本文实例讲述了C#实现的自定义邮件发送类。分享给大家供大家参考，具体如下：
using System; using System.Collections.Generic; using System.Text; using System.Net; using System.Net.Mail; using System.Net.Mime; namespace ConsoleApplication1 { /// <summary> /// 发送邮件类 的摘要说明 /// </summary> class SendMail { #region 数据成员 //收件人地址 private string m_To = ""; //发件人地址 private string m_From = ""; //邮件标题 private string m_Subject = ""; //邮件正文 private string m_Body = ""; //发送服务器名或地址 private string m_Host = ""; //发件人用户名 private string m_UserName = ""; //发件人密码 private string m_Password = ""; //邮件附件 private string m_File = ""; #endregion #region 构造函数 /// <summary> /// 构造函数重载 /// </summary> /// <param name="to">收件人地址</param> /// <param name="from">发件人地址</param> /// <param name="subject">邮件标题</param> /// <param name="body">邮件正文</param> /// <param name="host">发送邮件服务器名或地址</param> /// <param name="userName">发件人用户名</param> /// <param name="password">发件人密码</param> public SendMail(string to, string from, string subject, string body, string host, string userName, string password, string fileName) { m_To = to; m_From = from; m_Subject = subject; m_Body = body; m_Host = host; m_UserName = userName; m_Password = password; m_File = fileName; } #endregion #region 数据属性 //收件人地址 public string TO { get { return m_To; } set { m_To = value; } } //发件人地址 public string From { get { return m_From; } set { m_From = value; } } //邮件标题 public string Subject { get { return m_Subject; } set { m_Subject = value; } } //邮件正文 public string Body { get { return m_Body; } set { m_Body = value; } } //服务器地址（名） public string Host { get { return m_Host; } set { m_Host = value; } } //发件人的用户名 public string UserName { get { return m_UserName; } set { m_UserName = value; } } //发件人的密码 public string Password { get { return m_Password; } set { m_Password = value; } } //邮件附件 public string File { get { return m_File; } set { m_File = value; } } #endregion /// <summary> /// 发送邮件 /// </summary> /// <returns>发送是否成功</returns> public bool Send() { try { //获取所有的收件人地址 char[] ch = { ',' }; string[] address = m_To.Split(ch); MailAddressCollection allAddress = new MailAddressCollection(); for (int i = 0; i < address.Length; i++) { //收件人地址 MailAddress toAddress = new MailAddress(address[i]); allAddress.Add(toAddress); //发件人地址 MailAddress fromAddress = new MailAddress(m_From); //定义邮件消息 MailMessage msg = new MailMessage(fromAddress, toAddress); //邮件标题 msg.Subject = m_Subject; //邮件正文 msg.Body = m_Body; //获取所有邮件附件 char[] cr = { ';' }; string[] file = m_File.Split(cr); for (int n = 0; n < file.Length; n++) { if (file[n] != "") { //附件对象 Attachment data = new Attachment(file[n], MediaTypeNames.Application.Octet); //附件资料 ContentDisposition disposition = data.ContentDisposition; disposition.CreationDate = System.IO.File.GetCreationTime(file[n]); disposition.ModificationDate = System.IO.File.GetLastWriteTime(file[n]); disposition.ReadDate = System.IO.File.GetLastAccessTime(file[n]); //加入邮件附件 msg.Attachments.Add(data); } } //使用简单邮件传输协议来传送邮件 SmtpClient sendMail = new SmtpClient(); //发送邮件的服务器名或地址 sendMail.Host = m_Host; //验证发件人的身份 sendMail.Credentials = new NetworkCredential(m_UserName, m_Password); //处理待发送邮件的方法 sendMail.DeliveryMethod = SmtpDeliveryMethod.Network; //发送邮件 sendMail.Send(msg); } return true; } catch (Exception ex) { return false; } } } }
希望本文所述对大家C#程序设计有所帮助。
