Send EMail through Gmail in C#

To send an email through Gmail in C#, you can use the SmtpClient class and the MailMessage class from the System.Net.Mail namespace. Here's an example:

using System.Net;
using System.Net.Mail;

public static void SendEmail(string to, string subject, string body, string from, string password)
{
    var smtpClient = new SmtpClient("smtp.gmail.com")
    {
        Port = 587,
        Credentials = new NetworkCredential(from, password),
        EnableSsl = true,
    };

    var mailMessage = new MailMessage(from, to, subject, body);

    smtpClient.Send(mailMessage);
}

In this example, the SendEmail method takes the email recipient (to), subject (subject), body (body), email sender (from), and password (password) as arguments. It creates a new SmtpClient instance for the Gmail SMTP server, sets the required credentials and SSL settings, and creates a new MailMessage instance with the email data. Finally, it sends the email using the SmtpClient object's Send method.

To send an email with an attachment through Gmail in C#, you can use the Attachment class and the MailMessage class from the System.Net.Mail namespace. Here's an example:

using System.IO;
using System.Net;
using System.Net.Mail;

public static void SendEmailWithAttachment(string to, string subject, string body, string from, string password, string attachmentPath)
{
    var smtpClient = new SmtpClient("smtp.gmail.com")
    {
        Port = 587,
        Credentials = new NetworkCredential(from, password),
        EnableSsl = true,
    };

    var mailMessage = new MailMessage(from, to, subject, body);

    var attachment = new Attachment(attachmentPath);

    mailMessage.Attachments.Add(attachment);

    smtpClient.Send(mailMessage);
}

In this example, the SendEmailWithAttachment method takes the same arguments as the SendEmail method, as well as an additional attachmentPath argument that specifies the path to the attachment file. It creates a new Attachment instance from the file path, adds the attachment to the MailMessage object's Attachments collection, and sends the email with the attachment using the SmtpClient object's Send method.

To send an email with an attachment from a MemoryStream through Gmail in C#, you can use a similar approach to the previous example, but instead of using a file path, you can use the MemoryStream object's ToArray method to get the byte array of the attachment data. Here's an example:

using System.IO;
using System.Net;
using System.Net.Mail;

public static void SendEmailWithMemoryStreamAttachment(string to, string subject, string body, string from, string password, MemoryStream attachmentStream, string attachmentFileName)
{
    var smtpClient = new SmtpClient("smtp.gmail.com")
    {
        Port = 587,
        Credentials = new NetworkCredential(from, password),
        EnableSsl = true,
    };

    var mailMessage = new MailMessage(from, to, subject, body);

    var attachmentData = attachmentStream.ToArray();

    var attachment = new Attachment(new MemoryStream(attachmentData), attachmentFileName);

    mailMessage.Attachments.Add(attachment);

    smtpClient.Send(mailMessage);
}

In this example, the SendEmailWithMemoryStreamAttachment method takes the same arguments as the previous example, as well as an additional attachmentStream argument that specifies the MemoryStream object containing the attachment data,
