Accessing binary data from registry key

[Sharon McCarty]

Hi Everyone,

I have a managed C++ web service and I'm trying to access the registry
key that contains a binary data.

Can someone tell me how to convert object __gc* to byte[]?

I've got some code:

-----------------------------------------------------------------------
RegistryKey *pIdentityKey;
RegistryKey *pRootKey;

pRootKey = Registry::LocalMachine->OpenSubKey("SOFTWARE",false);

pIdentityKey = pRootKey->OpenSubKey("Proj\\identity\\ASPNET_SETREG");

byte userNameBytes[255];
userNameBytes = (byte[]) pIdentityKey->GetValue("userName");
-----------------------------------------------------------------------
the compiler complains on the last line that:

c:\Documents and Settings\sharon\My Documents\Visual Studio
Projects\TestManagedC++WS\TestManagedC++WSClass.cp p(32): error C2440:
'type cast' : cannot convert from 'System::Object __gc *' to 'byte []'
Can someone tell me how I can get the registry key in byte[] format?

Thank you!

Sharon
