C#实现邮件发送功能
- 发送邮件所用的核心知识点
- 微软封装好的MailMessage类:主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等)
- 微软封装好的SmtpClient类:主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等)
- SmtpClient主要进行了三层的封装:Socket --> TcpClient --> SmtpClient
- 具体代码请看如下所示:
public class MyEmail { private MailMessage mMailMessage; //主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等) private SmtpClient mSmtpClient; //主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等) private int mSenderPort; //发送邮件所用的端口号(htmp协议默认为25) private string mSenderServerHost; //发件箱的邮件服务器地址(IP形式或字符串形式均可) private string mSenderPassword; //发件箱的密码 private string mSenderUsername; //发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello) private bool mEnableSsl; //是否对邮件内容进行socket层加密传输 private bool mEnablePwdAuthentication; //是否对发件人邮箱进行密码验证 ///<summary> /// 构造函数 ///</summary> ///<param name="server">发件箱的邮件服务器地址</param> ///<param name="toMail">收件人地址(可以是多个收件人,程序中是以“;"进行区分的)</param> ///<param name="fromMail">发件人地址</param> ///<param name="subject">邮件标题</param> ///<param name="emailBody">邮件内容(可以以html格式进行设计)</param> ///<param name="username">发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello)</param> ///<param name="password">发件人邮箱密码</param> ///<param name="port">发送邮件所用的端口号(htmp协议默认为25)</param> ///<param name="sslEnable">true表示对邮件内容进行socket层加密传输,false表示不加密</param> ///<param name="pwdCheckEnable">true表示对发件人邮箱进行密码验证,false表示不对发件人邮箱进行密码验证</param> public MyEmail(string server, string toMail, string fromMail, string subject, string emailBody, string username, string password, string port, bool sslEnable, bool pwdCheckEnable) { try { mMailMessage = new MailMessage(); mMailMessage.To.Add(toMail); mMailMessage.From = new MailAddress(fromMail); mMailMessage.Subject = subject; mMailMessage.Body = emailBody; mMailMessage.IsBodyHtml = true; mMailMessage.BodyEncoding = System.Text.Encoding.UTF8; mMailMessage.Priority = MailPriority.Normal; this.mSenderServerHost = server; this.mSenderUsername = username; this.mSenderPassword = password; this.mSenderPort = Convert.ToInt32(port); this.mEnableSsl = sslEnable; this.mEnablePwdAuthentication = pwdCheckEnable; } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } public void Send() { try { if (mMailMessage != null) { mSmtpClient = new SmtpClient(); //mSmtpClient.Host = "smtp." + mMailMessage.From.Host; mSmtpClient.Host = this.mSenderServerHost; mSmtpClient.Port = this.mSenderPort; mSmtpClient.UseDefaultCredentials = false; mSmtpClient.EnableSsl = this.mEnableSsl; if (this.mEnablePwdAuthentication) { System.Net.NetworkCredential nc = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); //mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); //NTLM: Secure Password Authentication in Microsoft Outlook Express mSmtpClient.Credentials = nc.GetCredential(mSmtpClient.Host, mSmtpClient.Port, "NTLM"); } else { mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); } mSmtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; mSmtpClient.Send(mMailMessage); } } catch (Exception ex) { //m_CreateErrorLogTxt("程序池(Email)通知", "邮件发送失败", ex.Message); } } }
