SharpZipLib的基础知识.我错过了什么？

Question

我的代码中有以下方法:

private bool GenerateZipFile(List<FileInfo> filesToArchive, DateTime archiveDate)
{
    try
    {
        using (ZipOutputStream zipStream = new ZipOutputStream(File.Create(GetZipFileName(archiveDate))))
        {
            zipStream.SetLevel(9); // maximum compression.
            byte[] buffer = new byte[4096];

            foreach (FileInfo fi in filesToArchive)
            {
                string fileName = ZipEntry.CleanName(fi.Name);
                ZipEntry entry = new ZipEntry(fileName);
                entry.DateTime = fi.LastWriteTime;
                zipStream.PutNextEntry(entry);

                using (FileStream fs = File.OpenRead(fi.FullName))
                {
                    StreamUtils.Copy(fs, zipStream, buffer);
                }

                zipStream.CloseEntry();
            }

            zipStream.Finish();
            zipStream.Close();
        }
        return true; 
    }
    catch (Exception ex)
    {
        OutputMessage(ex.ToString());
        return false;
    }
}

此代码生成包含所有正确条目的ZIP文件,但每个文件都列为4 TB(解压缩和打包),并在尝试打开时创建以下错误:

Extracting to "C:\winnt\profiles\jbladt\LOCALS~1\Temp\"
Use Path: no   Overlay Files: yes
skipping: QPS_Inbound-20081113.txt: this file is not in the standard Zip 2.0 format
   Please see www.winzip.com/zip20.htm for more information
error:  no files were found - nothing to do

代码实际上取自样本,但我似乎缺少一些东西.有没有人有任何指针？

我曾经使用SharpZipLib,直到我切换到DotNetZip您可能想要检查它作为替代.

例:

try
   {
     using (ZipFile zip = new ZipFile("MyZipFile.zip")
     {
       zip.AddFile("c:\\photos\\personal\\7440-N49th.png");
       zip.AddFile("c:\\Desktop\\2005_Annual_Report.pdf");
       zip.AddFile("ReadMe.txt");
       zip.Save();
     }
   }
   catch (System.Exception ex1)
   {
     System.Console.Error.WriteLine("exception: " + ex1);
   }
