[Q] SoapFormatter.Deserialize gives exception

Pranav Mundi

Hi,
I am using SoapFormatter.Deserialize method for
deserializing a Soap message to get the SoapMessage object.

The code gives me the following exception:
----------------------------------------------
An unhandled exception of
type 'System.Runtime.Serialization.SerializationException'
occurred in
system.runtime.serialization.formatters.soap.dll

Additional information: Parse Error, no assembly
associated with Xml key tns ProfileInfoHeader
----------------------------------------------

Following is the code I am trying to execute:



public static void StreamToSOAPMessage()
{
Console.WriteLine
("SOAPStreamToSOAPMessage\n");

SoapFormatter formatter = new
SoapFormatter();
MemoryStream stream = new
MemoryStream();

StreamWriter tw = new StreamWriter
(stream);


tw.Write("<?xml version=\"1.0\"
encoding=\"utf-8\"?><soap:Envelope
xmlns:xsi=\"http://www.w3.org/2001/XMLSchem...\"
xmlns:xsd=\"http://www.w3.org/2001...\"
xmlns:soapenc=\"http://schemas.xmlsoap.org/soap...

<ProfileName

</tns:ProfileInfoHeader> </soap:Header> <soap:Body

ng/\"> <tns:AddNumbers

</tns:AddNumbers> <soapenc:Array id=\"id1\"
soapenc:arrayType=\"xsd:int[2]
\"><Item>int</Item><Item>int</Item></soapenc:Array></soap:B
ody></soap:Envelope>");
tw.Flush();
stream.Position = 0;

SoapMessage soapMessage = new
SoapMessage();
formatter.TopObject = soapMessage;

HeaderHandler headerHandler = new
HeaderHandler(ParseHeaders);

soapMessage = (SoapMessage)
formatter.Deserialize(stream);

String xmlNameSpace =
soapMessage.XmlNameSpace;
Console.WriteLine("XmlNameSpace "+
xmlNameSpace);

String methodName =
soapMessage.MethodName;
Console.WriteLine
("methodName "+methodName);

Object[] parameters =
soapMessage.ParamValues;

int[] nIDs = (int[]) parameters[1];

for (int i=0; i<parameters.Length;
i++)
Console.WriteLine
("param "+i+" "+parameters[i].GetType());

Console.WriteLine("\n");
}


--------------------------------------------------------
The Soap message was for the web service whose code is
given below:
