ASP.NET Core equivalent of ASP.NET MVC 5's HttpException

ASP.NET Core equivalent of ASP.NET MVC 5's HttpException

In ASP.NET Core, the equivalent of HttpException from ASP.NET MVC 5 is the HttpException class from the Microsoft.AspNetCore.Http.Exceptions namespace. This class represents an HTTP exception that can be thrown by middleware components or controllers to return an HTTP error response to the client.

Here's an example of how you can use HttpException in an ASP.NET Core controller to return a 404 Not Found response:

using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Mvc.Filters; // ... public class MyController : Controller { public IActionResult MyAction() { // Check if some condition is not met if (someConditionIsNotMet) { throw new HttpException(StatusCodes.Status404NotFound); } // ... } }

In this example, we create a new HttpException with the StatusCodes.Status404NotFound status code and throw it from our action method. This will result in a 404 Not Found response being returned to the client.

Note that HttpException is just one of many exception types that can be used to return HTTP error responses in ASP.NET Core. Other options include HttpException's parent class Exception, the StatusCodePagesMiddleware, and the ProblemDetails class. The choice of which option to use depends on the specific requirements of your application.
