Question

I have a custom type, which is abstract.
and will have some class to extend the abstract class.

somewhere i need to deal with a list of object which are the children my custom abstract type.

i am wonder in C#, can i do somthing like this:

void Method(List<? is CustomType> objs)
{
}

thx

Answer 1

i think what you are looking for is a generic method. Those are definitely supported:

void Method<T>(List<T> objs) where T: CustomType
{
}
