EmailValidator Class

The EmailValidator class is a simple email validator that uses regular expressions to validate the correctness and syntactical accuracy of an email address.

Regular Expression Pattern

The EmailValidator class uses the following regular expression pattern for email validation:

private static readonly string EmailPattern = @"^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$";

Methods

IsValidEmail

public static bool IsValidEmail(string email)

The IsValidEmail method validates whether the given email address is valid according to the specified regular expression pattern.

Parameters

• email (string): The email address to validate.

Returns

• true if the email address is valid.
• false if the email address is not valid.

Remarks

• The email address must not be null, empty, or contain only whitespace characters.
• The method uses the regular expression pattern EmailPattern to validate the email address.
• The pattern allows email addresses with alphanumeric characters, dots, underscores, percent signs, plus signs, and hyphens in the local part.
• The domain part is allowed to contain alphanumeric characters, dots, and hyphens, with at least two letters at the end.

Example

using XValid;

string email = "user@example.com";
bool isValid = EmailValidator.IsValidEmail(email);

if (isValid)
{
    Console.WriteLine("Valid email address!");
}
else
{
    Console.WriteLine("Invalid email address!");
}

That's it! You can use the EmailValidator class in your C# code to validate email addresses based on the defined regular expression pattern.
