C#邮件发送类

最近业务需求需要用到自动推送邮件的，写了个邮件推送类方便调用
此类是静态类，直接调用类方法
此类可以多个接收人和多个抄送人，分别用“;”号隔开即可；

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


public class EmailSender
{
    /// <summary>
    /// 发送邮件
    /// </summary>
    /// <param name="fromAddress">发件人地址</param>
    /// <param name="toAddress">收件人地址（可多人，用“;”号隔开）</param>
    /// <param name="ccAddress">抄送人地址（可多人，用“;”号隔开）</param>
    /// <param name="fromName">发件人名称</param>
    /// <param name="passWord">发件授权码，非邮箱登陆密码</param>
    /// <param name="smtpAddress">smtp服务器地址</param>
    /// <param name="mailPort">发件箱端口</param>
    /// <param name="subjectTitle">邮件标题</param>
    /// <param name="body">邮件内容（支持html格式）</param>
    /// <param name="attachment">附件路径</param>
    public static bool SendEmail(string fromAddress, string toAddress, string ccAddress, string fromName, string passWord, string smtpAddress, int mailPort, string subjectTitle, string body, string attachment)
    {
        MailMessage mail = new MailMessage();

        //设置收件人地址，可多个收件人，收件人之间用“;”号隔开即可
        if (toAddress.Length > 0)
        {
            string[] toAdds = toAddress.Split(new char[] { ';' });
            foreach (string to in toAdds)
            {
                mail.To.Add(new MailAddress(to));
            }
        }

        //抄送人地址，可多个抄送人，抄送人之间用“;”号隔开即可
        if (ccAddress.Length > 0)
        {
            string[] ccAdds = ccAddress.Split(new char[] { ';' });
            foreach (string cc in ccAdds)
            {
                mail.CC.Add(new MailAddress(cc));
            }
        }

        //设置发件人邮箱及名称
        mail.From = new MailAddress(fromAddress, fromName);

        mail.Subject = subjectTitle;//邮件标题 
        mail.SubjectEncoding = Encoding.UTF8; //标题格式为UTF8 

        mail.Body = body;//邮件内容
        mail.BodyEncoding = Encoding.UTF8; //内容格式为UTF8 
        mail.IsBodyHtml = true;//设置邮件格式为html格式

        //如果有附件就执行邮件附件添加，如果没有就不用添加
        if (attachment.Length > 0)
        {
            mail.Attachments.Add(new Attachment(attachment));//添加附件
        }

        SmtpClient client = new SmtpClient();

        //发送邮箱信息
        client.Host = smtpAddress; //SMTP服务器地址 
        client.Port = mailPort; //SMTP端口，QQ邮箱填写587 

        client.EnableSsl = true; //启用SSL加密 （使用除QQ邮箱之外的最好关闭）

        //发件人邮箱账号，授权码
        client.Credentials = new System.Net.NetworkCredential(fromAddress, passWord);

        try
        {
            client.Send(mail); //发送邮件
            return true;
        }
        catch (Exception)
        {
            return false;
        }
    }
