c#发送邮件.net1.1和.net2.0中的两个方法

.net1.1

using System.Web.Mail;

使用：

SendSMTPEMail("100.100.100.100", "someone@xxx.com", "xxxx", "someone@xxx.com", "webtest", TextBox1.Text, null, null);

方法体：

public void SendSMTPEMail(string strSmtpServer, string strFrom, string strFromPass, string strto, string strSubject, string strBody, string bcc, string cc)

{

System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage();

mail.BodyFormat = MailFormat.Html;

mail.From = strFrom;

mail.To = strto; //多个收件人之间用分号分割

mail.Bcc = bcc;

mail.Cc = cc;

mail.Subject = "mail test!!!";

mail.Body = TextBox1.Text;

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", strFrom);

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", strFromPass);

System.Web.Mail.MailAttachment attachment = new System.Web.Mail.MailAttachment("c:\\log.log");

mail.Attachments.Add(attachment);

SmtpMail.SmtpServer = strSmtpServer;

SmtpMail.Send(mail);

}

或

/// <summary>

/// 发送邮件

/// </summary>

/// <param name="to">收件人邮件地址</param>

/// <param name="from">发件人邮件地址</param>

/// <param name="subject">邮件主题</param>

/// <param name="body">邮件内容</param>

/// <param name="username">登录smtp主机时用到的用户名,注意是邮件地址'@'以前的部分</param>

/// <param name="password">登录smtp主机时用到的用户密码</param>

/// <param name="smtpHost">发送邮件用到的smtp主机</param>

public void Send(string to, string from, string subject, string body, string username, string password, string smtpHost)

{

MailMessage mail = new MailMessage();

mail.To = to;//设置收件人地址

mail.From = from;//设置发件人地址

mail.Subject = subject;//设置邮件主题

mail.BodyFormat = MailFormat.Html;//设置邮件以HTML格式发送

mail.Body = body;//设置邮件内容

//设置发送邮件时需要身份验证

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");

//设置登录邮件主机时的用户名，注意如果发件人地址是abc@def.com，则用户名是abc而不是abc@def.com

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", userName);

//设置登录SMTP主机的用户密码

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", password);

//设置发送邮件的SMTP主机

SmtpMail.SmtpServer = smtpHost;

//发送邮件，如果发送不成功会抛出异常

SmtpMail.Send(mail);

}

.net2.0

using System.Net.Mail;

使用：

SendSMTPEMail("100.100.100.100", "someone@xxx.com", "xxxx", "someone@xxx.com", "webtest", TextBox1.Text, null, null);

方法体：

public void SendSMTPEMail(string strSmtpServer, string strFrom, string strFromPass, string strto, string strSubject, string strBody)

{

System.Net.Mail.SmtpClient client = new SmtpClient(strSmtpServer);

client.UseDefaultCredentials = false;

client.Credentials = new System.Net.NetworkCredential(strFrom, strFromPass);

client.DeliveryMethod = SmtpDeliveryMethod.Network;

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(strFrom, strto, strSubject, strBody);

System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment("c:\\log.log");

message.Attachments.Add(attachment);

message.BodyEncoding = System.Text.Encoding.UTF8;

message.IsBodyHtml = true;

client.Send(message);
