I am trying to dynamically load my authentication server type based on a setting. I am hung up on how to cast to a type when I don't know the type.

   Type t = Type.GetType(WebConfigurationManager.AppSettings.Get("AuthenticationSvcImpl"));
    IAuthenticationService authCli = Activator.CreateInstance(t);
    return authCli.AuthenticateUser(login);

I know there is Convert.ChangeType(), but that just converts to an object...

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

Hi, I'm using a class which applies a visual reflection-effect to defined movieclips. I use a reflection-class from here: link to source.

System.Reflection - Global methods aren't available for reflection

I have an issue with a semantic gap between the CLR and System.Reflection. System.Reflection does not (AFAIK) support reflecting on global methods in an assembly. At the assembly level, I must start with the root types. My compiler can produce assemblies with global methods, and my standard bootstrap… >>> More
