illegal Characters in Xml when sent to XMLreade

[nicklieb]

I am trying to create a listener page, that will validate and incoming XML document with an XSD.

StreamReader InboundStream = new StreamReader(Page.Request.InputStream);
string UseString = InboundStream.ReadToEnd();
InboundStream.Close();

string result = ValidateXML(xmlString);

    public string ValidateXML(string UseString)
    {
        try
        {
            XmlReader xmlrdr = XmlReader.Create(new StringReader(UseString));
            xmlrdr.Settings.ValidationType = ValidationType.Schema;
            xmlrdr.Settings.Schemas.Add(null, "Schemas\ttc1.xsd");
            xmlrdr.Settings.ValidationEventHandler += new ValidationEventHandler(ValidationHandler);
           
            while (xmlrdr.Read()) ;
            return "Validated";
        }
        catch (Exception ex)
        {
            return ex.Message + "<br>" + ErrorsCount + "<br>" + ErrorMessage;
        }          
    }

When it hits XMLReader.Create is bombs out with the illegal character, but gives no indication where it is.

Has anyone had experience of create a listener and validating against a schema? This is using .NET 2.0 which differs slightly from 1.1 where you have to setup the XMLValidator class. in 2.0 you can lump everything intogether.. ( or so i keep reading!!)

thanks in advance

If you are having a string 'UseString' and XmlReader.Create (String). Then use it directly as:
XmlReader xmlrdr = XmlReader.Create(UseString);

Sharing the best from my side...
