MailMessage.To Property

Gets the address collection that contains the recipients of this e-mail message.

Namespace:  System.Net.Mail
Assembly:  System (in System.dll)

Public ReadOnly Property To As MailAddressCollection

Property Value

Type: System.Net.Mail.MailAddressCollection
A writable MailAddressCollection object.

The To property is used to designate the addresses on the To line of an e-mail message. To add a recipient to an e-mail message, create a MailAddress for the recipient's address, and then add that object to the collection returned by this property.

The following code example demonstrates setting the To property.

Public Shared Sub CreateTestMessage4(ByVal server As String)
    Dim [from] As New MailAddress("")
    Dim [to] As New MailAddress("")
    Dim message As New MailMessage([from], [to])
    message.Subject = "Using the SmtpClient class."
    message.Body = "Using this feature, you can send an e-mail message from an application very easily."
    Dim client As New SmtpClient(server)
    Console.WriteLine("Sending an e-mail message to {0} by using SMTP host {1} port {2}.", [to].ToString(), client.Host, client.Port)

    Catch ex As Exception
        Console.WriteLine("Exception caught in CreateTestMessage4(): {0}", ex.ToString())
    End Try
End Sub
