c# - 在 C# 中使用 MimeKit 获取字节数组中的附件

Question

使用 MimeKit 时如何获取附件内容？这就是我所拥有的：

var mimeMessage = MimeMessage.Load(@"test.eml");
var attachments = mimeMessage.Attachments.ToList();

foreach (var attachment in attachments)
{
    // how do I get the content here (array of bytes or stream)
}

这应该做你需要的：

var mimeMessage = MimeMessage.Load(@"test.eml");
var attachments = mimeMessage.Attachments.ToList();

foreach (var attachment in attachments)
{
    using (var memory = new MemoryStream ())
    {
        if (attachment is MimePart)
            ((MimePart) attachment).Content.DecodeTo (memory);
        else
            ((MessagePart) attachment).Message.WriteTo (memory);

        var bytes = memory.ToArray ();
    }
}
