C# Array initialization - with non-default value

Question

What is the slickest way to initialize an array of dynamic size in C# that you know of?

This is the best I could come up with

private bool[] GetPageN

Many times you'd want to initialize different cells with different values:

public static void Init(this T[] arr, Func factory)
{
    for (int i = 0; i < arr.Length; i++)
    {
        arr[i] = factory(i);
    }
}

Or in the factory flavor:

public static T[] GenerateInitializedArray(int size, Func factory)
{
    var arr = new T[size];
    for (int i = 0; i < arr.Length; i++)
    {
        arr[i] = factory(i);
    }
    return arr;
}
