Cloning elements in an array is not something that can be done in a universal way. Do you want deep cloning or a simple copy of all members?

Let's go for the "best effort" approach: cloning objects using the ICloneable interface or binary serialization:

public static class ArrayExtensions
{
  public static T[] SubArray(this T[] array, int index, int length)
  {
    T[] result = new T[length];

    for (int i=index;i

This is not a perfect solution, because there simply is none that will work for any type of object.
