我正在使用webbrowser控件登录任何网站.然后我想使用WebRequest(或WebClient)下载一些子页面html.此链接必须要求身份验证.
如何将Webbrowser身份验证信息传输到Webrequest或Webclient？
当我在我的Fedora 20工作站上使用xsp4(来自MonoDevelop或直接)运行我的ASP.NET MVC 4网站时,我遇到以下异常:
System.Web.HttpRuntime.FinishWithException (wr={Mono.WebServer.XSPWorkerRequest}, e={System.Web.HttpException: ---> System.Web.HttpException: The pre-application start initialization method Start on type System.Web.WebPages.PreApplicationStartCode threw an exception with the following error message: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: An exception was thrown by the type initializer for <Module> ---> System.Security.SecurityException: No access to the given key ---> System.UnauthorizedAccessException: Access to the path "/etc/mono/registry" is denied.
at System.IO.Directory.CreateDirectoriesInternal (System.String …string remoteUri = "http://www.contoso.com/library/homepage/images/";
string fileName = "ms-banner.gif", myStringWebResource = null;
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Concatenate the domain with the Web resource filename.
myStringWebResource = remoteUri + fileName;
Console.WriteLine("Downloading File \"{0}\" from \"{1}\" .......\n\n", fileName, myStringWebResource);
// Download the Web resource and save it into the current filesystem folder.
myWebClient.DownloadFile(myStringWebResource,fileName);
Console.WriteLine("Successfully Downloaded File \"{0}\" from \"{1}\"", fileName, myStringWebResource);
Console.WriteLine("\nDownloaded file saved in the following file system folder:\n\t" + Application.StartupPath);
我在MSDN网站上使用此代码 …
