Access HttpContext.Current from different threads

由 痴心易碎 提交于 2019-11-26 18:38:51
I have a C# ASP.NET application which starts about 25 different threads running some methods in a class called SiteCrawler.cs. In HttpContext.Current.Session I want to save the result of the search made by the user and present it to the user when all the threads are finished running. My problem is that the HttpContext.Current object is null in the spawned threads because it doesn't exist there. What other options do I have to save user/session specific data without using session because of the limitations when the application is multithreaded? I have tried to search around every inch of

问题 I've been trying to get the "new" ZipArchive included in .NET 4.5 ( System.IO.Compression.ZipArchive ) to work in a ASP.NET site. But it seems like it doesn't like writing to the stream of HttpContext.Response.OutputStream . My following code example will throw System.NotSupportedException: Specified method is not supported as soon as a write is attempted on the stream. The CanWrite property on the stream returns true. If I exchange the OutputStream with a filestream, pointing to a local

HttpSelfHostServer and HttpContext.Current

由 荒凉一梦 提交于 2019-11-26 13:18:38
问题 I'm working on a self-hosted ASP.NET web api-application. Everything works fine, but now I'm struggling with HttpContext : I need to save session-informations from the client. But HttpContext.Current is always null. So it's obvious that my HttpSelfHostServer don't work with the static HttpContext-Class. The thing I don't understand is: why..? And I can't figure out a way to tell neither HtttpSelfHostServer nor HttpSelfHostConfiguration to work with HttpContext . Here's what I'm doing:

Get current System.Web.UI.Page from HttpContext?

由 寵の児 提交于 2019-11-26 12:38:27
问题 This is actually a two part question. First,does the HttpContext.Current correspond to the current System.UI.Page object? And the second question, which is probably related to the first, is why can\'t I use the following to see if the current page implements an interface: private IWebBase FindWebBase() { if (HttpContext.Current as IWebBase != null) { return (IWebBase)HttpContext.Current.; } throw new NotImplementedException(\"Crawling for IWebBase not implemented yet\"); } The general context

How to get working path of a wcf application?

由 允我心安 提交于 2019-11-26 09:24:26
问题 I want to get the working folder of a WCF application. How can I get it? If I try HttpContext.Current.Request.MapPath(HttpContext.Current.Request.ApplicationPath) I get a null reference exception (the Http.Current object is null). What I meant with the working folder was the folder where my WCF service is running. If I set aspNetCompatibilityEnabled=\"true\" , I get this error: The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session
