How to Make CC Field Optional Using ASP.NET

When working with ASP.NET, there may be situations where you want to make the CC (Carbon Copy) field optional in a form. This can be achieved using the Postal library, which provides a convenient way to send emails in ASP.NET .

To begin, make sure you have the Postal library installed in your project. You can do this by the following package to your project:

Install-Package Postal

Once you have the Postal library installed, you can proceed with the CC field optional. Here's an example of how you can achieve this:

using Postal;

public  EmailModel : Email
{
    public string To { get; set; }
    public string Subject { get; set; }
    public string Body { get; set; }
    public string CC { get; set; }

    public EmailModel(string to, string subject, string body, string cc = null)
    {
        To = to;
        Subject = subject;
        Body = body;
        CC = cc;
    }
}

public class EmailService
{
    public void SendEmail(string to, string subject, string body, string cc = null)
    {
        var email = new EmailModel(to, subject, body, cc);
        email.Send();
    }
}

In the above example, we define an EmailModel class that inherits from the Email class provided by the Postal library. This allows us to easily send emails using the Postal library. The EmailModel class has for the recipient's email address (To), the email subject (Subject), the email body (Body), and the CC field (CC).

The constructor of the EmailModel class accepts the required parameters for sending an email, such as the recipient's email address, subject, and body. The CC field is optional and has a default value of null. This means that if no value is provided for the CC field, it will be omitted from the email.

The EmailService class provides a called SendEmail that takes the necessary parameters for sending an email. It creates an instance of the EmailModel class and the Send method to send the email.

Here's an example of how you can use the EmailService class to send an email with an optional CC field:

var emailService = new EmailService();
emailService.SendEmail("recipient@example.com", "Hello", "This is the email body", "cc@example.com");

In the above example, we create an instance of the EmailService class and call the SendEmail method with the required parameters for sending an email. We also provide a value for the optional CC field, which will be included in the email.

If you don't want to include a CC field in the email, you can simply omit the last parameter when the SendEmail method:

emailService.SendEmail("recipient@example.com", "Hello", "This is the email body");

In this case, the CC field will be omitted from the email, making it optional.

By following the above steps and using the Postal library, you can easily make the CC field optional when sending emails in your ASP.NET application.
