问题 I'm trying to setup an action filter that only does something if the StatusCode of the HttpContext.Response is 302. I would expect to be able to do this in the OnActionExecuting method, but the StatusCode is always 200 .

问题 As I'm trying to understand them, It seem like they are both used to route/map the request to a certain endpoint 回答1: First of all,you could have a look at their source code: 1.UseRouting public static IApplicationBuilder UseRouting(this IApplicationBuilder builder) { if (builder == null) { throw new ArgumentNullException(nameof(builder)); } VerifyRoutingServicesAreRegistered(builder); var endpointRouteBuilder = new DefaultEndpointRouteBuilder(builder); builder.Properties[EndpointRouteBuilder

问题 I have a page with server side rendering using razor, where you can add a couple of elements from different lists, fill some fields and create a request from it on submit. Each time an item is added/taken from any list, I send a post with submit button to a specific action, e.g. "CustomerSelected". I do this, because I need to recreate additional view components for the added item. In these methods I would like to add added objects to the db context, so on submit I can just say SaveChanges()

问题 In ASP.Net MVC 5, custom data annotation validator can be implemented by inheriting DataAnnotationsModelValidator and registering using DataAnnotationsModelValidatorProvider.RegisterAdapter(...) . In ASP.Net Core MVC, how can I achieve this? I found similar question at ASP.net core MVC 6 Data Annotations separation of concerns, but can anyone show me simple example code? 回答1: It seems to me ASP.NET Core MVC does not have support for DataAnnotationsModelValidatorProvider.RegisterAdapter

问题 I used to have a UserFactory (before vNext) that used HttpContext.Current but since that is now gone I am having trouble recreating it. I want it to be a static class that sets and gets the current user to access user data throughout the application. I know I must use the DI system but not sure how. Code so far: public class CurrentContext : IHttpContextAccessor { private IHttpContextAccessor ctx; public HttpContext HttpContext { get { return ctx.HttpContext; } set { ctx.HttpContext = value;
