I'm using LINQ together with XDocument to read a XML File. This is the code:
XDocument xml = XDocument.Load(filename);
var q = from b in xml.Descendants("product")
select new
{
name =b.Element("name").Value,
price =b.Element("price").Value,
extra =b.Element("extra1").Value,
deeplink =b.Element("deepLink").Value
};
Now the problem is, the extra1 field is not always present. There are items in the XML file without that node. If that happens it's crashing with a NullReferenceException.
Is there any possibility to include a "check if null" so I can prevent it from crashing?
Use (string) instead of .Value:
var q = from b in xml.Descendants("product")select new
{
name =(string)b.Element("name"),
price =(double?)b.Element("price"),
extra =(string)b.Element("extra1"),
deeplink =(string)b.Element("deepLink")
};
