How would I do this?

我该怎么做？

    protected void SendMail()
    {
        var fromAddress = "[email protected]";
        var toAddress = "[email protected]";
        const string fromPassword = "mypassword";

        string subject = "New Email from Website";
        string body = "From: " + name.Text + "\n";
        body += "Email: " + email.Text + "\n";
        body += "Message: \n" + message.Text + "\n";

        var smtp = new System.Net.Mail.SmtpClient();
        {
            smtp.Host = "smtp.gmail.com";
            smtp.Port = 587;
            smtp.EnableSsl = true;
            smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
            smtp.Timeout = 20000;
        }
        // Passing values to smtp object
        smtp.Send(fromAddress, toAddress, subject, body);
    }

Set isBodyHtml to true, the following code describes it, To send a bold text you can use "<b> My bold text </b>". To send an italicized text you can use "<i> Italic text </i>". To send an underlined text you can use "<u> underlined text </u>".

将 isBodyHtml 设置为 true，下面的代码对其进行了描述，要发送粗体文本可以使用“ <b> My bold text </b>”。要发送斜体文本，您可以使用“ <i> Italic text </i>”。要发送带下划线的文本，您可以使用“ <u> underlined text </u>”。

You can copy and use the following method. By using this method, it will be very easy to send emails.

您可以复制并使用以下方法。通过使用这种方法，发送电子邮件将非常容易。

public static bool SendEmail(string To, string ToName, string From, string FromName, string Subject, string Body, bool IsBodyHTML)
{
    try
    {
        MailAddress FromAddr = new MailAddress(From, FromName, System.Text.Encoding.UTF8);
        MailAddress ToAddr = new MailAddress(To, ToName, System.Text.Encoding.UTF8);
        var smtp = new SmtpClient
        {
            Host = "smtp.gmail.com",
            Port = 25,
            EnableSsl = true,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = false,
            Credentials = new System.Net.NetworkCredential("your email address", "your password")
        };

        using (MailMessage message = new MailMessage(FromAddr, ToAddr)
        {
            Subject = Subject,
            Body = Body,
            IsBodyHtml = IsBodyHTML,
            BodyEncoding = System.Text.Encoding.UTF8,

        })
        {
            smtp.Send(message);
        }
        return true;
    }
    catch
    {
        return false;
    }
}

When you call this method call it like this

当你调用这个方法时，像这样调用它

 SendEmail("Here address to" , "Here to name" , "Here from", "here from name", "here subject" , here Body, " Here whether HTML or Plain" )

You need only few minor changes.

您只需要进行一些细微的更改。

1. say IsBodyHtmlis true
2. replace all \nwith <br/>

1. 说IsBodyHtml是true
2. 全部替换\n为<br/>

and here's the final the code

这是最后的代码

protected void SendMail()
{
    var fromAddress = "[email protected]";
    var toAddress = "[email protected]";
    const string fromPassword = "mypassword";

    string subject = "New Email from Website";
    string body = "From: " + name.Text + "<br/>";
    body += "Email: " + email.Text + "<br/>";
    body += "Message: <br/>" + message.Text + "<br/>";

    var smtp = new System.Net.Mail.SmtpClient();
    {
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;
        smtp.EnableSsl = true;
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
        smtp.Timeout = 20000;
    }
    // Passing values to smtp object
    smtp.Send(fromAddress, toAddress, subject, body,IsBodyHtml:true);
}

Hope that helps.
