hello sir,

please help me out for a asp.net(c#) problem.
actually i want to make an online test series.
for that i want to paste each question with options into cute editor.
each question has 4 options(named: a. , b. , c. , d. ).
like this:
Question:
 f is defined on [-1, 1] by 

a.        f is continuous if and only if a > 0

b.       f¢ (0) exists if and only if a > 1

c.        f¢ is bounded if and only if a ³ 1 + c

d.       none of these

a. , b. , c. ,d. are the options

i want to split these above question as:

 f is defined on [-1, 1] by 
f is continuous if and only if a > 0
f¢(0) exists if and only if a > 1
f¢ is bounded if and only if a ³ 1 + c
none of these

i think  you clearly understand my problem.
please help me out.

my code is:

using System.Text.RegularExpressions;

string[] abc = Regex.Split(finalString, "( a. | b. |c. |d. )");

foreach (string match in abc)
{

string FinalSplitString= match;

}
where final string is the string which i mention above.

please help me.
