C#利用System.Net发送邮件(带 抄送、密送、附件、html格式的邮件)

net2.0后,C#可以利用System.Net发送邮件了。

代码整理如下:

 3. 增加IProcessMessage类,定义了一个消息方法,用于消息传递

调用是按照需求,自由设置参数。

 1 using LeeStudio.Basic;
 2 
 3 private void SendEmail()
 4 {
 5 #region 最简设置 
 6 //SendEmail se = new SendEmail("*****@****.com", "****@163.com", "title", "body"); 
 7 //se.SetSmtp("password", "smtp.163.com"); //必须在所有参数设置完后调用此方法 
 8 #endregion
 9 
10 #region 完全设置 
11 //string toAddresses = "***@**.**,***@**.**"; 
12 //string toNames = "frank,lee";
13 
14 //SendEmail se = new SendEmail("to@**.**", "from@**.**", "toname", "fromname","title", "body", false); 
15 //se.SetMoreToAddress("to@**.**", "toName"); 
16 //se.SetCarbonCopyFor("cc@**.**"); 
17 //se.SetBlindCarbonCopyFor("bcc@**.**");
18 
19 //string filePath = Request.PhysicalApplicationPath + "/file/SendEmail.txt"; 
20 //se.Attachments(filePath); 
21 //filePath = Request.PhysicalApplicationPath + "/file/RTF文件.docx"; 
22 //se.AttachmentsForRTF(filePath); 
23 //se.SetSmtp("email", "password", "smtp", 25, true, System.Net.Mail.MailPriority.Normal); //必须在所有参数设置完后调用此方法 
24 #endregion
25 }

 

遗留问题:

当有多个收件人/抄送者/密送者时,如何快速处理?之前的做法是让用户输入字符串,再将字符串一一对应匹配,代码如下:

 1 /// <summary>  
 2 /// 将邮件地址和名称加入到锯齿数组中  
 3 /// </summary>  
 4 /// <param name="addrs">邮件地址(多个以,号分开)</param>  
 5 /// <param name="names">名称(多个以,号分开)</param>  
 6 /// <returns>地址和名称数组</returns>  
 7 private string[][] SetNameList(string addrs, string names)
 8 {
 9     string[][] result = new string[2][];
10 
11     string[] addr = addrs.Split(',');
12     string[] name = names.Split(',');
13     result[0] = new string[addr.Length];
14     result[1] = new string[name.Length];
15 
16     for (int i = 0; i < addr.Length; i++)
17         result[0][i] = addr[i];
18     for (int i = 0; i < name.Length; i++)
19         result[1][i] = name[i];
20 
21     return result;
22 }

 

首先这个方法就很奇葩,其次,只要用户输入的个数不对应,又要做一堆的异常处理。
