how to check aan UI panel is LastSibling or not?

Hi, I’m trying to check a panel is LastSibling or not. How can I do that with C#?
Please help.
Thanks in advanced.

Here’s a C# extension method that checks if a transform is the last sibling or not:

public static bool IsLastSibling(this Transform t)
{
	if(t != null && t.parent != null)
	{
		return t.GetSiblingIndex() == (t.parent.childCount - 1);
	}
	return true;
}
