<pre><code>var userId = this.User.FindFirstValue(ClaimTypes.NameIdentifier);

or

<pre><code>var userId = HttpContext.User.FindFirstValue(ClaimTypes.NameIdentifier);

As stated somewhere in this post, the GetUserId() method has been moved to the UserManager.

<pre><code>private readonly UserManager&lt;ApplicationUser&gt; _userManager;

public YourController(UserManager&lt;ApplicationUser&gt; userManager)

 _userManager = userManager;
}

public IActionResult MyAction()
{
 var userId = _userManager.GetUserId(HttpContext.User);

 var model = GetSomeModelByUserId(userId);

If you started an empty project you might need to add the UserManger to your services in startup.cs. Otherwise this should already be the case.

In .net core 3.1 (and other more recent versions), you can use:
<pre><code>private readonly UserManager&lt;IdentityUser&gt; _userManager;

public ExampleController(UserManager&lt;IdentityUser&gt; userManager)
{
 _userManager = userManager;

Then:
<pre><code>string userId = _userManager.GetUserId(User);

Or async:
<pre><code>var user = await _userManager.GetUserAsync(User);
var userId = user.Id;

At this point, I'm trying to figure out why you'd use one over the other. I know the general benefits of async, but see both of these used frequently. Please post some comments if anyone knows.

As an administrator working on other people's profile and you need to get the Id of the profile you are working on, you can use a ViewBag to capture the Id e.g ViewBag.UserId = userId; while userId is the string Parameter of the method you are working on.

<pre><code> [HttpGet]

 public async Task&lt;IActionResult&gt; ManageUserRoles(string userId)
 {

 ViewBag.UserId = userId;


 var user = await userManager.FindByIdAsync(userId);

 if (user == null)
 {
 ViewBag.ErrorMessage = $"User with Id = {userId} cannot be found";
 return View("NotFound");
 }

 var model = new List&lt;UserRolesViewModel&gt;();

 foreach (var role in roleManager.Roles)
 {
 var userRolesViewModel = new UserRolesViewModel
 {
 RoleId = role.Id,
 RoleName = role.Name
 };

 if (await userManager.IsInRoleAsync(user, role.Name))

 userRolesViewModel.IsSelected = true;

You need to add <code>using</code> statement because <code>GetUserId()</code> won't be there without it.

I've done this before with MVC5 using <code>User.Identity.GetUserId()</code> but that doesn't seem to work here.
The <code>User.Identity</code> doesn't have the <code>GetUserId()</code> method.
I am using <code>Microsoft.AspNet.Identity</code>.

我以前使用User.Identity.GetUserId()在MVC5中这样做过，但在这里似乎不起作用。User.Identity没有GetUserId()方法。我正在使用Microsoft.AspNet.Identity。
