Exception parsing querystring

[duncan.welch]

Hi,

I've got a website that uses links for page positioning which works
great about 99% of the time. For some reason, 1% of the time I'll get
an error when parsing the querystring, as it's reading the anchor name
as part of the number.

e.g.
http://www.fluidstyle.co.uk/venuedetails.aspx?venueID=1964#review

occasionally gives an error on the line:

int venueID = Convert.ToInt32(Request.QueryString["venueID"]);

Has anyone come across this before, and if so how did they manage to
solve it?

Thanks in advance,

Duncan

Your "?venueID=" may contain strings symbols thus during converting got
excetion.
Try to use either Int32.TryParse or use regext before type casting to be
sure that you venueID contains number symbols.

Thanks for the feedback; the venue ID definately is numeric, as I'm
logging the errors. I can even cut and paste the querystring from the
error message in, and it *normally* works.

It just seems to be reading the # as part of the querystring.

Any other ideas?

Hi Michael,

The # should terminate the querystring, and be read by the browser as a
position on the page to jump do, defined with an anchor (e.g. <a
name="reviews"></a>).

What appears to be happening occasionally is .NET is reading the
#review as part of the venueID=1964 Querystring key/pair, and throwing
a number format exception.

I'm completely at a loss to why this is happening, and I'm really
surprised other people haven't come across this!

Michael,

Here's a URL that has previously broken it. Please note the caveat -
it works 99 out of 100 times!

http://www.fluidstyle.co.uk/venuedetails.aspx?venueID=1964#review
