Hi All -
I am creating a upgrade utility that transfers an bin / exe image over an
xml stream. But I can not seem to get the deserialization of the binary
field to work correctly. What I have is a base 64 encoded field but when I
try to deserialize, I throw an XML / reflection exception. However, if I
remove the base64 (m_Data) stuff everything works fine. I clearly have a
problem with my m_Data set-up. Does anybody know how to do this? What are
the corrrect data type and attributes?
// TEST SML STRING
String* xmlstr = "<?xml
version=\"1.0\"?><VersionMap><Packages><Firmware>< Description>Firmware Ver
1.2.1200</Description><ID>1000</ID><Size>419292</Size><Signature>ver.1.2.1200Beta</Signature><Data>BASE64ENCODEDDATAGOESHERE</Data><MIB><Size>548</Size></MIB></Firmware><Firmware><Description>Firmware
Ver
1.3.1352</Description><ID>1000</ID><Size>42121</Size><Signature>ver.1.3.1352</Signature><Data>BASE64ENCODEDDATAGOESHERE</Data><MIB><Size>643</Size></MIB></Firmware></Packages></VersionMap>";
// DESERIALIZE HERE (Host::Utils::Xml::Deserialize is my serialization /
deserialization wrapper - I think this works correctly)
MVersionMap* VersionMap =
dynamic_cast<MVersionMap*>(Host::Utils::Xml::Deser ialize(xmlstr,
__typeof(MVersionMap)));
//

public __gc class MMib
{
public:
MMib()

{}
[XmlElement(DataType="unsignedInt", ElementName=S"Size", Namespace=S"",

UInt32 m_Size;
};

Thanks for the Help!
