状态码 406 使用 ASP.NET 内核中的格式响应数据 Web API

Question

I'm trying to format the response from a GET method i followed the Microsoft tutorial.I can get json response but not xml it returns a status code 406.

This is my Startup class:

services.AddControllers()
            .AddXmlSerializerFormatters();
        services.AddControllers()
            .AddNewtonsoftJson();
        services.AddControllers().AddNewtonsoftJson(options =>
        {
            // Use the default property (Pascal) casing
            options.SerializerSettings.ContractResolver = new DefaultContractResolver();

        });
        services.AddControllers(options =>
        {
            // requires using Microsoft.AspNetCore.Mvc.Formatters;
            options.OutputFormatters.RemoveType<StringOutputFormatter>();
            options.OutputFormatters.RemoveType<HttpNoContentOutputFormatter>();
        });

Controller:

[Route("api/[controller]")]
[ApiController]
[FormatFilter]
public class TableController : ControllerBase
{
[HttpGet("values.{format}")]
    public ActionResult<List<Table>> Get()
    {
        return _context.Table.ToList();
    }
}
