C#发送HTML和Text电子邮件 - 最优雅？

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

public class EmailSender
{
    public void SendEmail(string toEmail, string subject, string body, bool isHtml)
    {
        // 创建一个MailMessage对象
        MailMessage mailMessage = new MailMessage();
        mailMessage.From = new MailAddress("your_email@example.com");
        mailMessage.To.Add(toEmail);
        mailMessage.Subject = subject;
        mailMessage.Body = body;
        mailMessage.IsBodyHtml = isHtml;

        // 创建一个SmtpClient对象，并配置SMTP服务器信息
        SmtpClient smtpClient = new SmtpClient("smtp.example.com", 587);
        smtpClient.UseDefaultCredentials = false;
        smtpClient.Credentials = new NetworkCredential("your_username", "your_password");
        smtpClient.EnableSsl = true;

        // 发送邮件
        smtpClient.Send(mailMessage);
    }
}
