I am trying to create a regex validation attribute in asp.net mvc to validate

  • 0

I am trying to create a regex validation attribute in asp.net mvc to validate that an entered email has the .edu TLD.

I have tried the following but the expression never validates to true…

[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+edu

and

\w.\w@{1,1}\w[.\w]?.edu

Can anyone provide some insight?

    This should work for you:

    ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.+-]+\.edu$
    

    Breakdown since you said you were weak at RegEx:

    ^ Beginning of string

    [a-zA-Z0-9._%+-]+ one or more letters, numbers, dots, underscores, percent-signs, plus-signs or dashes

    @ @

    [a-zA-Z0-9.+-]+ one or more letters, numbers, dots, plus-signs or dashes

    \.edu .edu

    $ End of string
