如何获取文件系统路径以在ASPNET MVC中保存文件

我有一个上传文件的控制器

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using System.IO;
using System.Linq;
using System.Collections.Generic;
using System.Threading.Tasks;
using System;
using System.Web;

namespace TodoApi.Controllers {
    [Route("[controller]")]
    public class FileUploadController : Controller
    {

        public FileUploadController()
        {
        }

        [HttpPost]
        public IActionResult Index(List<IFormFile> files)
        {
            var filePath = Server.MapPath("/UploadedFiles/Foo");
            return Ok();
        }
    }
}

当我试图构建它时,它声称上下文中没有服务器。我试过了 HttpContext.Current.Server System.Web.HttpContext.Current.Server 但我总是在上下文中找不到X。我错过了什么?

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>


</Project>

这是当前的错误
