regex that matches a string containing 6 alpha, 2 alphanumeric and 3 OPTIONAL alphanumeric

Reply Quote

I need a regex that matches a string containing 6 alpha, 2 alphanumeric and 3 OPTIONAL alphanumeric, upper and lower case. I need this for validating strings in ASP.net 2.

Eg:.

abcdefab345
abcdef22
abcdef5e
abcdef3ee5e
abcdef55asd
abcdefr5

and should not match

abcs
abcd34d3
abcdef23f
abcdefd
abcdef
