下面是使用visual basic 10发送电子邮件的示例。首先，您需要构建一个包含字段to，from，text和email_send按钮的表单，现在下面的代码

Private Smtp_Server As New SmtpClient()

Private Sub email_send_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles email_send.Click
Try

Dim e_mail As New MailMessage()
Smtp_Server.Credentials = New Net.NetworkCredential("[email protected]", "password")
Smtp_Server.Port = 25
Smtp_Server.Host = "mail.v-basic.net"
e_mail = New MailMessage()
e_mail.From = New MailAddress(from_txt.Text)
e_mail.To.Add(to_txt.Text)
e_mail.Subject = "VB.NET Email Sending"
e_mail.Body = text_txt.Text
Smtp_Server.Send(e_mail)

Catch error_t As Exception
MsgBox(error_t.ToString)
End Try
End Sub

您可以创建一个名为“Mail”的新类。如果您要创建课程，则如果要发送超过1封电子邮件，则无需再次键入所有代码。

Imports System.Net.Mail
Public NotInheritable Class Mail
    Public Property subject As String
    Public Property body As String
    Public Property receiver As String

    Public Sub send()
        Try
            Dim smtpServer As New SmtpClient()
            Dim mail As New MailMessage()
            smtpServer.UseDefaultCredentials = False
            smtpServer.Credentials = New Net.NetworkCredential("[email protected]", "password"))
            smtpServer.Port = 587
            smtpServer.EnableSsl = True
            smtpServer.Host = "smtp.gmail.com"

            mail = New MailMessage()
            mail.From = New MailAddress("[email protected]")
            mail.To.Add(receiver)
            mail.Subject = subject
            mail.Body = body
            smtpServer.Send(mail)
        Catch ex As Exception
            MsgBox(ex.Message & vbNewLine & ex.StackTrace)
        End Try

    End Sub
End Class

然后，您可以在代码中创建一个新对象，以便在何时何地发送电子邮件：

Dim email as new Mail
email.receiver = "[email protected]"
email.subject = "Subject"
email.body = "Message"
email.send()

Imports System.Net.Mail
Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click


        Try
            Dim Smtp_Server As New SmtpClient
            Dim e_mail As New MailMessage()
            Smtp_Server.UseDefaultCredentials = False
            Smtp_Server.Credentials = New Net.NetworkCredential("[email protected]", "Password")
            Smtp_Server.Port = 587
            Smtp_Server.EnableSsl = True
            Smtp_Server.Host = "smtp.gmail.com"

            e_mail = New MailMessage()
            e_mail.From = New MailAddress(TextBox1.Text)
            e_mail.To.Add(TextBox2.Text)
            e_mail.Subject = "Email Sending"
            e_mail.IsBodyHtml = False
            e_mail.Body = txtmsg.Text
            Smtp_Server.Send(e_mail)
            MsgBox("Mail Sent")

        Catch error_t As Exception
            MsgBox(error_t.ToString)
        End Try

    End Sub

End Class
