阻止显示Windows安全窗口
我有一些路由器配置页面URL，我必须加载它们，设置并保存它。 我正在使用webbrowser控件和.Net 4.5和C＃语言。 但每次加载页面时，都会弹出Windows安全性并要求输入用户名和密码。 它适用于每个URL。 我怎么能阻止这个？ 所有URL的用户名和密码都相同。 如何使用硬编码为所有这些设置用户名和密码？！ 
您需要通过IServiceProvider为WebBrowser对象提供IAuthenticate COM接口的实现。 当WebBrowser处理需要基本或Windows身份validation的资源时，将调用IAuthenticate::Authenticate实现，这样您就有机会提供正确的用户名和密码。
下面是如何通过WebBrowser的IProfferService完成此操作的完整示例。

我在微软的论坛上发现了这个：
WebBrowser和基本身份validation
我发现答案很简单…..
Uri u = new Uri("http://your_domain"); UriBuilder ub = new UriBuilder(u); ub.UserName = "username"; ub.Password = "password"; webBrowser1.Url = ub.Uri;
