Question

I’m trying to get the first image from this site but I keep getting an error and can’t quite figure out why..

Here’s the code:

string pictureurl = webdoc.DocumentNode.SelectSingleNode("//div[2]/table[1]/tr/td/a").Attributes["href"].Value;

and the error is Object reference not set to an instance of an object.

Can anyone please tell me why? if I remove the above line it works fine..

Answer 1

Your xpath is not correct to get a img

please use this way

string pictureurl = 
webdoc.DocumentNode
.SelectSingleNode("//div[2]/table[1]/tr/td/a/img")
.Attributes["src"].Value;
