c# - Exception occuring while extracting the value of the node in xdocument -

-

i have xml : 

<runresult>   <previewrecords></previewrecords>   <recordsprocessed>100</recordsprocessed>   <logerror>false</logerror> </runresult>

i using following command fetch value of node recordsprocessed , 

int nofrecords = 0; nofrecords = convert.toint32(xdrunresultdoc.root.element("runresult").element("recordsprocessed").value;

but @ line throwing exception " object reference not set instance of object".

please suggest going wrong.

xdrunresultdoc.root points <runrdesult> element, don't have call element("runresult") again.

and suggest using (int) casting on xelement instead of convert.toint32: xelement explicit conversion (xelement int32)

int nofrecords = (int)xdrunresultdoc.root.element("recordsprocessed");
