如何让一个方法接受两种类型的数据作为参数? [英] How to let a method accept two types of data as argument?

问题描述

我有一个方法，接受一个Hashtable(是的，我知道，它已经过时了..)作为参数:

I have a method, accepting a Hashtable (yes I know, it's outdated..) as argument:

public static LuaTable HashtableToLuatable(Hashtable t, int depth = 1)

这正常工作.

现在，我也想接受ArrayList作为第一个参数，因此您可以让't'同时具有Hashtable和ArrayList的值.目前，我已经两次复制粘贴了该方法，如下所示:

Now I'd like to accept an ArrayList as first parameter as well, so you can let 't' have the value of both a Hashtable and an ArrayList. Currently I have copy-pasted the method two times, like this:

public static LuaTable ArraylistToLuatable(ArrayList t, int depth = 1)

其余的完全一样.

我认为有办法将其合并.

I think there's a way to merge this.

推荐答案

两个类都实现了ICollection接口，因此，如果您的通用代码"将与ICollection接口的定义冲突，则可以将其用作参数类型.

Both classes implement the ICollection interface, so if your 'common code' will work against the definition of the ICollection interface, you could use that for your parameter type.
