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？！
解决方法
您需要通过
IServiceProvider向Webbrowser对象提供
IAuthenticate COM接口的实现.当Webbrowser处理需要Basic或Windows身份验证的资源时,将调用IAuthenticate :: Authenticate的实现,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.
