Passing a List of Types to a Function

Question

C++ / C#

I have a function public void f(Type[] types)which, let's say, accepts types.
I need to register these types. To me it would look like this:

foreach(var type in types)
{
     Engine.RegisterType<type>();
}

Those. it is necessary to transfer each of the types to the template, but accordingly it is impossible, therefore I ask the question here: how to transfer a list of types to the function for their subsequent use in the template method?
The method is necessarily template (from third-party libraries). It is unlikely to be
used , since only 1 type is passed here, calling the function multiple times is also not an option.public void f<T>()

Answer 1

To be honest, it's not very clear why you don't have information about the types that you need to register... and what's wrong with the f option? provide more complete information - there may be a better solution. however, here is the code that solves this problem:

var mi = Engine.GetType().GetMethod("RegisterType"); // хотя, этот тип уж точно известен), лучше typeof
foreach (var type in types)
    mi.MakeGenericMethod(new[] { type }).Invoke(null, null);

Answer 2

No way. The template engine needs to get the concrete type at compile time. In this situation, the concrete type is only known at run time.
