Using InvokeMember to invoke a method

[Guest]

I'm having a problem with late binding. I'm able to create an instance of a class dynamically at runtime and set a property, as in the following

EventCollectionFilterType.InvokeMember("EventGUID", BindingFlags.SetProperty, null, oEventCollectionFilter, paramEventGUIDObject)

However, invoking a method using the following doesn't work, with a runtime error being generated, compaining that it cannot find the method

oEvent = EventCollectionType.InvokeMember("Item", BindingFlags.Public | BindingFlags.InvokeMethod, null, oEventCollection, paramItemObject)

I've checked the method, and it has a public modifier, as expected, and is visible when explicitly creating an object of that type in the usual way. What am I doing wrong?

Item looks rather as a property (or even as an indexer in C#) than as a
method. If this is the case, try invoking "get_Item" or "set_Item" methods.
You can also examine the assembly containing the EventCollectionFilter class
with the ILDASM tool to find out the exact name of the method.
