Webservice returns void

[Pramod]

Hi,

I have a web service that returns void but internally writes data to
context as shown below:

------------------------------------------------------------------------------------------------------------------------------------------------------
[WebMethod( Description = "Gets the configuration" )]
public void GetChanges( string guid )
{
try
{
string configData = "<test></test>";
byte[] utf8 = Encoding.UTF8.GetBytes( configData );

Context.Response.ContentType = "text/xml";
Context.Response.BinaryWrite( utf8 );
Context.Response.Flush();
}
catch( Exception ex )
{
}
}
------------------------------------------------------------------------------------------------------------------------------------------------------

Now when I utilize this method in my C# code, I get following error:
Response is not well-formed XML.
------------------------------------------------------------------------------------------------------------------------------------------------------
localhost.WebServiceTest asrv = new
TestMSWebService.localhost.WebServiceTest();
asrv.GetChanges("DF61B16D-61AB-4644-91BB-0F0441D6AB43");
------------------------------------------------------------------------------------------------------------------------------------------------------

How do I get the response from the webservice?

Please let me know.

Thanks in advance,
PSI

if you want to return binary data, would not something other than a
web service be better? possibly an aspx or ashx page that does the
binary write to the return stream?

or if you don't need a binary write (because your test data is in fact
just text) why not return a string from the web service and deal with
that at the other end?

Sorry to say but we cannot change the Webservice....

hmm... ok well you could try executing the web service directly rather
then consuming it. when you consume it it gets all error checked and
such, but if you try calling it (never tried myself, just thinking)
maybe through webclient? you could get the response stream from that?
just a thought, not sure how to do it but sure it can be done.

cheers,

Sounds to me like you are getting back a Content, sure, but the .NET method
that catches it doesn't accept it as XML.
Can you see your output anywhere?

Well-formed XML would also have the string
<?xml version="1.0"?>
at minimum. Try creating a new XML file in Visual Studio and see what I
mean.
It creates a "blank" file with the following line ( Visual Studio 2005 ):
<?xml version="1.0" encoding="utf-8"?>
I am not familiar with the Context class, but it appears to let you
construct your own HTTP response, sending a Content-Type: HTTP Header
followed by the content. Your proxy class then is looking for XML, and I
would bet it's strict on accepting only XML with proper headers as such.

Hope this helps, try changing to:

string xmlHeader = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
string configData = "<test></test>";
byte[] utf8 = Encoding.UTF8.GetBytes( xmlHeader + configData );

localhost.WebServiceTest asrv = new
TestMSWebService.localhost.WebServiceTest();
asrv.GetChanges("DF61B16D-61AB-4644-91BB-0F0441D6AB43");
