本文实例为大家介绍了C#邮件群发通用类，供大家参考，具体内容如下
public static class Email
{
/// <summary>
/// 发件人
/// </summary>
public static string mailFrom { get ; set ; }
/// <summary>
/// 收件人
/// </summary>
public static string [] mailToArray { get ; set ; }
/// <summary>
/// 抄送
/// </summary>
public static string [] mailCcArray { get ; set ; }
/// <summary>
/// 标题
/// </summary>
public static string mailSubject { get ; set ; }
/// <summary>
/// 正文
/// </summary>
public static string mailBody { get ; set ; }
/// <summary>
/// 发件人密码
/// </summary>
public static string mailPwd { get ; set ; }
/// <summary>
/// SMTP邮件服务器
/// </summary>
public static string host { get ; set ; }
/// <summary>
/// 邮件服务器端口
/// </summary>
public static int port { get ; set ; }
/// <summary>
/// 正文是否是html格式
/// </summary>
public static bool isbodyHtml { get ; set ; }
/// <summary>
/// 附件
/// </summary>
public static string [] attachmentsPath { get ; set ; }
public static bool Send()
{
//使用指定的邮件地址初始化MailAddress实例
MailAddress maddr = new MailAddress(mailFrom);
//初始化MailMessage实例
MailMessage myMail = new MailMessage();
//向收件人地址集合添加邮件地址
if (mailToArray != null )
{
for ( int i = 0; i < mailToArray.Length; i++)
{
myMail.To.Add(mailToArray[i].ToString());
}
}
//向抄送收件人地址集合添加邮件地址
if (mailCcArray != null )
{
for ( int i = 0; i < mailCcArray.Length; i++)
{
myMail.CC.Add(mailCcArray[i].ToString());
}
}
//发件人地址
myMail.From = maddr;
//电子邮件的标题
myMail.Subject = mailSubject;
//电子邮件的主题内容使用的编码
myMail.SubjectEncoding = Encoding.UTF8;
//电子邮件正文
myMail.Body = mailBody;
//电子邮件正文的编码
myMail.BodyEncoding = Encoding.Default;
//电子邮件优先级
myMail.Priority = MailPriority.High;
//电子邮件不是html格式
myMail.IsBodyHtml = isbodyHtml;
//在有附件的情况下添加附件
try
{
if (attachmentsPath != null && attachmentsPath.Length > 0)
{
Attachment attachFile = null ;
foreach ( string path in attachmentsPath)
{
attachFile = new Attachment(path);
myMail.Attachments.Add(attachFile);
}
}
}
catch (Exception err)
{
throw new Exception( "在添加附件时有错误:" + err.Message);
}
SmtpClient client = new SmtpClient();
//指定发件人的邮件地址和密码以验证发件人身份
client.Credentials = new NetworkCredential(mailFrom, mailPwd);
//设置SMTP邮件服务器
//client.Host = "smtp." + myMail.From.Host;
client.Host = host;
//SMTP邮件服务器端口
client.Port = port;
//是否使用安全连接
//client.EnableSsl = true;
try
{
//将邮件发送到SMTP邮件服务器
client.Send(myMail);
return true ;
}
catch (SmtpException ex)
{
string msg = ex.Message;
return false ;
}
}
