XML output to text file?

I'm trying to output a specific node to output to a text file(output to console fine) but I keep getting an error message: 'System.Xml.XmlNodeList' to 'string[]' on this line:

string[] lines = elemList;

Here is some more code:

namespace countC
{
    class Program
    {
        static void Main(string[] args)
        {
            XmlDocument doc = new XmlDocument();
            doc.Load("list.xml");

            XmlElement root = doc.DocumentElement;
            XmlNodeList elemList = root.GetElementsByTagName("version");
            for (int i = 0; i < elemList.Count; i++)
            {
                Console.WriteLine(elemList[i].InnerXml);
                string[] lines = elemList;
                System.IO.File.WriteAllLines(@"C:\VBtest\STIGapp.txt", lines);
            }
            Console.ReadKey();
        } 
    }
}

The error is because you are trying to assign an object of type XmlNodeList to a variable of type string[] - the two are incompatible and you can't assign one from the other.

If you do this instead then it will at least compile:

string line = elemList[i].InnerXml;
System.IO.File.WriteAllText(@"C:\VBtest\STIGapp.txt", line);

Although I'm not sure that it will do what you want (if elemList contains more that one element the above will keep overwriting the given file).

elemList is an XmlNodeList, you can't implicitly cast it to a string array.

You could try this

string line = elemList[i].InnerText;
System.IO.File.WriteAllLines(@"C:\VBtest\STIGapp.txt", line);

but this of course, depends on your data.
