How To Get All User Profile Properties And Get Difference between User Hire Date And Current Date?

i have class UserProperties.cs in that i write some code=> public UserProperties(SPUser currentUser) { using (var site = new SPSite(SPContext.Current.Web.Url)) { try { LoadUserProperties(site, currentUser); } catch (Exception exp) { LoggingService.LogError("Failed to get " + currentUser.Name + "'s information", exp); } } }

private void LoadUserProperties(SPSite site, SPUser user) { CurrentUser = user; var userLoginName = CurrentUser.LoginName;

        SPServiceContext serviceContext = SPServiceContext.GetContext(site);
        var profileManager = new UserProfileManager(serviceContext);

        var userProfile = profileManager.GetUserProfile(userLoginName);

        Profile = userProfile;
        //object value
      var  currentuserHireDate = userProfile[PropertyConstants.HireDate].Value != null
            ? userProfile[PropertyConstants.HireDate].Value.ToString()
            : "";

        CurrentJobFunction = userProfile[PropertyConstants.Department].Value != null
            ? userProfile[PropertyConstants.Department].Value.ToString()
            : "";

        CurrentJobFunctionUrl = GetJobFunctionUrl(CurrentJobFunction);

        CurrentLocation = userProfile[PropertyConstants.Office].Value != null
            ? userProfile[PropertyConstants.Office].Value.ToString()
            : "";

        CurrentLocationUrl = GetLocationUrl(CurrentLocation);

        PrefferedName = userProfile[PropertyConstants.PreferredName].Value != null
            ? userProfile[PropertyConstants.PreferredName].Value.ToString()
            : "";

        ProfilePicture = userProfile[PropertyConstants.PictureUrl].Value != null &&
                         !userProfile[PropertyConstants.PictureUrl].Value.ToString().Equals(string.Empty)
            ? userProfile[PropertyConstants.PictureUrl].Value.ToString()
            : "/_layouts/15/images/PersonPlaceholder.200x150x32.png";

        MyProfileUrl = userProfile.PersonalSite != null ? userProfile.PersonalSite.Url : "#";

        if (userProfile[PropertyConstants.PreferredName].Value != null)
        {
            FirstName = userProfile[PropertyConstants.FirstName].Value != null &&
                        !userProfile[PropertyConstants.FirstName].Value.ToString().Equals(string.Empty)
                ? userProfile[PropertyConstants.FirstName].Value.ToString()
                : userProfile[PropertyConstants.PreferredName].Value.ToString();

            LastName = userProfile[PropertyConstants.LastName].Value != null &&
                       !userProfile[PropertyConstants.LastName].Value.ToString().Equals(string.Empty)
                ? userProfile[PropertyConstants.LastName].Value.ToString()
                : string.Empty;
        }
    }

//I have NewHire webparts in NewHire.cs i write some code to test can i access all user properties ->

private HtmlGenericControl GetHtmlForNewHires() { var userproperties = new UserProperties();

        var url = userproperties.MyProfileUrl;
        if (string.IsNullOrEmpty(url))
            url = "#";
        var s = userproperties.FirstName;
        var article = new HtmlGenericControl("article");

        article.InnerHtml = s;

}

//But i am not getting user properties i have 5 user profiles. and also also i want to get user having hire date is within last 30 days
