一． 用Asp.net实现邮件系统
1
/**//// <summary>
2
/// 功能：实现在Web页面中发送Email
3
/// </summary>
4
private void SendMail()
5
{
6
MailMessage m = new MailMessage();
7
8
/**////发件人地址
9
m.From = tbFrom.Text;
10
11
/**////收件人地址
12
m.To = tbTo.Text;
13
14
/**////邮件主题
15
m.Subject = tbSubject.Text;
16
17
/**////邮件内容
18
m.Body = tbBody.Text;
19
20
/**////优先级
21
switch(ddlp.SelectedIndex)
22
{
23
case 0:
24
m.Priority = MailPriority.High;
25
break;
26
case 1:
27
m.Priority = MailPriority.Low;
28
break;
29
default:
30
m.Priority = MailPriority.Normal;
31
break;
32
}
33
34
/**////设置邮件格式
35
if(ddlp.SelectedIndex==0)
36
m.BodyFormat = MailFormat.Text;
37
else
38
m.BodyFormat = MailFormat.Html;
39
40
/**////设置服务器
41
if(tbServer.Text!="")
42
{
43
SmtpMail.SmtpServer = tbServer.Text;
44
}
45
46
/**////以下处理附件
47
string strFileName = FileSelect.PostedFile.FileName;
48
if(strFileName!="")
49
m.Attachments.Add(new MailAttachment(strFileName));
50
51
/**////发送邮件
52
SmtpMail.Send(m);
53
}
二． 利用Socket来接收邮件
1
/**//// <summary>

5

8
if(n==-1)
9

10
Response.Write("<script language='javascript'>alert('服务器连接错误！')</script>");
11
return;
12
}
13
ddlNew.Items.Clear();
14
for(int i=1;i<=n;i++)
15
ddlNew.Items.Add("第"+i.ToString()+"封邮件");
16
if(n>0)
17

18
MailMessage msg = pop.GetNewMessages(0);
19
if(msg!=null)
20
tbBody.Text = msg.Body;
21

三． 利用Socket来发送邮件
1
/**//// <summary>
2
/// 功能：利用Socket来发送邮件
3
/// </summary>
4
private void SocketSendMail()
5
{
6
SMTP smtp = new SMTP();
7
bool bSuccess = smtp.Send(tbSmtp.Text,25,tbSend.Text,tbReceive.Text,tbSubject.Text,tbBody.Text);
8
if(bSuccess)
9
Response.Write("<script language='javascript'>alert('邮件发送成功！')</script>");
10
else
11
Response.Write("<script language='javascript'>alert('邮件发送失败！')</script>");
12
}
SMTP类的实现如下：
1
/**//// <summary>
2
/// 发送邮件类
3
/// </summary>
4
public class SMTP
5
{
6
public SMTP()
{}
7
8
public bool Send(string strSmtpServer,int nPort,string strSend,string strReceive
9
,string strSubject,string strContent)
10
{
11
/**//// smtp服务器的IP地址
12
string smtpserver=strSmtpServer;
13
TcpClient tcpc = new TcpClient();
14
try
15
{
16
tcpc.Connect(smtpserver, nPort);
17
StreamReader sr ;
18
string strCmd;
19
sr = new StreamReader(tcpc.GetStream(),Encoding.Default);
20
21
/**////服务器连接成功以后，首先向服务器发送HeLlo命令
22
strCmd="HELO shaozhd";
23
SenSmtpCmd(tcpc,strCmd);
24
25
/**////然后向服务器发送信件的成员的信箱
26
strCmd="mail from:"+ strSend;
27
SenSmtpCmd(tcpc,strCmd);
28
29
/**////向服务器发送收件人的信箱
30
strCmd="rcpt to:" + strReceive;
31
SenSmtpCmd(tcpc,strCmd);
32
33
/**////所有的准备工作都已经作好了,下面开始进行邮件的部分
34
strCmd="data";
35
SenSmtpCmd(tcpc,strCmd);
36
37
/**////邮件内容
38
strCmd="Date: 1234567/r/n";
39
strCmd=strCmd+"From: " + strSend +"/r/n";
40
strCmd=strCmd+"To: " + strReceive +"/r/n";
41
strCmd=strCmd+"Subject: " + strSubject +"/r/n/r/n";
42
strCmd=strCmd + strContent +"/r/n/r/n";
43
SenSmtpCmd(tcpc,strCmd);
44
strCmd="/r/n./r/n";
45
SenSmtpCmd(tcpc,strCmd);
46
47
/**////最后 关闭与smtp 服务器的连接
48
tcpc.Close();
49
return true;
50
}
51
catch
52
{
53
return false;
54
}
55
}
56
57
/**//// <summary>
58
/// 发送SMTP命令
59
/// </summary>
60
/// <param name="tcpc"></param>
61
/// <param name="strCmd"></param>
62
void SenSmtpCmd(TcpClient tcpc,String strCmd)
63
{
64
65
byte[] arrCmd;
66
string strRet;
67
StreamReader sr;
68
Stream s;
69
s=tcpc.GetStream();
70
strCmd = strCmd + "/r/n";
71
arrCmd= Encoding.Default.GetBytes(strCmd.ToCharArray());
72
s=tcpc.GetStream();
73
s.Write(arrCmd, 0, strCmd.Length);
74
75
/**////以下用于程序调试，显示服务器回应信息
76

77
strRet=sr.ReadLine();
78
return;
79
}
