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

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。
