利用System.Net.Mail和多线程实现邮件发送

对于邮件发送，一般来说，程序会响应超过1秒，这样对于用户体验来说，让用户等待的时间过长，而且发送的邮件越多时间就越长，所以这里我利用了线程的来处理邮件发送这种耗时的工作，废话不多说，直接上代码

 private string title;
    /// <summary>
    /// 发送标题
    /// </summary>
    public string Title
    {
        get { return title; }
        set { title = value; }
    }
    private string body;
    /// <summary>
    /// 发送内容，可以包含html
    /// </summary>
    public string Body
    {
        get { return body; }
        set { body = value; }
    }
    private List<string> toEmail = new List<string>();
    /// <summary>
    /// 发送给谁,可以多用户
    /// </summary>
    public List<string> ToEmail
    {
        get { return toEmail; }
        set { toEmail = value; }
    }
    private string toDis;
    /// <summary>
    /// 发送给谁的描述
    /// </summary>
    public string ToDis
    {
        get { return toDis; }
        set { toDis = value; }
    }
    private string fromDis;
    /// <summary>
    /// 发送人描述
    /// </summary>
    public string FromDis
    {
        get { return fromDis; }
        set { fromDis = value; }
    }

    public SendEmail(string title, string body, List<string> toEmail, string toDis, string fromDis)
    {
        this.title = title;
        this.body = body;
        this.toEmail = toEmail;
        this.toDis = toDis;
        this.fromDis = fromDis;
    }

    #region 邮件发送方法
    /// <summary>
    /// 利用线程来发送邮件，减少系统响应时间
    /// </summary>
    public void WebEmail()
    {
        try
        {
            Thread thread = new Thread(new ThreadStart(SendWebEmail));
            thread.Start();
        }
        catch
        {
            throw;
        }
    }

    public void SendWebEmail()
    {
        try
        {
            foreach (string toEmailName in this.ToEmail)
            {
                MailAddress from = new MailAddress(SendConfig.EmailName, this.FromDis);  //SendConfig.EmailName是发送邮件的邮箱名称
                MailAddress to = new MailAddress(toEmailName, this.ToDis);
                MailMessage msg = new MailMessage(from, to);
                msg.Priority = MailPriority.High;

                msg.Subject = this.Title;
                msg.Body = this.Body;
                msg.BodyEncoding = System.Text.Encoding.UTF8;
                msg.IsBodyHtml = true;

                SmtpClient smtp = new SmtpClient();
                smtp.Host = SendConfig.SMTP;  //SendConfig.SMTP是发送邮件的邮箱的SMTP
                smtp.UseDefaultCredentials = false;

                smtp.Credentials = new System.Net.NetworkCredential(SendConfig.EmailName, SendConfig.EmailPwd); //SendConfig.EmailPwd是发送邮件的邮箱的密码
                smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
                smtp.Send(msg);             
            }
        }
        catch (Exception e)
        {
            throw;
        }
    }
    #endregion

程序需要引用：

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

这两个命名空间
