vb.net发邮件源码 vba 邮件发送

要一段VB.NET发邮件的代码

'创建发件连接,根据你的发送邮箱的SMTP设置填充

Dim smtp As New System.Net.Mail.SmtpClient("smtp.163.com", 25)

'发件邮箱身份验证,参数分别为 发件邮箱登录名和密码

smtp.Credentials = New System.Net.NetworkCredential("用户名", "密码")

'创建邮件

Dim mail As New System.Net.Mail.MailMessage()

'邮件主题

mail.Subject = "邮件主题"

'主题编码

mail.SubjectEncoding = System.Text.Encoding.GetEncoding("GB2312")

'邮件正文件编码

mail.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312")

'发件人邮箱

mail.From = New System.Net.Mail.MailAddress("example@163.com")

'邮件优先级

mail.Priority = System.Net.Mail.MailPriority.Normal

'HTML格式的邮件,为false则发送纯文本邮箱

mail.IsBodyHtml = True

'邮件内容

mail.Body = "邮件正文内容"

'添加收件人,如果有多个,可以多次添加

mail.To.Add("收件人地址")

'定义附件,参数为附件文件名,包含路径,推荐使用绝对路径

'如果不需要附件,下面三行可以不要

Dim a As New System.Net.Mail.Attachment("附件文件")

'附件文件名,用于收件人收到附件时显示的名称

a.Name = "附件文件名"

'加入附件,可以多次添加

mail.Attachments.Add(a)

'发送邮件

Try

smtp.Send(mail)

MessageBox.Show("发送成功")

Catch

MessageBox.Show("发送失败")

Finally

mail.Dispose()

End Try

Q1: Quoted-Printable编码的邮件解码，vb.net代码怎么写，谢谢

Dim Lines = System.IO.File.ReadAllLines("D:\zhege\qp.txt")

'邮件源代码应该是分行读取vb.net发邮件源码，替换掉这个数组就行。for代码段符合流vb.net发邮件源码的读取行方法（readline）。

Dim codeBuilder As New System.Text.StringBuilder

For Each code As String In Lines

code = code.Replace("==", "=")

If code.EndsWith("=") Then

code = code.Substring(0, code.Count - 1)

codeBuilder.Append(code)

ElseIf code "" Then

codeBuilder.AppendLine(code)

End If

Next

Dim reg As New System.Text.RegularExpressions.Regex("(=(\d|[A-F]){2}){1,}")

Dim match As System.Text.RegularExpressions.Match = Nothing

While reg.IsMatch(codeBuilder.ToString)

match = reg.Match(codeBuilder.ToString)

Dim Bytes As New List(Of Byte)

For Each cMatch As String In Replace(match.Value, "=", "", 1, 1).Split("="c)

Bytes.Add(CByte("h" cMatch))

Next

codeBuilder = codeBuilder.Replace(match.Value, System.Text.Encoding.Default.GetString(Bytes.ToArray))

End While

MsgBox(codeBuilder.ToString)

vb.net发邮件源码我只测试了一段qp代码，可能有误。如果qp不是Default编码，结果可能是乱码，需要注意

Q2: 如何用VB.Net收发邮件

在Identity2.0里面封装vb.net发邮件源码了IIdentityMessageService接口vb.net发邮件源码，可以用来发送接收邮件。

看看

Imports System.Threading.Tasks

Imports System.Security.Claims

Imports Microsoft.AspNet.Identity

Imports Microsoft.AspNet.Identity.EntityFramework

Imports Microsoft.AspNet.Identity.Owin

Imports Microsoft.Owin

Imports Microsoft.Owin.Security

public function SendAsync(message as IdentityMessage) as task

dim credentialUserName = "邮箱登录名"

dim sentFrom = "vb.net发邮件源码你vb.net发邮件源码的邮箱地址"

dim pwd= "邮箱登录密码";

dim client as new System.Net.Mail.SmtpClient("smtp服务器地址")

client.Port = 25'mtp邮件服务器端口

client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network

client.UseDefaultCredentials = false

dim credentials as new System.Net.NetworkCredential(credentialUserName, pwd)

client.EnableSsl = true

client.Credentials = credentials

dim mail as new System.Net.Mail.MailMessage(sentFrom, message.Destination)

mail.Subject = message.Subject

mail.Body = message.Body

return client.SendMailAsync(mail)

end function
