Hi,
I have a runtime generated class (a WCF proxy) that extends a generic type.
The generated code is:

[DebuggerStepThrough, GeneratedCode("System.ServiceModel", "3.0.0.0")]
public class _MyTypeClient : ClientBase<_MyType>, _MyType
{
.....
}
Now I would like to call some methods from an instance of this class.
The problem is that _MyType is also generated code, so I can't cast to the
correct type:
((ClientBase<_MyType>)myInstance).ClientCredential s.UserName.UserName =
"jimmy";

How can I achieve this?

Hallo Carlo!

Why not just:
myInstance.ClientCreditials.UserName.UserName = "jimmy";
?

Hi Günter,
the proxy type is dinamically created, so the variable is of type object.
To access the method on it I have to cast it to the appropriate type.

(_MyTypeClient)myInstance.ClientCredentials... is not possible?


If no: When static typing is not possible, you need to get the System.Type
Objects. Without them it is not possible.

e.g.
Type tClientBase = typeof(ClientBase<>);
Type tType = Type.GetType("Namespace._MyType, Assembly", true);
Type tMyClient = tClientBase.MakeGenericType(tType);

// now you can reflect on tMyClient to invoke Methods late-bound (e.g.
GetProperty on "ClientCredentials").

When you have an underlying and non-generic interface you can use this for
early-bound access.

BTW: Maybe there is a WCF specific solution for you problem.

Thanks for G?ter's informative input.

Hi Carlo,

Do you mean the "_MyType" type is dynamically compiled and
generated(through .NET compiler api)? If so, I'm afraid you can not
statically use type name in your application code, but have to use
Type.GetType to get the type instance of that dynamic generated
type(through full typename).

G?ter has posted some code snippt on this, after you get the type object of
your dynamic generated proxy/interface, you can use standard reflection API
to invoke method/property against the actual proxy instance.

I think this is a typical dynamic code generation and late-binding case and
WCF hasn't particular solution for it except using reflection.

Hi Steve,
I want to use windows authentication, I'm having trouble also with the
'normal' generated proxy.
When I solved those problem I will try Gunter and yours suggestions.
Thanks.
