ASP.NET MVC 6 handling errors based on HTTP status code

Question

I want to display different error messages for each status code e.g:

• 400 Bad Request
• 403 Forbidden
• 500 Internal Server Error
• 404 Not Fou

Answer 1

Works with various status codes without specifying each one individually in the controller.

Startup.cs:

public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
{
    app.UseStatusCodePagesWithRedirects("/StatusCodes?statusCode={0}");
    app.UseMvcWithDefaultRoute();

Controller:

  public class StatusCodesController : Controller
  {
    public IActionResult Index(string statusCode)
    {
      if(statusCode == null) statusCode = "";
      if(statusCode == "404") return View("Error404");
      return View("Index",statusCode);
    }

    public IActionResult Test404() { return StatusCode(404); }
    public IActionResult Test500() { return StatusCode(500); }

View:

@model string
@{ ViewData["Title"] = Model + " Oops!"; }




  

    

      

        
Oops!
        
@Model Error
        
Sorry, an error has occurred!
