.Net Split with split characters retained

Question

Possible Duplicate:
C# split string but keep split chars / separators

Is there a simple way to do a .Net string split() function that will leave the original split characters in the results?

Such that:

"some text {that|or} another".Split('{','|','}');

would result in an array with:

[0] = "some text "
[1] = "{"
[2] = "that"
[3] = "|"
...

Preferably without a regex.

check out this post

the first answer with a RegEx solution, the second for a non-regex solution...

In Concept...

string source = "123xx456yy789";
foreach (string delimiter in delimiters)
    source = source.Replace(delimiter, ";" + delimiter + ";");
string[] parts = source.Split(';');

I got downvoted for this very answer. you a lucky guy! – D3vtr0n Nov 14 '12 at 22:53
@Devtron: Link only answers are discouraged, even if they link to stackoverflow. This one goes on to provide an example as well. (Just guessing by the way) – Guvante Nov 14 '12 at 22:54
@Guvante mine had a better example, further down in the answer list :) – D3vtr0n Nov 14 '12 at 22:55
@Devtron but much more complicated.... – adam Nov 14 '12 at 22:56
but this does not work for ";" characters. it may not be very complicated, but it has an obvious bug. – D3vtr0n Nov 14 '12 at 22:57
just "in concept". you could replace ';' with '^' depending on what data you allow your string – adam Nov 14 '12 at 22:58
accepts all input? make it something crazy big like '!@#%#$@#$#@' lol, that will never get hit by accident. – adam Nov 14 '12 at 22:59
hey, now youre talking! btw, I upvoted this, even though I got hated on. – D3vtr0n Nov 14 '12 at 23:49

you can probably roll your own using String.IndexOf Method (String, Int32) to find all of your initial separator characters, and merge those in with the results of String.Split
