Question How can I check validty of the email address in a login form?

[machel]

I've made a form that can check the existence of @ in the login form. How can I improve the checking of email address to make sure that @ cannot be the first or last character of the email address and there is exactly 1 @ in the email address?

Hi,

Have a look here:-

Hope that helps.

Hi,

I take it then that you have not used Regular Expressions before? If not have a look at these:-

Regex Class (System.Text.RegularExpressions)

Regex.IsMatch Method (String) (System.Text.RegularExpressions)

Then use the RegEx expression provided in my first post to help solve your problem.

Hope that helps.

Cheers,

Ian

You can use MailAddress class. It includes format validity checking.
