使用腾讯的邮箱：QQ邮箱默认的SMTP服务是关闭的，要自己去开通

在web.config中进行设置

1 <appSettings>
2         <add key="MailServer" value="smtp.qq.com"/>
3         <add key="MailUsername" value="[email protected]"/>
4         <add key="MailPassword" value="****"/> 
5         <add key="MailFrom" value="[email protected]"/>
6         <add key="EnableErrorLogEmail" value="true"/>
7         <add key="ErrorLogEmail" value="[email protected]"/>
8         
9 </appSettings>

然后写了一个类来取这些数据：BalloonShopConfiguration.cs

 1 public static class BalloonShopConfiguration
 2 {
 3     
 4     //缓存链接字符串
 5     private static string dbConnectionString;
 6     //缓存数据提供器名称
 7     private static string dbProviderName;
 8     static BalloonShopConfiguration()
 9     {
10         dbConnectionString = ConfigurationManager.ConnectionStrings["connectionStrings"].ConnectionString;
11         dbProviderName = ConfigurationManager.ConnectionStrings["connectionStrings"].ProviderName;
12 
13     }
14     //返回针对connectionStrings的数据库链接字符串
15     public static string DbConnectionString{
16        get
17         {
18            return dbConnectionString;
19        }
20     }
21     //返回数据提供器名称
22     public static string DbProviderName {
23         get {
24             return dbProviderName;
25         }
26     }
27     //返回邮件服务器地址
28     public static string MailServer {
29         get {
30             return ConfigurationManager.AppSettings["MailServer"];
31         }
32     }
33     //返回电子邮件用户名
34     public static string MailUsername {
35         get {
36             return ConfigurationManager.AppSettings["MailUsername"];
37         }
38     }
39     //返回电子邮件密码
40     public static string MailPassword {
41         get {
42             return ConfigurationManager.AppSettings["MailPassword"];
43         }
44     }
45     //返回电子邮件发件人
46     public static string MailFrom
47     {
48         get
49         {
50             return ConfigurationManager.AppSettings["MailFrom"];
51         }
52     }
53     //是否发送错误日志
54     public static bool EnableErrorLogEmail
55     {
56         get {
57             return bool.Parse(ConfigurationManager.AppSettings["EnableErrorLogEmail"]); 
58         }
59     }
60     //返回发送错误日志的邮箱
61     public static string ErrorLogEmail
62     {
63         get {
64             return ConfigurationManager.AppSettings["ErrorLogEmail"];
65         }
66     }
67 }

通用的发送邮件的方法：SendMail

 1 public static void SendMail(string from ,string to,string title,string body) {
 2         //设置邮件客户端
 3         SmtpClient mailclient = new SmtpClient(BalloonShopConfiguration.MailServer);
 4         //设置验证信息（针对需要身份验证smtp）
 5         mailclient.Credentials = new NetworkCredential(BalloonShopConfiguration.MailFrom, BalloonShopConfiguration.MailPassword);
 6         //创建电子邮件
 7         MailMessage message = new MailMessage(from, to, title, body);
 8         
 9         //发送邮件
10         mailclient.Send(message);
11     }

在发生错误时，try{}catch{},在catch中调用发送错误日志的方法，将错误日志通过邮件发送到管理员邮箱（[email protected]），该方法在类Utilities中

 1 public static void ErrorLog(Exception ex) { 
 2     //获取当前时间
 3         string datetime = DateTime.Now.ToLongDateString() + ",at" + DateTime.Now.ToShortTimeString();
 4         //存储错误信息
 5         string ErrorMessage = "错误发生在" + datetime;
 6         //获取错误发生的页面
 7         System.Web.HttpContext context = HttpContext.Current;
 8         ErrorMessage += "\n\n 发生错误时请求的原始URL:" + context.Request.RawUrl;
 9         //构建错误消息
10         ErrorMessage += "\n\n 错误消息内容："+ex.Message;
11         ErrorMessage +="\n\n 错误发生的对象："+ex.Source;
12         ErrorMessage +="\n\n 错误发生的方法："+ex.TargetSite;
13         ErrorMessage += "\n\n 错误发生时调用堆栈上直接帧的字符串表示形式" + ex.StackTrace;
14 
15         if(BalloonShopConfiguration.EnableErrorLogEmail){
16             string from = BalloonShopConfiguration.MailFrom;
17             string to = BalloonShopConfiguration.ErrorLogEmail;
18             string title = "BalloonShop has happed Error";
19             string body = ErrorMessage;
20             SendMail(from, to, title, body);
21         }
22     }

在web.config中<system.web>设置：

1 <!--发生错误时会跳到自定义页面，mode="on"时，发送错误时本机也显示oops.aspx页面,
2           如果mode为：RemoteOnly，在远程访问机器上访问时显示Oops.aspx页面，在本机显示错误详细信息-->
3         <customErrors mode="RemoteOnly" defaultRedirect="OoPs.aspx"></customErrors>

其他人写的方法：

代码：

1 163邮箱 HOST:smtp.163.com

public static string CreateTimeoutTestMessage(string server)
        {
string Success = "发送成功";
try
            {
string _to = "[email protected]";
string _from = "[email protected]";
string _subject = "Using the new SMTP client.";
string _body = @"Using this new feature, you can send an e-mail message from an application very easily.";
                MailMessage message = new MailMessage();
                message.From = new MailAddress(_from);
//可以利用MailMessage.To.Add方法增加要发送的邮件地址
                message .To .Add (new MailAddress ("[email protected]"));
                message.To.Add(new MailAddress(_to));
                message.Subject = _subject;
                message.Body = _body;

//添加附件
                Attachment a = new Attachment(@"C:/Users/Administrator/Desktop/smtpclient.rar");
                message.Attachments.Add(a);
//设置邮箱的地址或IP
                SmtpClient client = new SmtpClient(server);
//设置邮箱端口，pop3端口:110, smtp端口是:25 
                client.Port = 25;

//设置超时时间
                client.Timeout = 9999;

//要输入邮箱用户名与密码
                
                client.Credentials = new NetworkCredential("[email protected]", "******");
                client.Send(message);
            }
catch (Exception ex)
            {
                Success = ex.ToString();
            }
return Success;
        }

2 QQ邮箱

QQ邮箱默认的SMTP服务是关闭的，要自己去开通。

HOST:smtp.qq.com

 1 try
 2             {
 3                 
 4                 SmtpClient client = new SmtpClient();
 5                 client.Host = "smtp.qq.com";
 6                 MailMessage mm = new MailMessage();
 7                 client.Port = 25;
 8                 
 9                 mm.From = new MailAddress("[email protected]");                
10                 mm.To.Add(new MailAddress("[email protected]"));
11                 mm.Subject = "Hello~!";
12                 mm.Body = "HIthere.here is a post ";
13                 mm.IsBodyHtml = false;
14                 mm.Priority = MailPriority.High;
15 
16                 client.Credentials = new NetworkCredential("[email protected]", "******");
17                 client .Send (mm);
18                
19 
20             }
21             catch (Exception ex)
22             {
23                 MessageBox.Show(ex.Message);
24             }
