C# - Exporting listbox contents to XML

Question

I have a list box control that contains key value pairs delimited by an "=" sign.

Example:

hot=cold

fast=slow

high=low

blue=red

I also have a button that will allow user to export this list in XML. How could I easily do that?

How do I crat the XML file what format should it be in?

Answer 1

You can use LINQ:

var xml = new XElement("Items",
    from s in strings 
    let parts = s.Split('=')
    select new XElement("Item", 
        new XAttribute("Key", parts[0]), 
        parts[1]
    )
);
