C# WebBrowser网站超时
这是用于Visual Studio Express 2012中的桌面C#应用程序 我正在使用webBrowser控件登录各种网站，但发现一些网站没有响应并超时 我怀疑可能是webBrowser控件本身运行IE7，但发现这些网站在一台运行IE7作为本机浏览器的旧PC上运行良好。webBrowser中是否有我需要设置的内容，以允许下面代码中的网站处理响应 下面的代码导航到一个我遇到问题的网站。如果在本机浏览器中输入登录名和密码的任何值，它会立即响应并抛出错误，但在webBrowser中，它会坐在那里等待响应并最终超时 任何帮助都将不胜感激 米克C# WebBrowser网站超时,c#,.net,winforms,webbrowser-control,C#,.net,Winforms,Webbrowser Control,这是用于Visual Studio Express 2012中的桌面C#应用程序 我正在使用webBrowser控件登录各种网站，但发现一些网站没有响应并超时 我怀疑可能是webBrowser控件本身运行IE7，但发现这些网站在一台运行IE7作为本机浏览器的旧PC上运行良好。webBrowser中是否有我需要设置的内容，以允许下面代码中的网站处理响应 下面的代码导航到一个我遇到问题的网站。如果在本机浏览器中输入登录名和密码的任何值，它会立即响应并抛出错误，但在webBrowser中，它会坐在那里
我经常使用WenBrowserControl，甚至记不起有一次我并没有遇到任何问题，尤其是控件的browermode。以下是帮助我解决这些问题的一些步骤： 1） 强制应用程序使用InternetExplorer设置： 首先，我建议您尝试在下为应用程序添加注册表项
HKLM\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

考虑实现IE行为匹配。谢谢你的NoSuriTo，它为这个特定的网站创造了魅力！我现在会继续在其他网站上测试。下面是代码的完整工作版本。注意-您可以使用Windows regedit检查此程序所做的注册表设置（我不知道是哪种组合解决了此问题）：您可能不需要所有这些功能。我建议从
功能\u浏览器\u仿真开始，通常这就足够了。谢谢你，我想按照你的建议在Internet Explorer中尝试设置，但是在webBrowser控件中如何进行设置？实际上不可能在控件本身中进行设置。但是控件是基于Internet Explorer的。如果更改IE中的设置，控件将应用这些设置。
