asp調用C#編寫的DLL發送郵件

2013-11-15 12:48:58  來源: ASP編程 

  一直想寫一個asp能用發送郵件的服務器組件不過用VC太麻煩了一直都沒都手

  前兩天看一篇文章說是asp怎麼調用C#寫的DLL一試之下果然可以大喜這下用來寫一個發送郵件的東東簡單了吧

  呵呵非常簡單一會就弄好了不敢獨享先看代碼

   using System;

         /// <summary>  
         /// 返回錯誤信息  
         /// </summary>  
         public string Error

             get { return _error; }

         /// <summary>

         public void ClearErr()  
         {  
             _error = stringEmpty;  
         }  
     }  
} 
 

  說一下具體實現過程

  首先新建一個類庫項目打開項目屬性頁應用程序標簽設置程序集名稱為IMELS(當然這個你可以設置為你喜歡的名字)輸出類型為類庫如圖

  asp調用C#編寫的DLL發送郵件

  點擊程序集信息勾選使程序集COM可見如圖

  asp調用C#編寫的DLL發送郵件

  簽名標簽勾選為程序簽名如圖

  asp調用C#編寫的DLL發送郵件

  然後在選擇強名稱密鑰文件下拉列表中選擇密鑰文件如果沒有密鑰文件就選擇新建這裡我選擇新建如圖

  asp調用C#編寫的DLL發送郵件

  在密鑰文件名稱欄裡輸入密鑰的名稱你可以選擇為密鑰添加密碼保護它我這裡沒有使用密碼

  然後為項目添加一個類SendMail 代碼就如上了

  代碼完成後生成DLL文件把DLL放到D盤或別的什麼盤不過最好不要放在系統盤然後就是注冊了注冊C#寫的DLL是不能用regsvr要用regasm格式為regasm /codebase dDLLIMELSdll

  這樣DLL的編寫和注冊都已完成了下面就是應用了asp中調用方法如下

   <%   
  dim send   
  set send = ServerCreateObject(IMELSSendMail)   
    
  sendFrom =   
  sendFromName = 無問  
  sendSmtp =   
  sendUsername = 用戶名  
  sendPassword = 密碼  
 sendSubject = asp調用C#編寫的DLL發送郵件測試標題  
 sendContentType = html  
 sendCharset = gb  
 sendBody = asp調用C#編寫的DLL發送郵件測試正文  
 sendTo =   
 sendCC = 抄送地址  
 sendBCC = 密抄地址  
 sendSend()   
 ResponseWrite(sendError)   
 %>  
 

  好了大功告成!!
