c# - Using RegEx to Split the Url -

i want split url 2 part using regex. have saved xml response datatable , iterate through each row using foreach. when use datatable value regex 0 available. when use array index 1 give following exception.

system.indexoutofrangeexception: index outside bounds of array. 

the following gives , exception.

foreach (datarow row in ndt.rows) {     string imgurl =row["image1"].tostring();      string[] fimgurl = regex.split(imgurl, @"small/");     string  simgurl = fimgurl[1]; } 

the following it's working without issue.

foreach (datarow row in ndt.rows) {     //textbox1.text = row["imagepath"].tostring();     string imgurl ="http://www.hotelbeds.com/giata/small/12/124356/124356a_hb_w_001.jpg";     string[] fimgurl = regex.split(imgurl, @"small/");     string  simgurl = fimgurl[1]; } 

i have saved same url string in datatable. couldn't find what's wrong that. can please me on this?

some people, when confronted problem, think "i know, i'll use regular expressions." have 2 problems. --jamie zawinski

var uri = new uri("http://www.hotelbeds.com/giata/small/12/124356/124356a_hb_w_001.jpg");  var firstpart = uri.host + string.concat(uri.segments.take(3));   // returns: "www.hotelbeds.com/giata/small/"  var lastpart = string.concat(uri.segments.skip(3));   // returns: "12/124356/124356a_hb_w_001.jpg" 

if need http, can use uri.scheme. change 3 other number if want split in different place.

additionally can search uri.segments index of directory want if changes.
