C# Send Mail System.Net.Mail

It is very simple to realize the function of sending emails in C#. Microsoft has already done most of the things for us. Not much to say, the code:

  1  public  class Email
   2          {
   3              ///  <summary> 
  4              /// Sender
   5              ///  </summary> 
  6              public  string mailFrom { get ; set ; }
   7  
  8              ///  <summary> 
  9              /// Receive Person
 10              ///  </summary> 
11              public  string [] mailToArray { get ; set ; }
 12  
13              ///  <summary> 
14              /// CC
 15             /// </summary>
 16             public string[] mailCcArray { get; set; }
 17 
 18             /// <summary>
 19             /// 标题
 20             /// </summary>
 21             public string mailSubject { get; set; }
 22 
 23             /// <summary>
 24             /// 正文
 25             /// </summary>
 26             public string mailBody { get; set; }
 27 
28              ///  <summary>

 30              ///  </summary> 
31              public  string mailPwd { get ; set ; }
 32  
33              ///  <summary> 
34              /// SMTP mail server
 35              / //  </summary> 
36              public  string host { get ; set ; }
 37  
38              ///  <summary> 
39              /// Whether the text is in html format
 40              ///  </summary> 
41              public  boolisbodyHtml { get ; set ; }
 42  
43              ///  <summary> 
44              /// attachments
 45              ///  </summary> 
46              public  string [] attachmentsPath { get ; set ; }
 47  
48              public  bool Send()
 49              {
 50                  // Initialize the MailAddress instance with the specified email address 
51                  MailAddress maddr = new MailAddress(mailFrom);
 52                  // Initialize the MailMessage instance 
53                 MailMessage myMail = new MailMessage();
 54  
55  
56                  // Add mail address to recipient address collection 
57                  if (mailToArray != null )
 58                  {
 59                      for ( int i = 0 ; i < mailToArray.Length; i++ )
 60                      {
 61                          myMail.To.Add(mailToArray[i].ToString());
 62                      }
 63                  }
 64  
65                  // Add email address to CC recipient address collection 
66                  if (mailCcArray !=null )
 67                  {
 68                      for ( int i = 0 ; i < mailCcArray.Length; i++ )
 69                      {

 71                      }
 72                  }
 73                  // sender address 
74                  myMail.From = maddr;
 75  
76                  // The subject of the email is 
77                  myMail.Subject = mailSubject;
 78  
79                  // The encoding used for the subject of the email is 
80                 myMail.SubjectEncoding = Encoding.UTF8;
 81  
82                  // email body 
83                  myMail.Body = mailBody;
 84  
85                  // encoding of the email body 
86                  myMail.BodyEncoding = Encoding.Default;
 87  
88                  myMail.Priority = MailPriority.High;
 89  
90                  myMail.IsBodyHtml = isbodyHtml;
 91  
92                  // Add attachments if there are attachments 
93                  try 
94                  {
 95                      if (attachmentsPath != null && attachmentsPath.Length > 0)
 96                     {
 97                         Attachment attachFile = null;
 98                         foreach (string path in attachmentsPath)
 99                         {
100                             attachFile = new Attachment(path);
101                             myMail.Attachments.Add(attachFile);
102                         }
103                     }
104                 }
105                 catch (Exception err)
106                  {
 107                      throw  new Exception( " Error adding attachment: " + err);
 108                  }
 109  
110                  SmtpClient smtp = new SmtpClient();
 111                  // Specify the sender's email address and password to verify the sender's identity 
112                  smtp.Credentials = new System.Net.NetworkCredential(mailFrom, mailPwd);
 113  
114  
115                  // Set SMTP mail server 
116                  smtp.Host = host;
 117                  smtp.EnableSsl = true ;
118                  try 
119                  {
 120                      // Send mail to SMTP mail server 
121                      smtp.Send(myMail);
 122                      return  true ;
 123  
124                  }
 125                  catch (System.Net.Mail.SmtpException)
 126                  {
 127                      return  false ;
 128                  }
 129  
130              }
 131          }

With the above class, just call Send to access it directly

1 Email email = new Email();         
 2 email.mailFrom = account number;         
 3 email.mailPwd = password;
 4 email.mailSubject = titile; // title 
5 email.mailBody = content; // body 
6 email.isbodyHtml = true ;     // Whether it is HTML 
7 email.host = mailbox host; // If it is QQ mailbox: smtp:qq.com, and so on 
8 email.mailToArray = new  string [] { emailaddress }; // Receiver mail collection 
9 email .mailCcArray = new  string[] { }; // CC email collection   
10 email.Send();

At this point, the mail sending function is completed, let's try it now
