C# 发送邮件整理,包括控制台程序、WPF、WebForm 及 ASP.NET MVC

  发送邮件使用SMTP服务器,有两种方案,一种是使用IIS的SMTP功能;另一种是直接使用邮件供应商的SMTP,比如Gmail、Sina、QQ等,使用这些SMTP服务器必须得注册帐号,一般可以直接用邮箱及密码,但是有些邮箱必须开启POP3/SMTP服务才可以,比如QQ邮箱默认是关闭的,可以在“设置”->“账户”里面找到。我今天整理的都是用的第二种。

  早期的.NET版本用的是 System.Web.Mail 类提供的功能来发邮件;2.0版本推出了 System.Net.Mail 类来代替 System.Web.Mail ,但是我在 WebForm 里面使用的时候用System.Net.Mail 老是触发异常,后来改用 System.Web.Mail 才成功了,可以看下我代码里的区别;ASP.NET MVC 3 提供了 WebMail 类来发送邮件,更加方便。

  控制台程序、WPF、WebForm 及 ASP.NET MVC 我都测试了一下,控制台程序和 WPF 都用了 System.Net.Mail ,WebForm 和 ASP.NET MVC 都可以用 System.Web.Mail ,而 ASP.NET MVC 3 直接用 WebMail 更方便。下面我把代码分别贴出来。

  控制台程序:

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Net.Mail;//添加引用
 6   
 7 namespace SendEmail
 8 {
 9     class Program
10     {
11         static void Main(string[] args)
12         {
13             Program p = new Program();
14             bool flag = p.SendEmail();
15             if (flag)
16             {
17                 Console.Write("Success !");
18             }
19               
20             Console.Read();
21         }
22   
23         public bool SendEmail()
24         {
25             MailMessage msg = new MailMessage();
26             msg.To.Add("1234567@qq.com");//邮件接收者的帐号
27             msg.From = new MailAddress("1234567@qq.com", "nickname", System.Text.Encoding.UTF8);//发送邮件的帐号及显示名称和字符编码
28             msg.Subject = "Subject";//邮件标题 
29             msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码 
30             msg.Body = "Content";//邮件内容 
31             msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码 
32             msg.IsBodyHtml = false;//是否是HTML邮件 
33             msg.Priority = MailPriority.High;//邮件优先级
34   
35             SmtpClient client = new SmtpClient();
36             client.Credentials = new System.Net.NetworkCredential("1234567@qq.com", "password");//注册的邮箱和密码,就QQ邮箱而言,如果设置了独立密码,要用独立密码代替密码             
37             client.Host = "smtp.qq.com";//QQ邮箱对应的SMTP服务器
38             object userState = msg;
39             try
40             {
41                 client.SendAsync(msg, userState);
42                 return true;
43             }
44             catch (Exception ex)
45             {
46                 Console.WriteLine(ex.Message);
47                 return false;
48             }
49         }
50     }
51 }

MVC:

 3             WebMail.SmtpServer = "smtp.qq.com";
 4             WebMail.SmtpPort = 25;//端口号,不同SMTP服务器可能不同,可以查一下
 5             WebMail.EnableSsl = false;//禁用SSL
 6             WebMail.UserName = "1234567@qq.com";
 7             WebMail.Password = "password";
 8             WebMail.From = "1234567@qq.com";
 9             WebMail.Send("1234567@qq.com","Subject",“Content");
10         }
11         catch (Exception)
12         {
13            
14         }
