C# 访问文件文件夹时Webbrowser控件身份验证不工作
我有一个.Net 2.0 WinForm应用程序,它有一个WebBrowser控件,用于访问一个安全的网络驱动器,这个网络驱动器只允许访问几个特殊帐户,应用程序需要模拟一个读卡器帐户来读取PDF文件 我使用了LogonUser,应用程序能够模拟reader帐户来查看文件夹下的文件名,但是当我使用webBrowser1.Navigate(newURI(filePath))m时,我的访问被拒绝 所以经过研究,我知道我必须做一些我以前从未用过的东西。好的,经过几个小时的在线和尝试/错误后,我使用了IAuthenticate、IOleClientSite、IServiceProvider,我找到了结构,它可以很好地使用提供的用户凭据访问安全网站,它不会弹出框询问用户名和密码,并且会正确打开网站 然而,如果我将网站URL替换为安全的文件路径,它根本不起作用 webbrowser访问此处的安全网站实际上不需要LogOnUser模拟内容。但我不知道访问文件夹是否需要它。我尝试添加LogOnUser并包装webbrowser.Navigate(路径),但没有帮助 为什么这适用于网站而不是文件夹 我使用的完整测试代码粘贴在这里:C# 访问文件文件夹时Webbrowser控件身份验证不工作,c#,winforms,authentication,browser,webbrowser-control,C#,Winforms,Authentication,Browser,Webbrowser Control,我有一个.Net 2.0 WinForm应用程序,它有一个WebBrowser控件,用于访问一个安全的网络驱动器,这个网络驱动器只允许访问几个特殊帐户,应用程序需要模拟一个读卡器帐户来读取PDF文件 我使用了LogonUser,应用程序能够模拟reader帐户来查看文件夹下的文件名,但是当我使用webBrowser1.Navigate(newURI(filePath))m时,我的访问被拒绝 所以经过研究,我知道我必须做一些我以前从未用过的东西。好的,经过几个小时的在线和尝试/错误后,我使用了IA
