c#发送邮件功能

需要引用using System.Net.Mail;

方法如下：

public class Mail
{
/// <summary>
/// 发送电子邮件
/// </summary>
/// <param name="MessageFrom">发件人邮箱地址</param>
/// <param name="MessageTo">收件人邮箱地址</param>
/// <param name="MessageSubject">邮件主题</param>
/// <param name="MessageBody">邮件内容</param>
/// <returns></returns>
public static bool Send(MailAddress MessageFrom, string MessageTo, string MessageSubject, string MessageBody)
{
MailMessage message = new MailMessage();

message.From = MessageFrom;
message.To.Add(MessageTo); //收件人邮箱地址可以是多个以实现群发
message.Subject = MessageSubject;
message.Body = MessageBody;
message.IsBodyHtml = false; //是否为html格式
message.Priority = MailPriority.High; //发送邮件的优先等级

SmtpClient sc = new SmtpClient();
sc.Host = "smtp.163.com"; //指定发送邮件的服务器地址或IP
sc.Port = 25; //指定发送邮件端口

//测试账号：zwtest2012@163.com/zwtest20122012 ,随便注册的一个163账号要是自己的可以填自己的
sc.Credentials = new System.Net.NetworkCredential("zwtest2012@163.com", "zwtest20122012"); //指定登录服务器的用户名和密码(发件人的邮箱登陆密码)

try
{
sc.Send(message); //发送邮件
}
catch(Exception ex)
{
//throw(ex);

ExcelDBA.WriteLog("----------------------------");//日志小分割
ExcelDBA.WriteLog("发送邮件到["+MessageTo.ToString()+"]失败!");
ExcelDBA.WriteLog("错误信息:"+ex.Message.ToString());
return false;
}
return true;

}

}

调用如下:

protected void Button1_Click(object sender, EventArgs e)
{
MailAddress MessageFrom = new MailAddress("zwtest2012@163.com"); //发件人邮箱地址 ,与方法里面的发送账号必须一致
string MessageTo = "abc@qq.com"; //收件人邮箱地址
string MessageSubject = "邮件标题标题"; //邮件主题
string MessageBody = "这里是邮件内容内容内容。"; //邮件内容

if (Mail.Send(MessageFrom, MessageTo, MessageSubject, MessageBody))
{
Response.Write("发送邮件成功111" + DateTime.Now.ToString());
}
else
{
Response.Write("发送邮件失败222" + DateTime.Now.ToString());
}

}
