问题 In tag helpers, we can access the tags inner HTML. <!-- Index.cshtml --> <my-first> This is the original Inner HTML from the *.cshtml file. </my-first> // MyFirstTagHelper.cs > ProcessAsync var childContent = await output.GetChildContentAsync(); var innerHtml = childContent.GetContent(); If we invoke a view component as a tag helper, how can we access the inner HTML? <vc:my-first> This is the original Inner HTML from the *.cshtml file. </vc:my-first> // MyFirstViewComponent.cs > InvokeAsync()

问题 Been trying to get a grip of ASP.NET Core MVC but got stuck with dependency injection returning empty collection in my controller action, despite of registering the service as Singleton in ConfigureService method. Tried two different ways to register but only one of them actually works. Said method is as following: public void ConfigureServices(IServiceCollection services) { // Add framework services. services.AddMvc(); /***THIS DOES NOT WORK***/ services.AddSingleton<IRepository<Employee>,

问题 I have created a ModelBinder, which only gets triggered if an object has a [Decimal] attribute assigned, yet for some reason, despite it actually sanitising the data it does not seem to update the posted model. I wonder if someone could see from my code below, where I maybe going wrong. Startup.cs public void ConfigureServices(IServiceCollection serviceCollection) { serviceCollection.AddMvc(config => config.ModelBinderProviders.Insert(0, new DecimalModelBinderProvider())); }

问题 I keep getting the following error when I try to debug my .NET-Core application: An error occurred attempting to determine the process id of Test.exe which hosting your application I have googled around and I see many having this problem with SSL. But I don't have SSL. I have also tried to remove the json lock file, but that don't work either.. Should I modify something in project.json? Here is my project.json: { "userSecretsId": "aspnet-Testar-0b0a75f7-4784-4192-a127-a1a4183a2709",

问题 I am trying to get asp.net core MVC to scaffold a Razor View with fields in a different order than the apparently default alphabetical order. I've got a simple model: public class Application : EntityBase { [Display(Name = "Naam", Order = 1)] public string Name { get; set; } [Display(Name = "Omschrijving", Order = 2)] public string Description { get; set; } } I want the scaffolder to generate a field for Name before Description. How to do this? I've been trying to come up with a solution in

问题 I cant get my resource files loaded, or some thing else is keeping my app to load correct values. This is from my Startup.cs: services.AddLocalization(opts => { opts.ResourcesPath = "Resources"; }); services.AddMvc() .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix, opts => { opts.ResourcesPath = "Resources"; }) .AddDataAnnotationsLocalization(); services.Configure<RequestLocalizationOptions>(options => { var supportedCultures = new[] { new CultureInfo("da-DK") }; options

问题 I am using asp.net core mvc. Next to default authentification I have added very specific authorization which is done by using ResultFilterAttribute attribute. In future, to make sure that developers are going to specify permissions for each controller method I would like to check if the attribute is set for method, before action is executed. Can it be done in MVC middleware. Or maybe there is better approach? 回答1: Thanks to Christian for mentioning ControllerFactory . It was right approach in

问题 I have a custom route that reads URLs from a no-SQL database (MongoDB) and add them to the route pipeline at moment that the application starts, which is "pretty standard" something like this (in my startup.cs file): app.UseMvc(routes => { routes.MapRoute( "default", "{controller=Home}/{action=Index}/{id?}"); routes.Routes.Add( new LandingPageRouter(routes, webrequest, memoryCache, Configuration)); // this custom routes adds URLs from database } the issue is that if I add another route to the

问题 I have static helper class public static class Current { public static string Host { get { return "httpContextAccessor here"; } } } How I can get access to current HttpContext inside Host property? 回答1: You can't and you shouldn't. This beats the whole purpose of having a dependency injection system at all. Static classes (for runtime data or Service Locator) is an anti-pattern. In ASP.NET Core you have to inject IHttpContextAccessor in classes where you need it. You can make a non-static
