                        using (SPSite site = new SPSite("SiteUrl"))

                        {

                            SPServiceContext context = SPServiceContext.GetContext(site);

                            UserProfileManager allProfiles = new UserProfileManager(context);

                            string loginName = @"DomainName\AccountName";
                            //Ex: TestDoamin\abc
                            //You can also use UserExists method to check

                            if (allProfiles.ResolveProfile(loginName).Length == 1)

                            {

                                UserProfile up = allProfiles.GetUserProfile(loginName);

                           

                             }
