在亚马逊S3中创建zip文件夹

Question

我必须在亚马逊S3中创建一个文件夹。现在必须在zip文件中转换该文件夹。我已经使用DotNetZip Liberary转换为.zip文件。这里是链接为

http://dotnetzip.codeplex.com/wikipage?title=CS-Examples

public void ConvertToZip(string directoryToZip, string zipFileName) 
{ 
    try 
    { 

     using (client = DisposableAmazonClient()) 
     { 
      var sourDir = new S3DirectoryInfo(client, bucket, directoryToZip); 

      var destDir = new S3DirectoryInfo(client, bucket, CCUrlHelper.BackupRootFolderPhysicalPath); 

      using (var zip = new ZipFile()) 
      { 
       zip.AddDirectory(sourDir.FullName); // recurses subdirectories 
       zip.Save(Path.Combine(destDir.FullName, zipFileName)); 
      } 
     } 

     logger.Fatal("Successfully converted to Zip."); 
    } 
    catch (Exception ex) 
    { 
     logger.Error("Error while converting to zip. Error : " + ex.Message); 
    } 
} 

当我运行它显示的错误代码“给出的路径的格式不支持。”

S3DirectoryInfo模拟目录结构，但它不是实际的目录结构，并且DotNetZip不知道如何处理指向S3中的对象的字符串。为了让你做到这一点，你将不得不下载文件，压缩它们，然后上传生成的zip文件。以下是一些示例代码，展示了如何做到这一点。

 
class Program 
{ 
    static void Main(string[] args) 
    { 
     var zipFilename = @"c:\temp\data.zip"; 
     var client = new AmazonS3Client(); 
     S3DirectoryInfo rootDir = new S3DirectoryInfo(client, "norm-ziptest"); 
     using (var zip = new ZipFile()) 
     { 
      zip.Name = zipFilename; 
      addFiles(zip, rootDir, ""); 
     }
 

// Move local zip file to S3 
    var fileInfo = rootDir.GetFile("data.zip"); 
    fileInfo.MoveFromLocal(zipFilename); 
} 

static void addFiles(ZipFile zip, S3DirectoryInfo dirInfo, string archiveDirectory) 
{ 

    foreach (var childDirs in dirInfo.GetDirectories()) 
    { 
     var entry = zip.AddDirectoryByName(childDirs.Name); 
     addFiles(zip, childDirs, archiveDirectory + entry.FileName); 
    } 

    foreach (var file in dirInfo.GetFiles()) 
    { 
     using (var stream = file.OpenRead()) 
     {      
      zip.AddEntry(archiveDirectory + file.Name, stream); 

      // Save after adding the file because to force the 
      // immediate read from the S3 Stream since 
      // we don't want to keep that stream open. 
      zip.Save(); 
     } 
    } 
} 
 

}
