Asp.Net给多用户发邮件完整代码(已在163通过测试)

发信类 sendMail.cs

using System.Data;


using System.Configuration;


using System.Web;


using System.Web.Security;


using System.Web.UI;

/**//// <summary>

public class sendMail

public sendMail()




...{


//


// TODO: 在此处添加构造函数逻辑

}




/**//// <summary>

/// <param name="from">发送人邮件地址</param>

public static bool Send(string from, string to, string subject, bool isBodyHtml, string body, string smtpHost, string userName, string password)




...{


string[] ts = to.Split(',');


bool isSuccess = true;


foreach (string t in ts)




...{


try




...{


MailMessage mm = new MailMessage();


mm.From = new MailAddress(from);




mm.To.Add(new MailAddress(t.Trim()));




mm.Subject = subject;


mm.IsBodyHtml = isBodyHtml;


mm.Body = body;




SmtpClient sc = new SmtpClient();


sc.Host = smtpHost;




sc.UseDefaultCredentials = true;//winform中不受影响，asp.net中，false表示不发送身份严正信息


//smtpClient.EnableSsl = true;//如果服务器不支持ssl则报，服务器不支持安全连接 错误


sc.Credentials = new System.Net.NetworkCredential(userName, password);


sc.DeliveryMethod = SmtpDeliveryMethod.Network;




sc.Send(mm);


}


catch




...{


isSuccess = false;


}


}


return isSuccess;


}


}





调用发信函数




if (sendMail.Send("ycyangcai@163.com", "ycyangcai@163.com", "subject", true, "body", "smtp.163.com", "yangcai", "yangcai"))




...{


Response.Write("ok");


}


else




...{


Response.Write("no");


}
