  一直想写一个asp能用发送邮件的服务器组件,不过用VC太麻烦了,一直都没都手。

  前两天看一篇文章,说是asp怎么调用C#写的DLL,一试之下,果然可以,大喜,这下用来写一个发送邮件的东东简单了吧。

  呵呵,非常简单,一会就弄好了,不敢独享,先看代码:

  1 using System;  
  2 using System.Net.Mail;  
  3 using System.Text;  
  4  
  5 namespace IMELS  
  6 {  
  7     public class SendMail  
  8     {  
  9         public SendMail() { }  
 10  
 11         private string _to = string.Empty;  
 12  
 13         /// <summary>  
 14         /// 收件人地址,多个用“,”号隔开  
 15         /// </summary>  
 16         public string To  
 17         {  
 18             set { _to = value; }  
 19         }  
 20  
 21         private string _from = string.Empty;  
 22  
 23         /// <summary>  
 24         /// 发件人地址  
 25         /// </summary>  
 26         public string From  
 27         {  
 28             set { _from = value; }  
 29         }  
 30  
 31         private string _fromName = string.Empty;  
 32  
 33         /// <summary>  
 34         /// 发件人显示名称  
 35         /// </summary>  
 36         public string FromName  
 37         {  
 38             set { _fromName = value; }  
 39         }
