是否可以使参数实现两个接口? [英] Is it possible to make a parameter implement two interfaces?

问题描述

是否可以定义一个函数来接收一个必须实现两个接口的参数?

Is it possible to define a function that takes in a parameter that must implement two interfaces?

(这两个接口是我脑中浮现的，不是我想用的)

(The two interfaces are ones I just remembered off the top of my head; not the ones I want to use)

private void DoSomthing(IComparable, ICollection input)
{

}

推荐答案

您可以:

1) 定义一个继承两个必需接口的接口:

1) Define an interface that inherits both required interfaces:

public interface ICombinedInterface : IComparable, ICollection {... }

private void DoSomething(ICombinedInterface input) {... }

2) 使用泛型:

private void DoSomething<T>(T input)
    where T : IComparable, ICollection
{...}
