C# 郵箱mail 發送類

 　　此類的功能包括發送郵件，郵箱格式是否正確，和在不發送郵件的情況下判斷郵箱用戶名和密碼是否正確，鑒於POP檢查郵箱用戶名和密碼出現錯誤情況返回結果的延遲，用異步線程解決此問題，見代碼

　　沒有牛B的設計模式，代碼精練精練實用，功能齊全，調用簡單 。。全全完完為碼農考慮

1 2 3 4 5 6 7 8 9 10 11 12 MailSmtp ms = new MailSmtp("smtp.qq.com","1215247044","xxxx"); //可選參數 ms.SetCC("[email protected]");//抄送可以多個 ms.SetBC("[email protected]");//暗送可以多個 ms.SetIsHtml(true);//默認:true ms.SetEncoding(System.Text.Encoding.UTF8);//設置格式 默認utf-8 ms.SetIsSSL(true);//是否ssl加密 默認為false //調用函數 bool isSuccess = ms.Send("[email protected]", "test", "[email protected]", "哈哈", "哈哈", Server.MapPath("~/Test.dll")); //輸出結果 Response.Write(ms.Result);
