dotnet add package Aspose.Email.Foss

using System.IO;
using Aspose.Email.Foss.Msg;

using var stream = File.OpenRead("sample.msg");
var message = MapiMessage.FromStream(stream);

Console.WriteLine($"Subject: {message.Subject}");
Console.WriteLine($"From: {message.SenderEmailAddress}");
Console.WriteLine($"Body: {message.Body}");

foreach (var recipient in message.Recipients)
    Console.WriteLine($"To: {recipient.EmailAddress}");

foreach (var attachment in message.Attachments)
    Console.WriteLine($"Attachment: {attachment.Filename} ({attachment.MimeType})");

using System.IO;
using Aspose.Email.Foss.Msg;

var message = MapiMessage.Create("Meeting Notes", "Please find the notes attached.");
message.SenderName = "Alice";
message.SenderEmailAddress = "alice@example.com";
message.AddRecipient("bob@example.com", "Bob");

// Add a file attachment
message.AddAttachment("notes.txt", System.Text.Encoding.UTF8.GetBytes("Meeting notes here"), "text/plain");

// Save to file
message.Save("meeting_notes.msg");
Console.WriteLine("Created meeting_notes.msg");

using System.IO;
using Aspose.Email.Foss.Msg;

// Load from EML
using var input = File.OpenRead("message.eml");
var message = MapiMessage.LoadFromEml(input);

Console.WriteLine($"Subject: {message.Subject}");

// Save as MSG
message.Save("converted.msg");
Console.WriteLine("Saved converted.msg");

// Or save back to EML (round-trip)
message.SaveToEml("roundtrip.eml");
