如何在邮件正文消息中包含链接？

Question

我想发送一封带有超链接的电子邮件,我尝试发送没有链接的电子邮件,但是当我添加链接时,它会出错

这是代码:

MailMessage o = new MailMessage("f@hotmail.com", "f@hotmail.com", "KAUH Account Activation", "Hello, " + name + "\n Your KAUH Account about to activate click the link below to complete the actination process \n "+<a href=\"http://localhost:49496/Activated.aspx">login</a>);
NetworkCredential netCred = new NetworkCredential("f@hotmail.com", "****");
SmtpClient smtpobj = new SmtpClient("smtp.live.com", 587);
smtpobj.EnableSsl = true;
smtpobj.Credentials = netCred;
smtpobj.Send(o);

您需要为MailMessage类似的主体启用HTML,以便:

o.IsBodyHtml = true;

也许您应该选择另一个构造函数,以使代码更具可读性.也许这样的东西:

var mailMessage = new MailMessage();
mailMessage.From = new MailAddress("sender@domain.com", "Customer Service");
mailMessage.To.Add(new MailAddress("someone@domain.com"));
mailMessage.Subject = "A descriptive subject";
mailMessage.IsBodyHtml = true;
mailMessage.Body = "Body containing <strong>HTML</strong>";

更新 看起来你的字符串构建会给你带来麻烦.有时候,当把字符串放在一起(或者在调用时将它们连接起来)时,让所有引号都正确是很棘手的.当创建如电子邮件这样大的字符串时,有一些选项可以使它正确.

首先,常规字符串 - 缺点是难以阅读

string body = "Hello, " + name + "\n Your KAUH Account about to activate click the link below to complete the actination process \n <a href=\"http://localhost:49496/Activated.aspx">login</a>";

第二,逐字字符串 - 允许代码中的换行符提高可读性.注意开头的@字符,引号转义序列从更改\"为"".

string body = @"Hello, " + name + "\n Your KAUH Account about to
    activate click the link below to complete the actination process \n 
    <a href=""http://localhost:49496/Activated.aspx"">login</a>"

三,字符串构建器.在许多方面,这实际上是首选方式.

var body = new StringBuilder();
body.AppendFormat("Hello, {0}\n", name);
body.AppendLine(@"Your KAUH Account about to activate click 
    the link below to complete the actination process");
body.AppendLine("<a href=\"http://localhost:49496/Activated.aspx\">login</a>");
mailMessage.Body = body.ToString();
