I've created this for a console application, but that's not necessary.
First we need to import this:
Now we start by making a Sub, all code will be located in the same sub.
Private Sub SendEmail(ByVal MailFrom As String, ByVal MailPass As String, _ ByVal MailTo As String, ByVal MailSubj As String, _ ByVal MailText As String, ByVal MailFromName As String, _ ByVal MailToName As String, _ Optional ByVal MailAttach As String = "")
Here we got:
MailFrom Your mail address
MailPass Your password
MailTo the person who you want to send the mail to's email address
MailSubj The subject of the email
MailText the text in the email
MailFromName the name which is showed as the sender
MailToName the name which is showed as the target
MailAttach files to attach with the email, sepperated with commas
Now we need to test all the variables, first:
If MailSubj = "" Then MailSubj = "No Subject" End If
If there was an empty string as Subject we replaced it with "No Subject".
Then we need to test the email addresses:
If MailTo = "" Then Console.WriteLine("Error.....You must enter a Email Adress as target...") Exit Sub End If Dim MailServer As String = "" If MailFrom = "" Then Console.WriteLine("Error.....You must enter a Email Adress as sender...") Exit Sub ElseIf MailFrom.ToLower.EndsWith("@gmail.com") Then MailServer = "smtp.gmail.com" ElseIf MailFrom.ToLower.EndsWith("@hotmail.com") Then MailServer = "smtp.live.com" Else Console.WriteLine("Error.....Unsupported host...") Exit Sub End If
First we tested if the Target's Email wasn't an empty string, the we tested the Sender's email and searched for the right MailServer (I only know gmails and hotmails. You can send to everyone though).
Then we check if the password exists:
If MailPass = "" Then WriteLine("Error.....You must enter your password...") Exit Sub End If
Now we're creating two variables as mail addresses, we got Try,catch blocks if the email addresses shouldn't be valid:
Dim mTo As System.Net.Mail.MailAddress Try Dim AdressTo As New System.Net.Mail.MailAddress(MailTo, MailToName) mTo = AdressTo Catch Console.WriteLine("Error.....Invailed Target Adress") Exit Sub End Try Dim mFrom As System.Net.Mail.MailAddress Try Dim AdressFrom As New System.Net.Mail.MailAddress(MailFrom, MailFromName) mFrom = AdressFrom Catch Console.WriteLine("Error.....Invailed Sender Adress") Exit Sub End Try
Now with a simple code we create the message and adds the subject and the text:
Dim NEWMail As New MailMessage(mFrom, mTo) NEWMail.Body = MailText NEWMail.Subject = MailSubj
Now we are going to add attachments, if their are any:
If MailAttach <> "" Then Dim Attach As String = "" For Chars As Integer = 0 To MailAttach.Length - 1 If MailAttach(Chars) = "," Or (Chars = MailAttach.Length - 1 And Attach <> "") Then Try NEWMail.Attachments.Add(New Attachment(Attach)) Attach = "" Catch Console.WriteLine("Couldn't add the attachment") Exit Sub End Try Else Attach &= MailAttach(Chars) End If Next End If
We just split the string to different attachment and then tried to add them as an attachment to the email.
We need to create a SmtpClient, It's it which sends the mail:
Dim client As New SmtpClient(MailServer, 587) client.EnableSsl = True client.Credentials = New Net.NetworkCredential(MailFrom, MailPass)
Now we only need to add the actual sending:
Console.WriteLine("Sending email...") Try client.Send(NEWMail) Catch Console.WriteLine("Error.....Failed to send the Email...") Exit Sub End Try Console.WriteLine("Email was sent sucessfully...")
That's it!! I will show an example how to use this:
Sub Main() SendEmail("MyMail@hotmail.com", "Password", "YourMail@hotmail.com", "Test Subject", "This is a text", "Me", "You", "C:\Test.txt,C:\Test2.txt") End Sub
