Convert a BindingList<T> to an array of T

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.

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.

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);

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