Http Post Web Service

[=?Utf-8?B?cGhlbmdsYWk=?=]

I am not sure really how to explain this but here goes.

I am creating some new web services and I want to be able to post data like
the following:

<Data>
<some value>1</some value>
<more info>2</more info>
</Data>

I have the object built and I can call the web service but all I get in
return is "ERROR". My webservice looks like this:

[WebMethod]
public string GeneratePDFBOL(BillInfo bi)
{
try
{
return bi.BillNumber;
}
catch(Exception e)
{
return e.Message;
}
}

If I take out the BillInfo and add a string value in there, I can post data
but when I try to pass complex data, it does not work.I have searched all
over and I can not find anything on how to do this. It seems to work for Soap
but I want to have unified calls for both SOAP and HTTP-POST.

Can someone point me in the right direction?

Hi,
As per my uderstanding HTTP-GET or HTTP-POST supports only native data
types(primitive data types).Only SOAP allows the client to pass objects as
parameters.

However, SOAP toolkits exist for most programming languages, including Java
and COM-based Microsoft programming languages such as Visual C++ and Visual
Basic. You'll almost always use SOAP encoding with your XML Web services, for
the following reasons:
Only SOAP allows the client to pass objects as parameters. In other words,
the current version of the UpdateCustomers method wouldn't work over HTTP GET
or HTTP POST because it requires a CustomerDetails object as a parameter.
SOAP also provides support for ByRef parameters.

SOAP is more standardized. .NET defines its own rules for encoding
information in an HTTP GET or HTTP POST message.

SOAP provides better exception support with .NET clients. If a method called
over HTTP GET or if HTTP POST fails, it just returns an unhelpful HTTP error.
