How to Convert var to string? In my windowsphone application page, i want to convert this var DemoHeader to a string.

XDocument myData = XDocument.Load("aarti.xml");

var DemoHeader = from query in myData.Descendants("bookinfo")
                 select new HeaderT
                 {
                     Header = (string)query.Element("header")
                 };


ContentHeaderLine.Text = DemoHeader.ToString();‏ //LINE GIVING WRONG DATA

public class HeaderT
{
    string header;
    public string Header
    {
        get { return header; }
        set { header = value; }
    }

First, var is not a type by itself, the type will be inferred from the value by the compiler. Your type is actually HeaderT and your query returns an IEnumerable<HeaderT> (so possibly multiple).

Presuming you want the first header:

HeaderT first = DemoHeader.First();
string firstHeader = first.Header();

or you want all returned separated by comma:

string allHeaders = String.Join(",", DemoHeader.Select(dh => dh.Header()));

If you want that ToString returns something meaningful(instead of name of the type), override it:

public class HeaderT
{
    private string header;
    public string Header
    {
        get { return header; }
        set { header = value; }
    }

    public override string ToString()
    {
        return Header;
    }
}

Override ToString() in HeaderT class could help. After that, you DemoHeader variable is a list of HeaderT not a single HeaderT.
