Hi Arjun,
You can throw in a string validation for email using regex!

you can use the pattern:

C#

string emailValidationPattern = "^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";

An other option is to use a trick to check it with creating a new MailAddress:

C#

public bool IsValid(string emailaddress)
{
    try
    {
        MailAddress m = new MailAddress(emailaddress);
        return true;
    }
    catch (FormatException)
    {
        return false;
    }
}

Cheers,
Edo

I think below is the line which is causing the error.

C#

MailAddress to = new MailAddress("strto");

You need to provide proper email Id, like the one you have provided in

C#

MailAddress from = new MailAddress("arjun.w@intellectbizware.com");
