How to return JsonResult with HTTP Status Code 500 from Razor Page?

Question

In my ASP.NET Core Razor Pages application, I sometimes send requests to the server via ajax.

In those cases, I want to return JsonResult either for success or for error.

But I can't find a way to change HTTP Status Code for JsonResult.

Here's my method:

public IActionResult OnPostFileUpload()
{
   try
   {
       // code to manage and save the file, this request is AJAX
       return new JsonResult("done");
   }
   catch (Exception ex)
   {
       return new JsonResult(message); // how should I set it to be 500?
   }
}

Set .StatusCode on the JsonResult object?

You can assign the StatusCode to JsonResult as below:

using System.Net;

return new JsonResult(message)
{
    StatusCode = (int)HttpStatusCode.InternalServerError
};
