c# - 在 Controller 中获取 ApplicationUser

Question

我正在谷歌搜索以在 ASP.NET Identity 3.0 的 Controller 中获取应用程序用户，但我只找到 5 及以下的结果。

我正在尝试获取 ApplicationUser 属性，但我根本无法获取 ApplicationUser。我想这很容易，因为我是唯一遇到这个问题的人。

using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNet.Mvc;
using Microsoft.AspNet.Mvc.Rendering;
using Microsoft.Data.Entity;
using System;
using System.Collections.Generic;
using System.Reflection;
using Microsoft.AspNet.Identity;
using System.Security.Claims;

namespace ApplicationUserFMLTest.Controllers
{
    public class CustomClassController : Controller
    {
        private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signInManager;

        private ApplicationDbContext _context;

        public CandidatesController(ApplicationDbContext context, UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager)
        {
            _context = context;
            _userManager = userManager;
            _signInManager = signInManager;
        }

        // GET: CustomClass
        public async Task<IActionResult> Index()
        {
            ApplicationUser currentUser = _userManager.FindByIdAsync(User.Identity.GetUserId()).Result;


            if (currentUser.PropBool)
                return View(currentUser);


            return View();
        }

        // ManageController function
        private async Task<ApplicationUser> GetCurrentUserAsync()
        {
            return await _userManager.FindByIdAsync(HttpContext.User.GetUserId());
        }

    }
}

Joe 的回答会很好，但请注意还有一个更简单的方法，它直接采用 ClaimsPrincipal 实例并在内部调用 GetUserId:

var user = await _userManager.GetUserAsync(User);
