我正在尝试创建一个将流式传输给用户的DotNetZip zip文件.在zip文件中,我插入了两个内存流.但由于某种原因,当我打开zip文件时,它是空的.我查看了文档,发现几乎没有任何帮助.我的代码:

        p1.AppendLine("Text information...");
        Paragraph p2 = doc.InsertParagraph();
        p2.AppendLine("DISCLAIMER: ...");
        doc.SaveAs(msDoc);

//Create Zip File and stream it to the user
        MemoryStream msZip = new MemoryStream();
        ZipFile zip = new ZipFile();
        msImage.Seek(0, SeekOrigin.Begin);
        msDoc.Seek(0, SeekOrigin.Begin);
        ZipEntry imageEntry = zip.AddEntry("MyImageName.jpg", msImage);
        ZipEntry …
