Activator.Creat eInstance or InvokeMember? Code is not getting me where I want to go.

[hazz]

this is a repost with a hopefully more clearly stated scenario and more
concise questions at the end.
given the following two classes, my intent is to use pass a token into the
instantiated class DBPassword and return a string;
*************** *************** ********
public class DBPassword
{
public DBPassword()
{
//Empty constructor
}
public string GetPassword(Tok en token)
{
string sPassword = "Howdy Doody";
return sPassword;
}
}
*************** ***what I will pass into DB.GetPassword. GetPassword above
*************** *****
public class Token
{
protected string m_strPWD;
public Token()
{
}
public string Password
{
get
{
return m_strPWD;
}

set
{
m_strPWD=value;
}
}

*************** *************** ********

Token tkn = new Token();

tkn.Password = "password";

object[] args = {tkn}; //This is my intention, how do I do this?

Assembly assmbly = Assembly.LoadFr om("O:\\DBPassw ord\\DBPassword .dll");

Type[] types = assmbly.GetType s();
foreach (Type t in types)
{
mi = t.GetMethod("Ge tPassword");
if (mi != null)
{
DBPassword ppdr =
(DBPassword)Act ivator.CreateIn stance(t,Bindin gFlags.Public |
BindingFlags.In vokeMethod | BindingFlags.Cr eateInstance, null, args, null);
*************** *************** ********

When I run the above, "Constructo r on type DBPasswordProvi der.DBPassword not
found." } System.Exceptio n is thrown.

Why would this exception be thrown? There is a constructor for public
DBPassword.

Should I use Activator.Creat eInstance or InvokeMember?

How do I pass in the token as an arg if I do use CreateInstance?

Which of the 9 overloaded versions of Activator.Creat eInstance would I
choose for this?

Thank you very much,

p.s. I cross-posted with the remoting newsgroup as I wasn't sure which was
the best newsgroup for this question.
