Why is the return value not XmlDocument ?

[Shailendra Batham]

hi gurus

I have a asp.net web services and in that i have a function which returns XmlDocument as the return value, when I test the service it works fine and I can see the XML.

When I try to call the XML from asp.net, it does not return XmlDocument and gives me this message

Cannot implicitly convert type 'System.Xml.XmlNode' to 'System.Xml.XmlDocument'

This is my code
XmlDocument xd = new XmlDocument();
xd = sdws.CreateSurvey(ValidXMLFile);

Am I missing something ?

thanks,
shailendra batham

We need to see the code that defines what "sdws.CreateSurvey(ValidXMLFile) is.

The error message indicates that you are trying to use an XML node (a piece of an XML document) in a place where an actual XMLDocument is required.

XmlDocument implements XmlNode, which is abstract class. If
CreateSurvey() method does return XmlDocument, but as XmlNode, you nedd
only to cast it explicitly:

XmlDocument xd = (XmlDocument)sdws.CreateSurvey(ValidXMLFile);
