c# - ASP.NET MVC5 标识 : Avoid changing logged-in user after registration

Question

我想更改 MVC5 ASP.NET 应用程序的默认注册操作。我的场景是这样的，授权用户(例如管理员)将登录并可以创建新用户。但是使用下面的代码片段，在创建用户后，当前登录的用户将更改为注册用户。

如何更改以下代码以避免更改登录用户？

// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser() { UserName = model.UserName,Name=model.Name };
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            await SignInAsync(user, isPersistent: false);
            return RedirectToAction("Index", "Home");
        }
        else
        {
            AddErrors(result);
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

只需这样做:

if (result.Succeeded)
{
    if (!User.IsAuthenticated)  // if they're already logged in, don't log in again
        await SignInAsync(user, isPersistent: false);
    return RedirectToAction("Index", "Home");
}
