Hallo...

I'm working with some complex coding. But I'm stuck at a very simple if statement:

    string hotelNodeString = "";
    foreach(var season in Model.Children.Where("Visible"))
    {
      hotelNodeString = hotelNodeString + season.seasonHotels;
      if(!season.IsLast())
      {
       hotelNodeString = hotelNodeString + ",";
      }
    }
    string[] accommodationHotels = hotelNodeString.Split(',');
     
    string shipNodeString = "";
    foreach(var season in Model.Children.Where("Visible"))
    {
     if(season.HasValue("seasonShips"))
     {
      shipNodeString = shipNodeString + season.seasonShips;
      if(!season.IsLast())
      {
       shipNodeString = shipNodeString + ",";
      }
     }
    }
    string[] accommodationShips = shipNodeString.Split(',');
    
    List<string> accommodations = new List<string>();
    foreach(string st in accommodationShips)
    {
     if (!accommodations.Contains(st))
     {
      accommodations.Add(st);
     }
    }
    foreach(string st in accommodationHotels)
    {
     if (!accommodations.Contains(st))
     {
      accommodations.Add(st);
     }
    }

For some reason the first foreach loop output a comma.

I need to check if the seasonHotels has a value. If not the loop shoudn't add anything.

I have tried to do this:

    foreach(var season in Model.Children.Where("Visible"))
    {
     if(season.HasValue("seasonHotel"))
     {
      hotelNodeString = hotelNodeString + season.seasonHotels;
      if(!season.IsLast())
      {
       hotelNodeString = hotelNodeString + ",";
      }
     }
    }

But it is the same result. All ideas is appreciated.
