Function to test whether 2 array of objects are equal or not.

public static bool AreEqual(object[] o1, object[] o2)

{

if (o1 == null && o2 == null)

{

return true;

}

if (o1 == null || o2 == null)

{

return false;

}

if (o1.Length == o2.Length)

{

int i;

bool eq = true;

for (i = 0; i

{

if (AreNotEqual(o1[i], o2[i]))
