In C# development, managing and manipulating different forms of data is essential. Two powerful tools that stand out in this regard are MailKit and IronPDF.
This tutorial is designed to guide beginners through the process of integrating these two technologies into a C# application, enabling robust email handling capabilities along with PDF generation and manipulation.
MailKit, a personal open-source project that has become an essential tool in .NET app development, supports sending and receiving emails through SMTP and IMAP protocols. It enables developers to interact with mail servers easily, send HTML emails, and manage security settings, proving crucial for .NET applications requiring email functionalities.
IronPDF allows for generating, rendering, and manipulating PDF documents within .NET apps. It simplifies converting HTML templates to PDFs and creating intricate documents, making it an ideal tool for managing PDFs with web-based data.
MailKit is a comprehensive email framework greatly appreciated in the .NET community for its robust features. It simplifies tasks like sending and receiving emails in .NET applications, including .NET Core and .NET Framework projects.
To start using MailKit in your application, you need to install the MailKit package. This can be done via NuGet, a package manager for .NET. Here's how you can do it:
Once installed, you can begin setting up MailKit in your application. This involves configuring the SMTP server for sending emails and, optionally, the IMAP server for receiving emails. Here's a basic setup:
using MailKit.Net.Smtp;
using MimeKit;
public class EmailService
{
public void SendEmail(string recipientAddress, string subject, string body)
{
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
message.To.Add(new MailboxAddress("", recipientAddress));
message.Subject = subject;
message.Body = new TextPart("plain")
{
Text = body
};
using (var client = new SmtpClient())
{
client.Connect("smtp.server.com", 587, false);
client.Authenticate("your@email.com", "yourpassword");
client.Send(message);
client.Disconnect(true);
}
}
}
using MailKit.Net.Smtp;
using MimeKit;
public class EmailService
{
public void SendEmail(string recipientAddress, string subject, string body)
{
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
message.To.Add(new MailboxAddress("", recipientAddress));
message.Subject = subject;
message.Body = new TextPart("plain")
{
Text = body
};
using (var client = new SmtpClient())
{
client.Connect("smtp.server.com", 587, false);
client.Authenticate("your@email.com", "yourpassword");
client.Send(message);
client.Disconnect(true);
}
}
}
Imports MailKit.Net.Smtp
Imports MimeKit
Public Class EmailService
Public Sub SendEmail(ByVal recipientAddress As String, ByVal subject As String, ByVal body As String)
Dim message = New MimeMessage()
message.From.Add(New MailboxAddress("Your Name", "your@email.com"))
message.To.Add(New MailboxAddress("", recipientAddress))
message.Subject = subject
message.Body = New TextPart("plain") With {.Text = body}
Using client = New SmtpClient()
client.Connect("smtp.server.com", 587, False)
client.Authenticate("your@email.com", "yourpassword")
client.Send(message)
client.Disconnect(True)
End Using
End Sub
End Class
To send emails using MailKit, you need to configure an SMTP server. The SMTP (Simple Mail Transfer Protocol) server is responsible for sending your emails to the intended recipients.
Here's a guide to setting up an SMTP server in your application:
Here's an example of configuring an SMTP client to send emails using Gmail's SMTP server:
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("smtp.gmail.com", 587, MailKit.Security.SecureSocketOptions.StartTls);
smtpClient.Authenticate("yourgmail@gmail.com", "yourpassword");
// Send your message here
smtpClient.Disconnect(true);
}
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("smtp.gmail.com", 587, MailKit.Security.SecureSocketOptions.StartTls);
smtpClient.Authenticate("yourgmail@gmail.com", "yourpassword");
// Send your message here
smtpClient.Disconnect(true);
}
Using smtpClient As New SmtpClient()
smtpClient.Connect("smtp.gmail.com", 587, MailKit.Security.SecureSocketOptions.StartTls)
smtpClient.Authenticate("yourgmail@gmail.com", "yourpassword")
' Send your message here
smtpClient.Disconnect(True)
End Using
To receive and read emails, configure an IMAP (Internet Message Access Protocol) server. IMAP allows you to access and manage your emails directly on the email server, making it a popular choice for email clients.
To connect to an IMAP server, you'll need the server address, port number, and account credentials. Here’s a basic connection setup:
using (var imapClient = new ImapClient())
{
imapClient.Connect("imap.gmail.com", 993, true);
imapClient.Authenticate("yourgmail@gmail.com", "yourpassword");
// Access and manage your inbox here
imapClient.Disconnect(true);
}
using (var imapClient = new ImapClient())
{
imapClient.Connect("imap.gmail.com", 993, true);
imapClient.Authenticate("yourgmail@gmail.com", "yourpassword");
// Access and manage your inbox here
imapClient.Disconnect(true);
}
Using imapClient As New ImapClient()
imapClient.Connect("imap.gmail.com", 993, True)
imapClient.Authenticate("yourgmail@gmail.com", "yourpassword")
' Access and manage your inbox here
imapClient.Disconnect(True)
End Using
Once you've set up the basic functionalities for sending and receiving emails with MailKit, it's time to explore its advanced capabilities.
These include handling HTML emails, using HTML email templates, attaching files, and implementing client-side sorting and searching within the email inbox.
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
message.To.Add(new MailboxAddress("", "recipient@email.com"));
message.Subject = "Your Subject Here";
var builder = new BodyBuilder
{
HtmlBody = @"<html><body><h1>Hello, World!</h1></body></html>"
};
message.Body = builder.ToMessageBody();
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
message.To.Add(new MailboxAddress("", "recipient@email.com"));
message.Subject = "Your Subject Here";
var builder = new BodyBuilder
{
HtmlBody = @"<html><body><h1>Hello, World!</h1></body></html>"
};
message.Body = builder.ToMessageBody();
Dim message = New MimeMessage()
message.From.Add(New MailboxAddress("Your Name", "your@email.com"))
message.To.Add(New MailboxAddress("", "recipient@email.com"))
message.Subject = "Your Subject Here"
Dim builder = New BodyBuilder With {.HtmlBody = "<html><body><h1>Hello, World!</h1></body></html>"}
message.Body = builder.ToMessageBody()
You can also use HTML templates for email content, allowing for more dynamic and visually appealing emails. These templates can be loaded from external files or embedded resources, providing flexibility in how you manage email content.
