概述：该文主要介绍了MailBee.NET Objects中发送包含纯文本和HTML格式主体的邮件，并添加.xls文档附加。欢迎您下载试用版进行运用！
在单行代码中快速发送电子邮件的最简单的方法是使用SMTP对象的QuickSend方法。在这种情况下，开发人员甚至不需要创建一个新的SMTP对象实例。只需要指定其基本属性（如From、To、Subject、Body等）：
| C#: MailBee.SmtpMail.Smtp.QuickSend("from@me.com", "to@you.com", "Subject", "Message Body"); |
| VB.NET: MailBee.SmtpMail.Smtp.QuickSend("from@me.com", "to@you.com", "Subject", "Message Body") |
开发人员还可以使用QuickSend方法发送带有附件的电子邮件，如下所示：
| C#: MailBee.SmtpMail.Smtp.QuickSend("From Me (Company Info)", "To you ", "Subject", "Plain text body", "HTML-formatted body", null, @"C:\My Documents\report.doc"); |
| VB.NET: MailBee.SmtpMail.Smtp.QuickSend("From Me (Company Info)", _ "To you ", _ "Subject", "Plain text body", _ "«html»HTML-formatted body«/html»", _ Nothing, "C:\My Documents\report.doc") |
开发人员可以直接使用一个SMTP对象的实例，该实例提供了广泛的方法和属性来调整消息发送的过程。C＃应用程序中的SMTP对象的新实例可以创建如下：
| C#: Smtp oMailer = new Smtp(); |
| VB.NET: Dim oMailer As New Smtp() |
如果SMTP服务器不需要任何身份验证，那么指定的主机名或相同的IP地址就可以连接到此SMTP服务器，如下所示：
| C#: oMailer.SmtpServers.Add("smtp.domain.com"); |
| VB.NET: oMailer.SmtpServers.Add("smtp.domain.com") |
或者
| C#: oMailer.SmtpServers.Add("127.0.0.1"); |
| VB.NET: oMailer.SmtpServers.Add("127.0.0.1") |
另一方面，如果SMTP服务器需要身份验证，开发人员应该确定该服务器上的帐户名称和相应的密码：
| C#: oMailer.SmtpServers.Add("smtp.domain.com","login","password"); |
| VB.NET: oMailer.SmtpServers.Add("smtp.domain.com","login","password") |
或者
| C#: oMailer.SmtpServers.Add("127.0.0.1","login","password"); |
| VB.NET: oMailer.SmtpServers.Add("127.0.0.1","login","password") |
然后，开发人员应确定邮件发件人的电子邮件地址，如下所示：
| C#: oMailer.From.AsString = "Dan Brown (Company Info)"; |
| VB.NET: oMailer.From.AsString = "Dan Brown (Company Info)" |
或者
| C#: oMailer.From.AsString = "Dan Brown "; |
| VB.NET: oMailer.From.AsString = "Dan Brown " |
或者
| C#: oMailer.From.AsString = "dan@domain.com"; |
| VB.NET: oMailer.From.AsString = "dan@domain.com" |
添加To、Cc、Bcc或Reply-To，开发人员应使用SMTP对象的相应属性，如下所示：
| C#: oMailer.To.AsString = "Bill Smith (Remarks), Kathy@mail.com "; oMailer.Cc.AsString = "Joe Black , Joseph "; oMailer.Bcc.AsString = "t.jay@domain.com, s.connor@domain.com"; oMailer.ReplyTo.AsString = "john@domain.com, Barbara Jones "; |
| VB.NET: oMailer.To.AsString = "Bill Smith (Remarks), Kathy@mail.com " oMailer.Cc.AsString = "Joe Black , Joseph " oMailer.Bcc.AsString = "t.jay@domain.com, s.connor@domain.com" oMailer.ReplyTo.AsString = "john@domain.com, Barbara Jones " |
要指定邮件主题，开发人员应使用SMTP对象的Subject属性，如下所示：
| C#: oMailer.Subject = "Test message"; |
| VB.NET: oMailer.Subject = "Test message" |
此外，邮件可能没有主题。
开发人员还应该确定信息的正文。如果是纯文本，开发人员应该使用BodyPlainText属性：| C#: oMailer.BodyPlainText = "This is a test e-mail message."; |
| VB.NET: oMailer.BodyPlainText = "This is a test e-mail message." |
如果开发人员要使用HTML格式的正文，那么应该设置BodyHtmlText属性：
| C#: oMailer.BodyHtmlText = @" Test HTML message. This is a test HTML mes-sage. "; |
| VB.NET: oMailer.BodyHtmlText = "Test HTML message. " & vbCrLf & _ "" & vbCrLf & _ "" & vbCrLf & _ "This is a test HTML mes-sage." & vbCrLf & _ " " & vbCrLf & _ "" & vbCrLf & _ "" |
开发人员也可以将这两种类型同时使用。在这种情况下，邮件客户端的设置会影响显示哪个正文。
要将任何文件附加到电子邮件中，开发人员应使用AddAttachment方法，该方法只需要开发人员指定此文件的完整路径。要添加多个附件，开发人员应重复调用AddAttachment方法，如下所示：| C#: oMailer.AddAttachment(@"C:\annual_reoprt.xls"); oMailer.AddAttachment(@"C:\deposits.doc"); |
| VB.NET: oMailer.AddAttachment("C:\annual_reoprt.xls") oMailer.AddAttachment("C:\deposits.doc") |
要发送信息，开发人员应调用SMTP对象的Send方法。由于此方法可能会引发异常，开发人员可以按如下方式处理这些异常：
| C#: try { oMailer.Send(); Console.WriteLine("The message has been successfully sent."); } catch (MailBeeSmtpRefusedRecipientException e) { Console.WriteLine("The following recipient was refused by SMTP server: " + e.RefusedRecipientEmail); } |
| VB.NET: Try oMailer.Send() Console.WriteLine("The message has been successfully sent.") Catch e As MailBeeSmtpRefusedRecipientException Console.WriteLine("The following recipient was refused by SMTP server: " + e.RefusedRecipientEmail) End Try |
示例代码：
摘要：以下示例创建一个包含纯文本和HTML格式主体的邮件，并添加.xls文档附加。然后将邮件发送给两个指定的收件人。 在使用MailBee.NET Objects之前，请确保它已解锁。| C#: using System; using MailBee; using MailBee.SmtpMail;namespace EmailApp { class Class1 { [STAThread] static void Main(string[] args) { Smtp oMailer = new Smtp();oMailer.From.AsString = "John Doe (Company Info)"; oMailer.To.AsString = "Bill Smith , Kathy Ritchie (Company Info)"; oMailer.Subject = "Test e-mail"; oMailer.BodyPlainText = "This is a test e-mail message."; oMailer.BodyHtmlText = @"Test HTML message. This is a test HTML mes-sage. ";oMailer.AddAttachment(@"C:\annual_reoprt.xls"); oMailer.SmtpServers.Add("127.0.0.1", "login", "password"); oMailer.SmtpServers[0].AllowRefusedRecipients = false; try { oMailer.Send(); Console.WriteLine("The message has been successfully sent."); } catch (MailBeeSmtpRefusedRecipientException e) { Console.WriteLine("The following recipient was refused by SMTP server: "+ e.RefusedRecipientEmail); } } } }
