Testing Regex for Alphanumeric Value validation

[Abhijeet Khopade]

Hi,

I am using regex validator in our code. This validator is working for some of the Regular Expressions like validating CC and Bank Account number. But method is not working to Validate Alphanumeric values like (D23145890 or XJ13256141).

My code is as below -

foreach (var regex in m_aRegexes)
{
Regex oRegex = (Regex) regex;

mc = oRegex.Matches(m_sTxt);

if(mc.Count > 0)

Return True;

Else

Return false;

}


Working Regex -

1) (^[a-z0-9][-a-z0-9._]+@([-a-z0-9]+\.)+[a-z]{2,5}$)

2) (\d{3}-\d{3}-\d{4}|^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$)


Non Working Regex -

1) (^(?!^0+$)[a-zA-Z0-9]{3,20}$)

2) (^E\d{6}?$)


Can somebody please help me here?
