c# - DotNetZip 保存到流

Question

我正在使用 DotNetZip 将文件从 MemoryStream 添加到 zip 文件，然后将该 zip 保存为 MemoryStream，以便我可以将其作为附件通过电子邮件发送.下面的代码没有错误，但 MemoryStream 不能正确完成，因为它不可读。当我将 zip 文件保存到我的硬盘时，一切正常，只是当我尝试将它保存到流中时却不是这样。

using (ZipFile zip = new ZipFile())
{
var memStream = new MemoryStream();
var streamWriter = new StreamWriter(memStream);

streamWriter.WriteLine(stringContent);

streamWriter.Flush();      
memStream.Seek(0, SeekOrigin.Begin);

ZipEntry e = zip.AddEntry("test.txt", memStream);
e.Password = "123456!";
e.Encryption = EncryptionAlgorithm.WinZipAes256;

var ms = new MemoryStream();
ms.Seek(0, SeekOrigin.Begin);

zip.Save(ms);

//ms is what I want to use to send as an attachment in an email                                   
}

Answer 1

好吧，我想出了我的问题，实际上很愚蠢。感谢大家的帮助!

ZipEntry e = zip.AddEntry("test.txt", memStream);
e.Password = "123456!";
e.Encryption = EncryptionAlgorithm.WinZipAes256;

//zip.Save("C:\\Test\\Test.zip");

//Stream outStream;

var ms = new MemoryStream();

zip.Save(ms);

    //--Needed to add the following 2 lines to make it work----
ms.Seek(0, SeekOrigin.Begin);
ms.Flush();
