Question

How can I overload a method that takes a Generic List with different types as a parameter?

For example:

I have a two methods like so:

private static List<allocations> GetAllocationList(List<PAllocation> allocations)
{
    ...
}

private static List<allocations> GetAllocationList(List<NPAllocation> allocations)
{
    ...
}

Is there a way I can combine these 2 methods into one?

Answer 1

Sure can… using generics!

private static List<allocations> GetAllocationList<T>(List<T> allocations) 
   where T : BasePAllocationClass
{

}

This assumes that your “allocations”, “PAllocation” and “NPAllocation” all share some base class called “BasePAllocationClass”. Otherwise you can remove the “where” constraint and do the type checking yourself.
