是否可以从默认表AspNetUsers中删除行？如果是，请解释。

我能删除具有AspNetUsers Fk的记录。

公共ActionResult删除（STUDENT st）
        {
                var studentuser = st.user;
                st.user = null;
                db.Entry（st）.State = EntityState.Deleted;
                db.SaveChanges（）; //从db中成功删除
                var userid = User.Identity.GetUserId（）;
                var user = _userManager.FindById（userid）;
                _userManager.DeleteAsync（用户）;
            return RedirectToAction（＆＃34; Index＆＃34;，＆＃34; Admin＆＃34;）;
        }

这是我之前用来删除用户的代码段

// Find the user
var user = await _userManager.FindByIdAsync(id);
var logins = user.Logins;

// Delete every login, if he has
foreach (var login in logins.ToList())
{
  await _userManager.RemoveLoginAsync(login.UserId, new UserLoginInfo(login.LoginProvider, login.ProviderKey));
}

// Delete every role, if he has
var rolesForUser = await _userManager.GetRolesAsync(id);
if (rolesForUser.Count() > 0)
{
    foreach (var item in rolesForUser.ToList())
    {
       // item should be the name of the role
       var result = await _userManager.RemoveFromRoleAsync(user.Id, item);
    }
}

// Delete the user itself
_await _userManager.DeleteAsync(user);

是的，确实如此。但首先，您必须在删除之前从用户中删除所有现有角色。

示例：Roles.RemoveUserFromRoles("userName",Roles.GetRolesForUser("userName"));
