问题 I have Serilog configured for Asp.Net Core 2.0 and it works great via .Net Core dependency injection in my startup web project (if I use it through Microsoft.Extensions.Logging), but I can't access it from any other project. Here's what I have: Program.cs using System; using System.IO; using Microsoft.AspNetCore; using Microsoft.AspNetCore.Hosting; using Microsoft.Extensions.Configuration; using Serilog; namespace ObApp.Web.Mvc { public class Program { public static IConfiguration

问题 I need to override ASP.NET Core's default registration for a certain controller. I've tried the below, but it resolves MyController from the automatic registration. services.AddTransient((provider) => new MyController(...)); How can I override this? 回答1: By default, controllers are resolved using type activation , which boils down to the framework using an equivalent of Activator.CreateInstance to create controller instances. The dependencies for these controllers are sourced from the DI

问题 I've been stuck on this recently and can't figure out why this is happening. I'm using an MVC Controller in .Net Core to return a NotFound() "404" response. However, client side (using angular) if I console.log the response, it shows this... status:200 statusText:"OK" Is there any reason why returning NotFound() would return an error code of 200 instead of the intended 404? This is my Controller GET. // GET: api/cause/cause-name [HttpGet("{name}")] [AllowAnonymous] public IActionResult

问题 I'm new to ASP.NET core, so I hope you bear with me on this one. This is similar to this unanswered question. When I'm testing a brand new C# MVC project, and I enter a wrong URL, there's no info. Just a blank page. To solve this, I have adapted startup.cs adding a UseStatusCodePagesWithReExecute() to return a static 404.html page. This works. So far, so good. Now, I am coding a basic login logic. For testing purposes, I'm calling return NotFound(); when the post parameters are missing. This

问题 I'm trying to create a common complex object for my models (action parameters) and reuse it in many places. Here is some sample code: [HttpGet("/api/values")] public ActionResult<string> Get([FromQuery] MyModel model) { var sb = new StringBuilder(); sb.AppendLine(model.Id); sb.AppendLine($"{model.Id}-{model.Generated?.DateStart}-{model.Generated?.DateEnd}"); sb.AppendLine($"{model.Id}-{model.Reference?.DateStart}-{model.Reference?.DateEnd}"); return sb.ToString(); } public class MyModel {

问题 I am converting code that was written in ASP.NET MVC to ASP.NET Core MVC. While I was converting the code, I encountered a problem. We used a method that has multiple parameters like this: [HttpPost] public class Search(List<int> ids, SearchEntity searchEntity) { //ASP.NET MVC } But when coding this in .NET Core, the ids parameter is null . [HttpPost] public class Search([FromBody]List<int> ids,[FromBody]SearchEntity searchEntity) { //ASP.NET Core MVC } When I place the ids parameter in the
