Question

I will be passing the xml file like this:

File1.PostedFile.InputStream 

//reading xml file.....
public static void readXMLOutput(Stream stream)
{

    System.Xml.Linq.XDocument xml = System.Xml.Linq.XDocument.Load(stream);

    var query = from p in xml.Element("ste").Element("Application")
                //where (int)p.Element("Id") == 1
                select Page;

    foreach (var record in query)
    {
        Response.Write("dfe") + record.Element("dfe").Value;
    }

error:

Error 1 The best overloaded method match for ‘System.Xml.Linq.XDocument.Load(string)’ has some invalid arguments

cannot convert from ‘System.IO.Stream’ to ‘string’

Answer 1

Are you using .NET 3.5 by any chance? XDocument.Load(Stream) apparently only arrived in .NET 4.

You might want to use the overload which takes an XmlReader (which is supported in 3.5).

EDIT: Sample code:

static XDocument LoadFromStream(Stream stream)
{
    using (XmlReader reader = XmlReader.Create(stream))
    {
        return XDocument.Load(reader);    
    }
}
