How to remove an element from an array WITHOUT removing duplicates. in C#

Question

I needed to remove the first element from an array in my program. Here is the code:

input = input.Except(new string[] {input[0]}).ToArray();

This returns the difference between the original array and an array with the to be removed element. However, it also removes duplicates (I think).

When I input

average 10 20 10 30

it returns

10 20 30

Job done, but I don't want it to remove duplicates. How do I get it to stop removing duplicates?

I do realize that this question is a simalar question. Oops! — Bald Bantha

Instead of using LINQ Except, you could use Skip instead:

Bypasses a specified number of elements in a sequence and then returns the remaining elements.

input = input.Skip(1).ToArray();

Assuming the input variable has the type of List, you should be able to use:

input.Remove(input[0])

Remove will remove the first matching element it finds in the list.
