Check if variable value is a valid email.

[Shapper]

Hello,

I have an aspx.vb code with a function.
In this function I need to check if a variable is a valid email address.

Something like: (e-mail address removed)

How can I do this?

Thanks,
Miguel

Hi Miguel:

You can use a RegEx Validation control. Here is a walkthorugh to get
started with:

Then when you're ready to write the regex, I highly suggest using
regexlib.com, plenty to choose from depending on how particular you want
to be:

Hello,

I know the ASP.NET build in validation control to place in HTML code.

What I need is to check if variable myEmail has a valid email address.
I need to do this in my vb.net code in my aspx.vb code file.

Can someone send me an example of how to create this?

Thanks,
Miguel

You can use the following syntax

If System.Text.RegularExpressions.Regex.IsMatch("youemail", "^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$") = True Then

if it is valid then it will return true
