Mailkit C# (Wie es für Entwickler funktioniert)

Installing MailKit in Your Project

To start using MailKit in your application, you need to install the MailKit package. This can be done via MailKit on NuGet, a package manager for .NET. Here's how you can do it:

• Open your C# project in Visual Studio
• Navigate to the Solution Explorer, right-click on your project, and select Manage NuGet Packages
• Search for 'MailKit' in the NuGet Package Manager and install it.

Setting Up MailKit for Email Operations

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;

        // Set the email body as plain text
        message.Body = new TextPart("plain")
        {
            Text = body
        };

        using (var client = new SmtpClient())
        {
            // Connect to the SMTP server
            client.Connect("smtp.server.com", 587, false);
            // Authenticate using your email credentials
            client.Authenticate("your@email.com", "yourpassword");
            // Send the email
            client.Send(message);
            // Disconnect from the server
            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;

        // Set the email body as plain text
        message.Body = new TextPart("plain")
        {
            Text = body
        };

        using (var client = new SmtpClient())
        {
            // Connect to the SMTP server
            client.Connect("smtp.server.com", 587, false);
            // Authenticate using your email credentials
            client.Authenticate("your@email.com", "yourpassword");
            // Send the email
            client.Send(message);
            // Disconnect from the server
            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

		' Set the email body as plain text
		message.Body = New TextPart("plain") With {.Text = body}

		Using client = New SmtpClient()
			' Connect to the SMTP server
			client.Connect("smtp.server.com", 587, False)
			' Authenticate using your email credentials
			client.Authenticate("your@email.com", "yourpassword")
			' Send the email
			client.Send(message)
			' Disconnect from the server
			client.Disconnect(True)
		End Using
	End Sub
End Class

Configuring SMTP Server for Sending Emails

using MailKit.Net.Smtp;

// Connecting and authenticating to 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 MailKit.Net.Smtp;

// Connecting and authenticating to 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);
}

Imports MailKit.Net.Smtp

' Connecting and authenticating to Gmail's SMTP server
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

Setting Up IMAP Server for Receiving Emails

using MailKit.Net.Imap;

// Connecting and authenticating to Gmail's IMAP server
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 MailKit.Net.Imap;

// Connecting and authenticating to Gmail's IMAP server
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);
}

Imports MailKit.Net.Imap

' Connecting and authenticating to Gmail's IMAP server
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

Integrating Advanced MailKit Features

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.

using MimeKit;

// Creating a MimeMessage for an HTML email
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";

// Build the HTML body
var builder = new BodyBuilder
{
    HtmlBody = @"<html><body><h1>Hello, World!</h1></body></html>"
};

// Set the message body
message.Body = builder.ToMessageBody();

using MimeKit;

// Creating a MimeMessage for an HTML email
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";

// Build the HTML body
var builder = new BodyBuilder
{
    HtmlBody = @"<html><body><h1>Hello, World!</h1></body></html>"
};

// Set the message body
message.Body = builder.ToMessageBody();

Imports MimeKit

' Creating a MimeMessage for an HTML email
Private 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"

' Build the HTML body
Dim builder = New BodyBuilder With {.HtmlBody = "<html><body><h1>Hello, World!</h1></body></html>"}

' Set the message body
message.Body = builder.ToMessageBody()

Implementing HTML Templates

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.

IronPDF is a lightweight .NET PDF library designed specifically with web developers in mind. It makes reading, writing, and manipulating PDF files a breeze, able to convert all kinds of file types into PDF content, and you can use it in your .NET projects for both desktop and web. The best part - it’s free to try out in a development environment.

You can use MailKit and IronPDF together for industry-leading email-to-PDF conversion. Here's a basic implementation:

using IronPdf;

// Render an HTML string as a PDF
var renderer = new IronPdf.ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<html><body><h1>Hey, Chandler!</h1></body></html>");

// Save the PDF document
pdf.SaveAs("EmailContent.pdf");

using IronPdf;

// Render an HTML string as a PDF
var renderer = new IronPdf.ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<html><body><h1>Hey, Chandler!</h1></body></html>");

// Save the PDF document
pdf.SaveAs("EmailContent.pdf");

Imports IronPdf

' Render an HTML string as a PDF
Private renderer = New IronPdf.ChromePdfRenderer()
Private pdf = renderer.RenderHtmlAsPdf("<html><body><h1>Hey, Chandler!</h1></body></html>")

' Save the PDF document
pdf.SaveAs("EmailContent.pdf")

IronPDF is easy to use, but it’s even easier to install. There are a couple of ways you can do it:

Method 1: NuGet Package Manager Console

In Visual Studio, in Solution Explorer, right-click References, and then click Manage NuGet Packages. Hit browse and search ‘IronPDF, and install the latest version. If you see this, it’s working:

You can also go to Tools -> NuGet Package Manager -> Package Manager Console, and enter the following line in the Package Manager Tab:

Install-Package IronPdf

Finally, you can get IronPDF directly from IronPDF's Page on NuGet. Select the Download Package option from the menu on the right and double-click your download to install it automatically, then reload the Solution to start using it in your project.

Didn’t work? You can find platform-specific help on our Advanced NuGet Installation Instructions.
