Can't you use String.ToCharArray() ?

well, vb doesn't use the String.Split, it has it own which you can call from
the language of your choice.

c#

string[] r =
Microsoft.VisualBasic.String.Split("string1**string2**string3","**");

But the origional poster says "it treats the entire string as a separator".
Split a string using "as" as seperator will certainly not behave the same as
using 'a' and 's'...

uh?
what about (in 2.0 doc, I am not sure about 1.x)
public string[] Split(
string[] separator,
StringSplitOptions options
);

That is good to know. However, I think that requires loading that whole vb
dll and any supportive dlls. That is probabably is a pretty big cost for
one split function. Don't know the mem or perf cost as have not looked into
it, but something to think about. Naturally, the same can be done pretty
easy with a static regex method put in your utils library.

Time for you to learn c#

Indeed this overload is new in 2.0... the 1.x Framework only has
splitting on characters, not strings.
