如何在 C# 中读取 MSG 文件

本指南展示了如何使用 Aspose.Email FOSS for .NET 打开 Outlook .msg 文件并提取其内容。

步骤 1 — 安装软件包 

dotnet add package Aspose.Email.Foss

步骤 2 — 加载 MSG 文件 

using Aspose.Email.Foss.Msg;

using var message = MapiMessage.FromFile("sample.msg");

您也可以从流中加载：

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

第3步 — 读取消息字段 

Console.WriteLine($"Subject: {message.Subject}");
Console.WriteLine($"From: {message.SenderName} <{message.SenderEmailAddress}>");
Console.WriteLine($"Date: {message.MessageDeliveryTime}");
Console.WriteLine($"Body: {message.Body}");

步骤 4 — 读取收件人 

foreach (var recipient in message.Recipients)
{
    Console.WriteLine($"{recipient.DisplayName} <{recipient.EmailAddress}>");
}

步骤 5 — 提取附件 

foreach (var attachment in message.Attachments)
{
    Console.WriteLine($"Saving: {attachment.Filename}");
    File.WriteAllBytes(attachment.Filename!, attachment.Data);
}

对于嵌入的消息附件：

foreach (var attachment in message.Attachments)
{
    if (attachment.IsEmbeddedMessage)
    {
        Console.WriteLine($"Embedded: {attachment.EmbeddedMessage!.Subject}");
    }
}

完整示例 

using Aspose.Email.Foss.Msg;

using var message = MapiMessage.FromFile("sample.msg");

Console.WriteLine($"Subject: {message.Subject}");
Console.WriteLine($"From: {message.SenderName} <{message.SenderEmailAddress}>");

foreach (var r in message.Recipients)
    Console.WriteLine($"  {r.DisplayName} <{r.EmailAddress}>");

foreach (var a in message.Attachments)
{
    if (a.IsEmbeddedMessage)
        Console.WriteLine($"  Embedded: {a.EmbeddedMessage!.Subject}");
    else
        File.WriteAllBytes(a.Filename!, a.Data);
}
