重载采用具有不同类型的通用列表作为参数的方法 [英] Overloading a method that takes a generic list with different types as a parameter

问题描述

如何重载采用具有不同类型的泛型列表作为参数的方法?

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

例如:

我有两种类似的方法:

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

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

有没有办法将这两种方法结合在一起?

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

推荐答案

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.
