Question

I am working with a method using LINQ to XML to return a string.This is the XML

       <data name="lnkViewResultResource1.Text" xml:space="preserve">
    <value>View results</value>
  </data>
  <data name="lnkVoteResource1.Text" xml:space="preserve">
    <value>Vote</value>
  </data>
  <data name="number of results" xml:space="preserve">
    <value>You already {0} voted in this poll {1}</value>
  </data>

(I want to take the “name” attribute)
This is my method:

    Public Shared Function getlabel(ByVal filename As String, ByVal valuetrans As String) As String
    Dim label = From l In XElement.Load(filename).Elements("data") Where l.Element("value").Value = valuetrans Select (l.Attribute("name").Value).First
    Return label.ToString
End Function

And this is returning this :

System.Linq.Enumerable+WhereSelectEnumerableIterator`2[System.Xml.Linq.XElement,System.String]

I googled and used following this link FirstOrDefault(), but it didn’t work in my case.
Any ideas?

Thanks in advance,

Alf.

I think your call to ‘First’ is placed wrong, try this:

Dim query = From l In XElement.Load(filename).Elements("data") _ 
     Where l.Element("value").Value = valuetrans _
     Select (l.Attribute("name").Value)
Dim label = query.First()
Return label.ToString()
