[Juan]

Hi, I´m using System.Text.RegularExpressions, I want to find any acurrence
of the char & or % or |

Ehat is the correct sintax for the Match method? This is what I´m usinf but
is not working:
Match myMatch = Regex.Match(myString,"^[&|%]*$");

Thanks,

Juan.

static void Main(string[] args)

{

string myString = "1&2|3%4&5|6%";

Match m = Regex.Match(myString,@"[&\|%]");

int matchCount = 0;

The ^ and $ mean that the match should be the entire string (instead of
a substring).
The [..]* means that you will match zero or more occurrences of
the specified characters.
The [&|%] means that you will match "&", "|" and "%".

So: you will match only a string consisting entirely of &,| and/or %
characters (or an empty string).

To find any occurrence of one of those three characters, use
"[&|%]" as the RE.
