C#實現郵件發送功能

• 發送郵件所用的核心知識點 

•   微軟封裝好的MailMessage類：主要處理發送郵件的內容（如：收發人地址、標題、主體、圖片等等）
•   微軟封裝好的SmtpClient類：主要處理用smtp方式發送此郵件的配置信息（如：郵件服務器、發送端口號、驗證方式等等）
•   SmtpClient主要進行了三層的封裝：Socket --> TcpClient --> SmtpClient

• 具體代碼請看如下所示：　　

public class MyEmail
    {
        private MailMessage mMailMessage;   //主要處理發送郵件的內容（如：收發人地址、標題、主體、圖片等等）
        private SmtpClient mSmtpClient; //主要處理用smtp方式發送此郵件的配置信息（如：郵件服務器、發送端口號、驗證方式等等）
        private int mSenderPort;   //發送郵件所用的端口號（htmp協議默認為25）
        private string mSenderServerHost;    //發件箱的郵件服務器地址（IP形式或字符串形式均可）
        private string mSenderPassword;    //發件箱的密碼
        private string mSenderUsername;   //發件箱的用戶名（即@符號前面的字符串，例如：[e-mail]，用戶名為：hello）
        private bool mEnableSsl;    //是否對郵件內容進行socket層加密傳輸
        private bool mEnablePwdAuthentication;  //是否對發件人郵箱進行密碼驗證
