如何將字節數組轉換爲zip文件在c＃中？

Question

我有一個數據庫中的ziparchive字節數組。當我從數據庫檢索數據並嘗試將其轉換回Ziparchive時，它會引發錯誤。有什麼辦法從字節數組轉換爲zipArchive？

Answer 1

從這個answer我認爲這是可能你的流字節數組轉換爲zip壓縮包：

using (var compressedFileStream = new MemoryStream()) { 
    //Create an archive and store the stream in memory. 
    using (var zipArchive = new ZipArchive(compressedFileStream, ZipArchiveMode.Update, false)) { 
     foreach (var caseAttachmentModel in caseAttachmentModels) { 
      //Create a zip entry for each attachment 
      var zipEntry = zipArchive.CreateEntry(caseAttachmentModel.Name); 

      //Get the stream of the attachment 
      using (var originalFileStream = new MemoryStream(caseAttachmentModel.Body)) { 
       using (var zipEntryStream = zipEntry.Open()) { 
        //Copy the attachment stream to the zip entry stream 
        originalFileStream.CopyTo(zipEntryStream); 
       } 
      } 
     } 

    } 

    return new FileContentResult(compressedFileStream.ToArray(), "application/zip") { FileDownloadName = "Filename.zip" }; 
} 

這裏，用線new FileContentResult(compressedFileStream.ToArray(), "application/zip") { FileDownloadName = "Filename.zip" };，如果你已經轉換成zip文件，那麼你可以將您的流字節數組到這樣的zip存檔：

new FileContentResult(your_stream_byte_array, "application/zip") { FileDownloadName = "Filename.zip" };
