Send email using fluent interface

// C# version

using Fluent = Limilabs.Mail.Fluent;

Fluent.Mail.Html(@"Html with an image: <img src=""cid:lena"" />")
  .AddVisual(@"c:lena.jpeg").SetContentId("lena")
  .AddAttachment(@"c:tmp.doc").SetFileName("document.doc")
  .To("to@mail.com")
  .From("from@mail.com")
  .Subject("Subject")
  .UsingNewSmtp()
  .Server("smtp.example.org")
  .WithSSL()
  .WithCredentials("user", "password")
  .Send();

' VB.NET version

Imports Fluent = Limilabs.Mail.Fluent;

Fluent.Mail.Html("Html with an image: <img src=""cid:lena"" />") _
  .AddVisual("c:lena.jpeg").SetContentId("lena") _
  .AddAttachment("c:tmp.doc").SetFileName("document.doc") _
  .[To]("to@mail.com") _
  .From("from@mail.com") _
  .Subject("Subject") _
  .UsingNewSmtp() _
  .Server("smtp.example.org") _
  .WithSSL() _
  .WithCredentials("user", "password") _
  .Send()

Fluent interface for creating and sending emails was added to Mail.dll as an additional feature.

You can still use MailBuilder class to create emails.
Note that error handling code was removed for simplicity, you should use try…catch block when sending.

If your server does not require authentication or SSL simply skip WithSSL and WithCredentials methods:

// C# version

Mail.Text("Hi there")
    .Subject("Hi")
    .To("to@mail.com")
    .From("from@example.org")
    .UsingNewSmtp()
    .Server("smtp.example.org")
    .Send();

' VB.NET version

Mail.Text("Hi there") _
  .Subject("Hi") _
  .[To]("to@mail.com") _
  .From("from@example.org") _
  .UsingNewSmtp() _
  .Server("smtp.example.org") _
  .Send()

Same code using MailBuilder:

// C# version

MailBuilder builder = new MailBuilder();
builder.Text = "Hi there";
builder.Subject = "Hi";
builder.To.Add(new MailBox("to@mail.com"));
builder.From.Add(new MailBox("from@example.org"));
IMail email= builder.Create();

using(Smtp smtp = new Smtp())
{
    smtp.Connect("smtp.example.org"); // or ConnectSSL
    // smtp.UseBestLogin("user", "password");
    smtp.SendMessage(email);
    smtp.Close();
}

' VB.NET version

Dim builder As New MailBuilder()
builder.Text = "Hi there"
builder.Subject = "Hi"
builder.[To].Add(New MailBox("to@mail.com"))
builder.From.Add(New MailBox("from@example.org"))

Dim emailAs IMail = builder.Create()

Using smtp As New Smtp()
    smtp.Connect("smtp.example.org") ' or ConnectSSL
    ' smtp.UseBestLogin("user", "password")
    smtp.SendMessage(email)
    smtp.Close()
End Using

You can also reuse existing Smtp connection to send multiple emails using fluent interface:

// C# version

using(Smtp smtp = new Smtp())
{
    smtp.Connect("smtp.example.org"); // or ConnectSSL
    smtp.UseBestLogin("user", "password");

    Mail.Text("Hi there")
        .Subject("Hi")
        .To("to@mail.com")
        .From("from@example.org")
        .Send(smtp);

    // Send more emails here...

    smtp.Close();
}

' VB.NET version

Using smtp As New Smtp()
	smtp.Connect("smtp.example.org") ' or ConnectSSL
	smtp.UseBestLogin("user", "password")

	Mail.Text("Hi there") _
          .Subject("Hi") _
          .[To]("to@mail.com") _
          .From("from@example.org") _
          .Send(smtp)

	' Send more emails here...

	smtp.Close()
End Using
