VB.net local machine IP Address

Hi

I am trying to use the following code to send an email using System.Net.Mail
It asks for the local machine IP Address
How do I find this programmatically?

    Public Sub SendEmail(ByVal MsgFrom As String, ByVal MsgTo As String, ByVal MsgSubject As String, ByVal MsgBody As String)

        Try

            '  Pass in the message information to a new MailMessage

            Dim msg As New Net.Mail.MailMessage(MsgFrom, MsgTo, MsgSubject, MsgBody)



            '   Create an SmtpClient to send the e-mail

            Dim mailClient As New SmtpClient("127.0.0.1")  '  = local machine IP Address

            '  Use the Windows credentials of the current User

            mailClient.UseDefaultCredentials = True



            ' Pass the message to the mail server

            mailClient.Send(msg)

            '  Optional user reassurance:

            'MsgBox(String.Format("Message Subject ' {0} ' successfully sent From {1} To {2}", MsgSubject, MsgFrom, MsgTo), "EMail", Windows.Forms.MessageBoxButtons.OK)

            '  Housekeeping

            msg.Dispose()

        Catch ex As FormatException

            MsgBox(ex.Message & " :Format Exception")

        Catch ex As SmtpException

            MsgBox(ex.Message & " :SMTP Exception")

        End Try

>Dim mailClient As New SmtpClient("127.0.0.1")

This needs to be the IP address of your email server. Do you have an SMTP server running on the local machine? If not, do you have access to a server? If yes, use that. If not, use a public server like gmail.

Hi MacroShadow
I get 'GetHostByName' is obsolete for the line
System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()
