我不熟悉VB.NET,但您应该能够使用MimeKit来解析这些MIME格式的文件。我已经使用它很长一段时间了。
在C#中,你会做这样的事情:
var message = MimeMessage.Load ("email.msg");
foreach (var attachment in message.Attachments) {
using (var stream = File.Create (attachment.FileName))
attachment.ContentObject.DecodeTo (stream);
}
在VB.NET中,它可能是这样的:
Dim message As MimeMessage.Load ("email.msg")
For Each attachment As MimePart In message.Attachments
Dim stream As File.Create (attachment.FileName)
attachment.ContentObject.DecodeTo (stream)
stream.Dispose ()
