Question How to make a single function to manipulate multiple types of list?

Hello! I have multiple lists of different types, but I need to do the same thing to them. But I don't know how/if there is a way to make a single function work with different types of lists.

Basically, I want to "sort" the lists in a random fashion. So I have code that randomizes the list. It works, but I was hoping to simplify and minimize my script by making a single function handle all of the lists instead of reusing the same code for each list. However, when I try to create the function, it won't let me use the same function for the different types of lists.

So how could I write a function to accept all of these different types?

Code (CSharp):

1. List<A> listA
2. List<B> listB
3. List<C> listC
4.  
5. void DoSomething ()
6. {
7.      RandomizeList(listA);
8.      RandomizeList(listB);
9.      RandomizeList(listC);
10. }
11.  
12. void RandomizeList (List<?> list)
13. {
14.      // Randomize order of list contents
15. }

Is there a way to do that? Thank you!

 

You can just make the method generic, most likely.

Like so:

Code (CSharp):

1. private void RandomiseList<T>(List<T> collection)
2. {
3. }

 

Thank you so much! Exactly what I needed! :-D
