Email validator

[amorphis88]

I need an email validator in C#... i never written a letter C#...

i found this:

public static bool isEmail(string inputEmail)
{
   inputEmail  = NulltoString(inputEmail);
   string strRegex = @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" +
         @"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" + 
         @".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$";
   Regex re = new Regex(strRegex);
   if (re.IsMatch(inputEmail))
    return (true);
   else
    return (false);
}

but do i need to import Regex or something?

thanks!

thanks, it works now..

but the rest of my project is in vb.net

how can i use my class EmailValidator.cs in my form1.vb?
the function is a boolean isEmail (see above)

If you just have this one, suggest you translate it to VB!
e.g. the line
Regex re = new Regex(strRegex);
would translate to
Dim re As New Regex(strRegex)
etc.

it's a task for school.. it HAS to be C#
looking already for days

a suggestion that i found is create another project only in C#and import the .dll file in my vb.net project..

other possibilities?

Under .NET you can as easily import a dll written in VB in C# as you can do the opposite, so go ahead if it HAS to be C#. I believe that is part of this learning exercise.

yes, probably it is, but it's hard without no explanation

If you are using Visual Studio(I don't know that) then this might help:

thanks for the help i found the solution:

create csharp project
make class with above a namespace ...
build it
in vb.net project add the reference
then import namespace ...
and ready to go!
