This C# code produces the xml that is provided under it. But I can not get the string iconcode1 to work. The string iconcode1 line throws the following error.
Object reference not set to an instance of an object
I am trying to grab every other iconCode which is the daytime iconcode for the image i need for the forecast. I want to loop through grab the icon code format it and insert it into the xml like i have attempted below.
If you have any other ways to do this I would appreciate the help!
XDocument xFore;
if (createFile2)
{
string forecastUrl = "http://ift.tt/Wx8KjF" + lat + "," + lon + "&locationtype=latitudelongitude&units=english&cultureinfo=en-en>&verbose=true&access_token=" + token;
var source = client.DownloadString(forecastUrl);
JObject jo = JObject.Parse(source);
XNode xNode = JsonConvert.DeserializeXNode(jo.ToString(), "forecast");
xFore = XDocument.Parse(xNode.ToString());
Int32 result1;
string iconcode1 = xFore.Root.Element("dailyForecastPeriods/iconCode").Value;
Int32.TryParse(iconcode1, out result1);
string iconFilename2 = "cond" + string.Format("{0:00#}", result1) + ".png";
DayOfWeek day = DateTime.Now.DayOfWeek;
DayOfWeek day1 = (DayOfWeek)((byte)(day + 1) % 7);
DayOfWeek day2 = (DayOfWeek)((byte)(day1 + 1) % 7);
DayOfWeek day3 = (DayOfWeek)((byte)(day2 + 1) % 7);
DayOfWeek day4 = (DayOfWeek)((byte)(day3 + 1) % 7);
DayOfWeek day5 = (DayOfWeek)((byte)(day4 + 1) % 7);
DayOfWeek day6 = (DayOfWeek)((byte)(day5 + 1) % 7);
DayOfWeek day7 = (DayOfWeek)((byte)(day6 + 1) % 7);
xFore.Root.Add(new XElement("day", day),
new XElement("day1", day1),
new XElement("day2", day2),
new XElement("day3", day3),
new XElement("day4", day4),
new XElement("day5", day5),
new XElement("day6", day6),
new XElement("day7", day7),
new XElement("img_small", weatherImages + @"Small/" + iconFilename2),
new XElement("img_large", weatherImages + @"Large/" + iconFilename2));
if (xFore.XPathSelectElement("/error") == null) xFore.Save(foreFilename);
}
else
{
xFore = XDocument.Load(foreFilename);
}
XElement xCurrElem = XElement.Parse(xCurr.Root.ToString());
XElement xForeElem = XElement.Parse(xFore.Root.ToString());
weatherDoc.Root.Add(xCurrElem);
weatherDoc.Root.Add(xForeElem);
