方法2:
這個是對於
EMAIL發送系統(C#+基於SMTP認證) 1.0
的改版這個初版是2002年11月寫的，過了一年半了，纔有人提意見，就修正了一下，由於後來作的項目一直用不上，也就沒有注意到
前段時間有網友反饋了一些問題，此次主要作了一些修正
1,text模式下發往163的郵件內容不見了
2,若是用outlook接收而不是在網上看郵件的話,會發現正文內容,但其後跟着一些亂碼.
3,一些新開通的郵箱收到的是亂碼，如*@126.com
4,修正了帶附件的郵件，打開附件時內容混亂的問題
感謝 Lion互動網絡論壇 的smhy8187和郵箱是grassdragon_china@yahoo.com.cn的朋友提供意見
歡迎你們提出修改建議，[注：]最好能把修改稿Mail給我一份，咱們共同窗習

//發送Mail，我重載了3次Send函數，可知足不一樣喜愛。
//1.若是全部的屬性都已經設置完畢，可直接使用無參數Send()
//Send();
//2.若是還沒有設置SMTP服務信息也可以使用以下形式設置
//Send("esmuser:esmpass@smtp.163.com:25")
//或者省略某些部分Send("esmuser:esmpass@smtp.163.com")或Send("smtp.163.com")
//3.或者將所有信息都寫在Send函數裏，不過這樣可讀性太差了
//Send(string smtpserver,string from,string fromname,string to,string toname,bool html,string subject,string body)
//開始發送
