将文件夹压缩为多个zip文件 [英] compress a folder into multiple zip files

问题描述

亲爱的所有人，

i我正在寻找一些可以帮助我理解如何在C＃中压缩文件的例子，即如果我有文件夹大小= 20MB，我想压缩它将存档拆分为4个部分，每个5MB。当我有这4个文件时，我可以将它们提取到原始文件中。因此，每个单独的部分可能不是一个合适的拉链，但所有4个部分应该正确提取



有人建议吗？谢谢，

Dear All,
i am looking for some example which can help me to understand how can i zip files in C# in parts i.e. if i have Folder Size = 20MB , I want to Compress It As split the archive in 4 parts of 5MB each. when i have those 4 files, I can extract them to the original files. So each individual part may not be a proper zip but all 4 parts should extract properly

Could someone suggest? thanks,

using (var memoryStream = new MemoryStream())
{
 using (var archive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))
 {
  var demoFile = archive.CreateEntry("foo.txt");

 }

 using (var fileStream = new FileStream(@"C:\Temp\test.zip", FileMode.Create))
   {
     memoryStream.Position=0;
     memoryStream.WriteTo(fileStream);
   }
 }

Iam使用System.IO.Compression和一段时间Foo.txt超过3千兆所以我需要分割这个文件到多个压缩文件



谢谢

Thanks
