How to select a specific node with LINQ-to-XML

Question

I can select the first customer node and change its company name with the code below.

But how do I select customer node where ID=2?

    XDocument xml         


        

Answer 1

I'd use something like:

dim customer = (from c in xmldoc...<Customer> 
                where c.<ID>.Value=22 
                select c).SingleOrDefault 

Edit:

missed the c# tag, sorry......the example is in VB.NET

Answer 2

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.
