Convert a BindingList<T> to an array of T

Question

What's the easiest way to convert a BindingList<T> to a T[] ?

EDIT: I'm on 3.0 for this project, so no LINQ.

Answer 1

Well, if you have LINQ (C# 3.0 + either .NET 3.5 or LINQBridge) you can use .ToArray() - otherwise, just create an array and copy the data.

T[] arr = new T[list.Count];
list.CopyTo(arr, 0);

Answer 2

In .Net 2 you have to use .CopyTo() method on your BindingList<T>

Answer 3

I've changed this post since I noticed you tagged this with .net2.0. You could use a List since it has an ToArray() method.

public T[] ToArray<T>(BindingList<T> bindingList) {
    if (bindingList == null)
        return new T[0];

    var list = new List<T>(bindingList);
    return list.ToArray();
}

Note: This is indeed a less performant solution than the CopyTo solution that other members have shown. Use their solution instead, this one creates two arrays, the result and one internal to the List instance.
