Hi all,

I got a great answer the question below using the regex method instead.
string input = "MKWVTFISLLLLFSSAYSRGVFRRDTHKSEIAHRFKDLGEEHFKGLVLIAFSQYLQVK"

Another question:
What if I wanted to skip splitting at a delimiter say every 3rd instead of every time it reaches the delimiter?

so say
"one miss" would read
MKMVTFISLLLLFSSAYSR
GVFR
R
DTHKSEIAHR etc

How would I use the split string method using multiple delimeters but keep the delimeters?

Ex:

string input = "MKWVTFISLLLLFSSAYSRGVFRRDTHKSEIAHRFKDLGEEHFKGLVLIAFSQYLQVK";
string[] words = newString.Split('R','K');
for (int i = 0; i <; words.Length - 1; i++)
{
    sw.WriteLine(words[i]);
    char[] sumLine = words[i].ToCharArray();

}

I want it to read
MK
WVTFISLLLLFSSAYSR
GVFR
R
DTHK
SEIAHR etc etc

basically split the string on K or R but keep the K or R when I writeline the sequence

Regex will probsbly come to your rescue- try string[] words = Regex.Split(input, @"([RK])").
I think I've got the Regex wrong - but I hope you get the drift.

Your best best is to use a Regex rather than Split: split does not keep the delimiter:

string input = "MKWVTFISLLLLFSSAYSRGVFRRDTHKSEIAHRFKDLGEEHFKGLVLIAFSQYLQVK";
Regex regex = new Regex("([^KR])*[KR]");
MatchCollection ms = regex.Matches(input);
foreach (Match m in ms)
   {
   Console.WriteLine(m.Value);
   }
