直接贴代码了：

public static bool SendMail(string emailTo, string emailTitle, string emailContent ,  out string errorMessage, string[] filePath = null, string[] additionalHeaders = null)         {
               WebMail.SmtpServer = "smtp.gmail.com";//获取或设置要用于发送电子邮件的 SMTP 中继邮件服务器的名称。             WebMail.SmtpPort = 25;//发送端口             WebMail.EnableSsl = true;//是否启用 SSL GMAIL 需要 而其他都不需要 具体看你在邮箱中的配置             WebMail.UserName = "xxx";//账号名             WebMail.From = "xxx@gmail.com";//邮箱名             WebMail.Password = "xxx123456";//密码             WebMail.SmtpUseDefaultCredentials = true;//是否使用默认配置             errorMessage = null; try             {
                   WebMail.Send(to: emailTo, subject: emailTitle, body: emailContent, isBodyHtml: true, filesToAttach: filePath, additionalHeaders: additionalHeaders); return true;             } catch (Exception e)             {
                   errorMessage = e.Message; return false;             }         } public static bool SendMail(string emailTo, string emailTitle, string emailContent, out string errorMsg)         {
   bool flag = SendMail(emailTo, emailTitle, emailContent, out errorMsg); return flag;         }
