Converting array of objects to XML in C#

Question

I know there's no built in converter to convert an array of objects to XML. Is there a quick rudimentary way to create a XML out of the array to help me do a LINQ to XML join between this one and another XML I have?

Do you mean besides just writing a list of tag/value pairs to a text file? — mbeckish

You may not have to convert the objects to XML; that's not a requirement for doing joins when you use LINQ to XML. You should provide more details, like what type of query you're trying to write and what the class looks like for your objects. — Jacob

You can use Linq to XML, it is really easy to map from your existing data structures to XML, i.e.:

int[] values = { 1, 2, 17, 8 };

XDocument doc = new XDocument();
doc.Add(new XElement("root", values.Select( x=> new XElement("item", x))));

produces the following output:

<root>
  <item>1</item>
  <item>2</item>
  <item>17</item>
  <item>8</item>
</root>

Neat! Is there any way we could do the same for a multidimensional array? For string[,] values

You can always use XmlSerializer to transform a list of C# objects to XML document. The result of the serialization may be customized by using metadata attributes to designate, for example, root nodes or which class property is to be ignored etc... You will definitely need to apply the attributes to make the resulting XML conform as much as possible to your requirements.

Here is a basic tutorial on serializing an Object to XML:
