser 控制代理

Question

如何在 C# WebBrowser 控件/组件中实现代理。

我想知道的是如何实现代理，所以我的 C# webBrowser 控件在运行时使用这个代理进行浏览。

我也不想通过注册表更改代理...因为它会影响我的正常浏览...

private Uri currentUri;

        private void Form1_Load(object sender, EventArgs e)
        {
            currentUri = new Uri(@"http://www.stackoverflow.com");
            HttpWebRequest myRequest = (HttpWebRequest) HttpWebRequest.Create("http://www.stackoverflow.com");
            //WebProxy myProxy = new WebProxy("208.52.92.160:80");
            //myRequest.Proxy = myProxy;

            HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();

            webBrowser1.DocumentStream = myResponse.GetResponseStream();

            webBrowser1.Navigating += new WebBrowserNavigatingEventHandler(webBrowser1_Navigating);
        }

        void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
        {
            if (e.Url.AbsolutePath != "blank")
            {
                currentUri = new Uri(currentUri, e.Url.AbsolutePath);
                HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create(currentUri);

                HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();

                webBrowser1.DocumentStream = myResponse.GetResponseStream();
                e.Cancel = true;
            }
        }

您需要稍微玩一下，但我可以浏览该网站。

或者您可以尝试修改 WebRequest.DefaultWebProxy 设置： http://msdn.microsoft.com/en-us/library/system.net.webrequest.defaultwebproxy.aspx
