问题 In ASP.NET MVC 2, a couple of new action filter attributes were introduced, as "shorthand" for attributes in ASP.NET MVC 1; for example, applying the HttpPostAttribute does the same thing as applying [AcceptVerbs(HttpVerbs.Post)] to an action method. In addition, with the more verbose syntax, it is possible to combine different methods, in order to allow for example both Post and Delete . Now I'm wondering: how do the new attributes work? If I apply both [HttpPost] and [HttpDelete] , will ASP

问题 I am receiving this error when trying to use RedirectToAction, can anyone offer any advice on why this could be occuring, ive used this before without any problems, i must be missing something. Cannot implicitly convert type 'System.Web.Mvc.RedirectToRouteResult' to 'System.Web.Mvc.ViewResult' [HttpPost] public ViewResult Edit(Customer customer) { if (ModelState.IsValid) { customersRepository.SaveCustomer(customer); TempData["message"] = customer.CustomerName + " has been saved."; return

问题 I'm trying to use HTML Agility Pack to append a script element into the top of the HEAD section of my html.

How can I specify this? Here's what I'm trying: HtmlDocument htmlDocument = new HtmlDocument(); htmlDocument.Load(filePath); HtmlNode head = htmlDocument.DocumentNode.SelectSingleNode("/html/head");

问题 I am using EF4 in my ASP.NET MVC 2 web application. I am attempting to save data to a database. It is fairly straightforward to add new data to a database. I'm doing it something like this: PeopleEntities entities = ObjectContextFactory.GetPeopleEntities(); entities.People.AddObject(person); // The Person object created from user input. entities.SaveChanges(); However, this has the unfortunate side-effect of always saving a new object to my database. I do need this functionality (of course),

问题 I'm trying to get ASP.NET MVC 2 single-project area registration to work. Tried with Preview 2 and now with Beta version with no luck. I used the "Add area" dialog to create a "NewsModule" area. Created a NewsModuleController inside it and an Index view for it. The route registration for this Area looks like this: context.MapRoute( "NewsModule_default", "NewsModule/{action}/{id}", new { action = "Index", id = "", controller = "NewsModule", area = "NewsModule" } ); I added the AreaRegistration

But then this does not... public class BaseService { [Inject] public IRoundRepository
