In this article I will explain how to validate email address with an example. Here I am using regular expression to validate the email address. You need to import System.Text.RegularExpressions for reference.
static void Main(string[] args)
{
try
{
string emailId = "dummygmail.com";
if (!string.IsNullOrEmpty(emailId))
{
string emailRegex = @"^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$";
Regex re = new Regex(emailRegex);
if (!re.IsMatch(emailId))
{
Console.WriteLine("Please Enter Correct EmailAddress.");
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadLine();
}
