After upgrading to .Net 6, system.web no longer contains HttpException

Question

In old versions of .Net Core, I could do this to throw an exception:

public class MyParentController : Microsoft.AspNetCore.Mvc.Controller
{
    protected virtual GamePlayer CurrentPlayer => Players.GetPlayer(Session) ?? throw MyCustomHttpException(HttpStatusCode.Unauthorized, "Unauthorized");

    protected Exception MyCustomHttpException(HttpStatusCode code, String msg) => throw new System.Web.HttpException(code.ToString(), Int32.Parse(msg));
}

But after upgrading my solution to .Net 6, I am getting this error:

The type or namespace name HttpException does not exist in System.Web

Does new .Net not offer anything like this?

Thanks!

In your case you should do:

public class MyParentController : Microsoft.AspNetCore.Mvc.Controller
{
    [HttpGet("CurrentPlayer")]
    public IActionResult GetCurrentPlayer() 
    {
        var player = Players.GetPlayer(Session);
        return player != null ? Json(player) : Unauthorized();
    }
}

HttpException Class just exist in .net framework ,I suppose your project was an ASP.Net project?

https://docs.microsoft.com/en-us/dotnet/api/system.web.httpexception?view=netframework-4.8

To Handle error in .net 6.0,I think you could read the document:

https://docs.microsoft.com/en-us/aspnet/core/fundamentals/error-handling?view=aspnetcore-6.0

After upgrading to .Net 6, system.web no longer contains HttpException
