C#. Delete a known element from an array.

BrokenArrows

I have the need to delete an element from an array. The element will always be the last in the array.

I could just create a new array and move only the elements i want into it or is there an easier way?

Set the element to null, let the garbage collector do it's thing. But that would not resize the array.

If you want to do that, use a different data structure, like, say, List<T> and the RemoveAt function.

In fact, take a look at all the generic collection classes here. You should know them very well. Arrays are great and all, but they're limited.

Data structures and string manipulation. The two things I look at first when learning a new language / framework.

The List is alot more flexible.

List is definitely the way to go. Use .ToList<>() to convert your array and then you can remove the element using RemoveAt().

I guess Arrays are more lightweight, but OP probably not worrying about that.
