How to add XElements dynamically in a loop?

Question

I get an HybridDictionary with all the child XElements.
I don't know ahead how many items I have there.
So instead of doing this:

xmlDoc.Element("Parent").Add(
     new XElement("Child", new XAttribute("Name", "Child1"),
           new XElement("Id", "796"),
           new XElement("Name", "gdsa")
           etc..
      ));  

I'm trying to do something like that:

Strung [] allKeys = new String[ChildElements.Count];
TheHybridDictionary.Keys.CopyTo(allKeys, 0);

xmlDoc.Element("Parent").Add(
      new XElement("Child", new XAttribute("Name", "Child1"),
            for (int i = 0; i < TheHybridDictionary.Count; i++)
                   new XElement(allKeys[i], TheHybridDictionary[allKeys[i]])

But how to connect whatever is inside the for loop to be part of the XML document construction?

Answer 1

Problem is, your HybridDictionary class does not implement IEnumerable, so you can't use LINQ on it directly.

But you can use allKeys string array instead:

string [] allKeys = new String[ChildElements.Count];
TheHybridDictionary.Keys.CopyTo(allKeys, 0);

xmlDoc.Element("Parent").Add(
    new XElement("Child", new XAttribute("Name", "Child1"),
        allKeys.Select(x => new XElement(x, TheHybridDictionary[x])))
