1、web.config文件配置，发送方邮箱账号、密码、邮箱类型

2、新建email文件

3、在email文件中填写必要代码

public class Email
{    
  public  const  string  WEB_SITE =  @"http://tasly.chinacloudsites.cn";
//public const string WEB_SITE = @"http://localhost:24295/";      
#region发邮件     
///<summary>
///发送邮件
///</summary>
///<param name="Email">发送的邮件地址，支持多个用英文;隔开</param>
///<param name="title">标题</param>
///<param name="body">内容</param>
///<returns></returns>

public static bool Send(string Email, string title, string body)
{
  try {
    string fromUser = System.Configuration.ConfigurationManager.AppSettings["fromUser"];       
    string password = System.Configuration.ConfigurationManager.AppSettings["password"];
    string address = System.Configuration.ConfigurationManager.AppSettings["address"];
    //创建MailMessage对象    //在ASP.NET利用本机的SMTP虚拟服务器的SMTP来发送邮件     

               
MailMessage Msg = new MailMessage();//        
Msg.From = new MailAddress("\"澳大利亚中医药学会官网\"<"+fromUser +">");
    foreach (var item in Email.Split( ';' ))
    {
      Msg.To.Add(item);
    }

    Msg.Subject = title;
    //邮件的主题
    Msg.IsBodyHtml =true;
    //指示邮件正文是否采用HTML文件格式.
    Msg.Body = body;
    //邮件内容
    SmtpClient objEmail = new SmtpClient(address);
    //SMTP服务器主机名，比如GMail的smtp.gmail.com
     objEmail.Credentials = new NetworkCredential (fromUser, password);
    //objEmail.Timeout = 30000;
    objEmail.EnableSsl = true ;
    //是否启用加密连接，GMail的邮箱必须用加密，其他不支持的邮箱用false
     objEmail.Send(Msg);
     return true ;
   }
    catch(Exception e)
    {
        return false;
    }

}
