Validate Xml from Serialized Web Service Proxy Class throws on soap Array

[Joris van Lier]

Hi, im trying to validate objects before they are sent over the wire to a
webservice,
the schema embedded into WSDL is not sufficient so i took that schema and
extended it with additional restrictions,
after conversion from local domain class into remote domain class the remote
class (generated from WSDL) is serialized to XML and validated using the
schema, this throws "Undefined complexType
http://schemas.xmlsoap.org/soap/encoding/:Array is used as restriction of
complex type" (translated)

How do i add this schema or map the soap array to another type?

private void ValidateRemoteDomainObject(remote.webservice.entity o)
{
MemoryStream ms = new MemoryStream();
XmlSerializer xs = new XmlSerializer(o.GetType());
xs.Serialize(ms, o);
ms.Position = 0;
ValidateXmlSchema(new StreamReader(ms), "Schema.xsd");
}

void ValidateXmlSchema(TextReader reader, string schemaUri)
{
XmlReaderSettings xrs = new XmlReaderSettings();
xrs.ValidationType = ValidationType.Schema;
xrs.ValidationFlags &=
~XmlSchemaValidationFlags.AllowXmlAttributes;
xrs.ValidationFlags |=
XmlSchemaValidationFlags.ReportValidationWarnings;
xrs.ValidationEventHandler += new
ValidationEventHandler(ValidationEventHandler);
XmlSchema schema = XmlSchema.Read(
XmlReader.Create(schemaUri), this.ValidationEventHandler);
xrs.Schemas.Add(schema);
XmlReader xr = XmlReader.Create(reader, xrs);
while(xr.Read()){
// do something with node
}
}

void ValidationEventHandler(object sender, ValidationEventArgs e)
{
throw new ApplicationException(
String.Format("{0}", new object[] {e.Message}),
e.Exception
);
}

You need a schema for the namespace
http://schemas.xmlsoap.org/soap/encoding/ that defines the Array type. I
am not sure whether the various soap specifications define a schema,
perhaps someone in microsoft.public.dotnet.framework.aspnet.webservices
knows more.
