List<T>
already has an Insert
method that accepts the index you wish to insert the object. In this case, it is 0. Do you really intend to reinvent that wheel?
If you did, you'd do it like this
public static class MyExtensions
{
public static void AddToFront<T>(this List<T> list, T item)
{
// omits validation, etc.
list.Insert(0, item);
}
}
// elsewhere
List<int> list = new List<int>();
list.Add(2);
list.AddToFront(1);
// list is now 1, 2
But again, you're not gaining anything you do not already have.
