Hi there,

Could you please be a bit more specific as to what you are attempting
to achieve? Are you connecting to a specific source? If so please
provide the appropriate details.

Also, are you looking for sample code or more of a tutorial that will
show how to do this?

Hi answerguru-ga,
I want to send aspx page1 that sends data in XML format such as
<UserId>User1</UserId> to another aspx page2 (in the format text/xml).
I want a sample that I can use to both send and receive data.

I know that using classic asp (not .net) we could use MSXML but that
does not seem to be possible here.

A working sample would be great.
Thanks
Krishnan

Not Web services 

No I am not using web services, I want to send and receive informaiton
in pure XML format (not using a file either). What works in classic
XML does not work here.

Thanks

Hi, nk412-ga:

I think you are asking how to request XML data using an HTTP REQUEST
in ASPX, using C# as needed to process the returned information.

Of course you might be equally interested in how to respond, at the
other end of the "connection" to such a request.

Is this the gist of your question?

regards, mathtalk-ga

Are you using web services?  Are these pages in the same web or
different?  Can you utilize web services, or do you need to send the
data during a redirect?

Not using web services, just transfer using XML Request/response

Well, to generate some XML, use the System.Xml namespace. E.G.:

using System.Xml;

[...]

public string GetUserXml(string userName)
{
    XmlDocument doc=new XmlDocument();
    XmlElement userId=doc.CreateElement("UserId");
    userId.InnerText=userName;
    doc.AppendChild(userId);
    return doc.OuterXml;
}

The call GetUserXml("User1") will generate and return the XML string
"<UserId>User1</UserId>". Just modify the method as you see fit, and
use a WebRequest to send the data out...
