Okay, this isn't a big deal but I ran into a situation where it was convenient to be able to create a class without knowing it's type until runtime. All the classes in this namespace derive from a base class so certain functionality it guaranteed in each one. This is how we did it:
tType = Type.GetType("XmlRouter." + sCurrentNodeName);
if( tType != null ) {
object o = Activator.CreateInstance(tType); }
// the function we want to use has XML parameters
XmlNode[] args =
new XmlNode[2]; args[0] = oXmlHeaderNode;
args[1] = oNode;
// invoke method
object
oOut = tType.InvokeMember("ProcessRequest", BindingFlags.Default | BindingFlags.InvokeMethod, null, o, args);
