Hey All,
I have a textbox.
In that some entries are made like
textbox.text = Tendulkar,Sachin(srt);Dhoni,MS(msd);Sehwag,Virender(viru);D'Souza,Tim(tdsc)

I want an array of string which will have values like (srt,msd,viru,tdsc).
I guess we will first have to go around splitting by (';') and get a result array set of this.
and then split with ('(') and (')').
A for loop inside another is what i guess.

How can i get this??
Appreciate if u cud help me out.

Thanks
Akshay

You described what you have to do. Just do it....(N.B it is not a "for" inside a "for", like you described it: First you separate by ";" and afterwards you analyze the separated strings for "(...)").

But try to also to think forward. E.g. What should happen if somebody enters "Tendulkar(xyz),Sachin(srt);Dhoni,MS(msd);Sehwag,Virender(viru);D'Souza,Tim(tdsc)"

...first have a look to OriginalGriff's answer ;)

Easier way is to use a Regex:

C#

string s = "Tendulkar,Sachin(srt);Dhoni,MS(msd);Sehwag,Virender(viru);D'Souza,Tim(tdsc)";
Regex reg = new Regex(@"(?<=\().+?(?=\))");
MatchCollection matches = reg.Matches(s);
List<string> separated = new List<string>();
foreach (Match m in matches)
    {
    separated.Add(m.Value);
    }

There are whole books on Regular expressions!
This one is good:
http://www.amazon.co.uk/Regular-Expressions-Cookbook-ebook/dp/B008Y4OP1O/ref=sr_1_2?ie=UTF8&qid=1382275394&sr=8-2&keywords=regular+expressions
As is this:
http://www.amazon.co.uk/Mastering-Regular-Expressions-ebook/dp/B007I8S1X0/ref=sr_1_6?ie=UTF8&qid=1382275394&sr=8-6&keywords=regular+expressions
But look at Google and you'll find loads of basic tutorials which will explain them better than I can in a small textbox...
This is worth downloading as well:
http://www.ultrapico.com/Expresso.htm
Expresso - it's free, and it examines and generates Regular expressions.
