Question

I’m trying to get multiple descendants and give these values to some properties in a class. The part I cannot figure out is how can I figure out between the descendants:

var elements =
  from descendant in doc.Descendants().Where(desc => 
    desc.Name == "Name1" || desc.Name == "Name2" ||  desc.Name == "Name3")
  select new AppInfo.Names 
  {
    Name1 = //here I want to get the Name1 descendant .Value
    Name2 = //here I want to get the Name2 descendant .Value
    Name3 = //here I want to get the Name3 descendant .Value
  };

Is it possible to do it like this? Or do I have to do a new iteration through the elements?

Answer 1

If AppInfo.Names is simply an array of names, try this:

var filterNames = new []{"Name1", "Name2", "Name3"};
var elements = from descendant in doc.Descendants()
                   .Where(desc =>filterNames.Contains(desc.Name))
                    select descendant.Value;
AppInfo.Names = elements.ToArray();

EDIT:

In the case of Names being properties, you could use something like:

var names = AppInfo.Names
{
   Name1 = doc.Descendants("Name1").First().Value,
   Name2 = doc.Descendants("Name2").First().Value,
   Name3 = doc.Descendants("Name3").First().Value
}
