Question

I got a string array and values are as follows

sNames[0] = "Root | [<root>] | [ID = 1]";
sNames[1] = "Planning | [Root] | [ID = 2]";

From this I would like to just extract ID value .. 1,2..

for now am do this as :

foreach (var s in sNames)
{
  int id = Convert.ToInt32(s.Split('|')[2].Split('=')[1].Substring(1,1));
  ...
}

Is there some other good way to do it ?

Thanks

You can use a regex to find the ID (the Match() part may not be 100% correct — exercise left to the reader).

var regex = new Regex(@"\[ID = (?<id>[0-9]+)\]");
var ids = sNames.Select(s => Convert.ToInt32(regex.Match(s).Groups["id"].Value));
