在内存中压缩XML文件并将其上传到azure文件存储

Question

我有一个XDocument作为参数提供，需要压缩并上传到Azure文件存储。这里有一些问题部分地回答了这个问题，但是对于blob存储。签名是不同的，我不能让它适用于我的情况，没有在云中获取压缩文件的校验和错误。

public static bool ZipAndUploadDocumentToAzure(XDocument doc, Configuration config) 
    { 
     if (IsNullOrEmpty(config.StorageAccountName) || 
      IsNullOrEmpty(config.StorageAccountKey) || 
      IsNullOrEmpty(config.StorageAccounyShareReference) || 
      IsNullOrEmpty(config.StorageAccounyDirectoryReference)) 
     { 
      return false; 
     } 

     CloudStorageAccount storageAccount = CloudStorageAccount.Parse($"DefaultEndpointsProtocol=https;AccountName={config.StorageAccountName};AccountKey={config.StorageAccountKey}"); 

     CloudFileClient fileClient = storageAccount.CreateCloudFileClient(); 
     CloudFileShare share = fileClient.GetShareReference(config.StorageAccounyShareReference); 
     CloudFileDirectory root = share.GetRootDirectoryReference(); 
     CloudFileDirectory dir = root.GetDirectoryReference(config.StorageAccounyDirectoryReference); 

     var cloudFile = dir.GetFileReference("myarchive.zip"); 


     using (var stream = new MemoryStream()) 
     { 
      var xws = new XmlWriterSettings 
      { 
       OmitXmlDeclaration = true, 
       Indent = true 
      }; 

      using (XmlWriter xw = XmlWriter.Create(stream, xws)) 
      { 
       doc.WriteTo(xw); 
      } 

      //where to actually use ZipArchive 'using block' without saving 
      //any of the zip or XML or XDocument files locally 
      //and that it doesn't produce checksum error 

      cloudFile.UploadFromStream(stream);//this gives me XML file 
               //saved to file storage 
      return true; 
     } 
    }

你实际上需要创建一个ZipArchive然后在那里写你的Xml文档。请参阅下面的示例代码：

static void ZipAndUploadFile() 
    { 
     var filePath = @"C:\Users\Gaurav.Mantri\Desktop\StateProvince.xml"; 
     XDocument doc = null; 
     using (var fs = new FileStream(filePath, FileMode.Open)) 
     { 
      doc = XDocument.Load(fs); 
     } 
     var cred = new StorageCredentials(accountName, accountKey); 
     var account = new CloudStorageAccount(cred, true); 
     var fc = account.CreateCloudFileClient(); 
     var share = fc.GetShareReference("test"); 
     share.CreateIfNotExists(); 
     var rootDirectory = share.GetRootDirectoryReference(); 
     var file = rootDirectory.GetFileReference("test.zip"); 
     using (var stream = new MemoryStream()) 
     { 
      var xws = new XmlWriterSettings 
      { 
       OmitXmlDeclaration = true, 
       Indent = true 
      }; 

      using (var archive = new ZipArchive(stream, ZipArchiveMode.Create, true)) 
      { 
       var entry = archive.CreateEntry("doc.xml"); 
       using (var entryStream = entry.Open()) 
       { 
        using (XmlWriter xw = XmlWriter.Create(entryStream, xws)) 
        { 
         doc.WriteTo(xw); 
        } 
       } 
      } 
      stream.Position = 0; 
      file.UploadFromStream(stream); 
     } 
    }
