Generic Extension Methods C#

Question

I'm creating a few extension methods that i want to use on different collections mostly those that implement IList and array collections [] whenever im creating an extension method i need to create 2 instead of just 1 so that it can work for both

    public static IList<T> Shuffle<T>(this IList<T> inputCollection)
    {

    }

    public static T[] Shuffle<T>(this T[] inputCollection)
    {

    }

Most of my methods require work with the indexes so i cant use IEnumerable is there some other way that i can write just 1 extension method and use it for both of the desired collections ? Also sometimes i use the string which is one more method.

Answer 1

You can try

public static IEnumerable<T> Shuffle<T>(this IEnumerable<T> value)

signature; and use it

IList<T> list = Shuffle(myList).ToList();
T[] array = Shuffle(myArray).ToArray();

or even

IList<T> list = myList.Shuffle().ToList();
T[] array = myArray.Shuffle().ToArray();

Answer 2

我建议使用此扩展方法，因为所有List对象都是从IEnumerable继承的。

public static IEnumerable<T> MethodName<T>(this IEnumerable<T> value)
