[Mono-list] XPathNavigator.Evaluate casting

[Kris Luyten]

Hi,

I have a small question concerning the XPathNavigator.
The msdn documentation shows the Evaluate method can be casted,
so I used (m_vocabulary is an XPathNavigator):

XPathExpression xpCountExpr =
m_vocabulary.Compile("count(//d-class[@id='label']/d-property[@id='constructor']/d-param)");
int nrp = (int)m_vocabulary.Evaluate(xpCountExpr);

But that did not work: I got a castexception in the line following on
the "int npr" assignment. (Other similar pieces of code had the same
effect).
So now I changed the code into:
int nrp = Int32.Parse(m_vocabulary.Evaluate(xpCountExpr).ToString());
and this works correctly.

Is this because of my misunderstanding of the documentation or due to a
bug or unfinished code in mono?

Regards,
Kris
