子 XElement 的索引

Question

Given an XElement is there a way to find out that element's index within the parent container?

I know there must be but I just can't figure it out!

Thanks!

Answer 1

Try e.ElementsBeforeSelf().Count()

Answer 2

Try using .ToList().IndexOf() which returns the index of the object you pass in. Example:

var index = document.Elements().ToList().IndexOf(element);

Answer 3

In VB

Dim Index As String = i.ToString.IndexOf(i.ToString)
