[IronPython] SslStream exception

[Dino Viehland]

Assuming that you're defining ValidateServerCerificate as a member of a class you'll need to add a "self" parameter to it, eg:

class foo(object):
        def ValidateServerCertificate(self, sender, certificate, chain, sslPolicyErrors):
              return True

That will cause the expression "self.ValidateServerCertificate" to produce a bound method which contains the function + the reference to self and Python should be able to expose that method as a 4 parameter delegate which receives sender, certificate, chain, sslPolicyErrors.  Or you can just define VSC as a top-level function or a static method and not have it take self.

Thanxs a lot.

Now, I'm having another issue ... I want to bypass the Validation of
the server  certificate but looks like the callback funtion is not
working properly.
Is this the way to create the Sslstream:

sslStream = SslStream( client.GetStream(), False,
RemoteCertificateValidationCallback ( self.ValidateServerCertificate),
None)

------------------

def ValidateServerCertificate( sender, certificate, chain, sslPolicyErrors):

      return True


regards,

gara

To catch a .NET exception as a Python exception you need to catch the closest base exception which might be Exception or SystemError (if you let the exception go unhandled it's whatever gets reported there).  To catch the .NET exception you just need to grab it from the correct namespace, for example:
