当然可以...使用泛型！

Sure can... using generics!

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

}

这假设您的分配"，"PAllocation"和"NPAllocation"都共享一些称为"BasePAllocationClass"的基类.否则，您可以删除"where"约束，并自行检查类型.

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.
