從蔚藍的文件存儲使用C＃

Question

遞歸獲取文件，我想編寫一個程序來從蔚藍的文件存儲的文件，但問題是沒有定義的目錄深度和文件的isFile屬性始終返回false。目錄

深度沒有定義和文件的ISFILE屬性始終返回false。

如果您想在fileTemp爲File時執行一些操作，請使用以下代碼嘗試。我們可以使用GetType方法來獲取它的類型，然後使用name屬性來獲取它的類型值。如果該值爲「CloudFile」，那麼我們會執行一些操作，例如下載等。

foreach (var fileTemp in fileList) 
{ 
    // Here fileTemp could be file 
    // or directory containing more child directories 
    switch (fileTemp.GetType().Name) 
    { 
     case "CloudFile": 
      var file1 = patientData.GetFileReference(Path.GetFileName(fileTemp.Uri.LocalPath)); 
      file1.FetchAttributes(); 
      byte[] arrTarget = new byte[file1.Properties.Length]; 
      file1.DownloadToByteArray(arrTarget, 0); 
      break; 
     case "CloudFileDirectory": 
      break; 
    } 

}

public static void list_file() 
    { 
     //***** Get list of all files/directories on the file share*****// 
     CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("xxxxxxxxxxxxxxxxxxxxxx_AzureStorageConnectionString")); 
     CloudFileClient fileClient = cloudStorageAccount.CreateCloudFileClient(); 
     CloudFileShare fileShare = fileClient.GetShareReference("dummyfile"); 

     // List all files/directories under the root directory. 
     Console.WriteLine("Getting list of all files/directories under the root directory of the share."); 

     IEnumerable<IListFileItem> fileList = fileShare.GetRootDirectoryReference().ListFilesAndDirectories(); 

     // Print all files/directories listed above. 
     foreach (IListFileItem listItem in fileList) 
     { 
      // listItem type will be CloudFile or CloudFileDirectory. 
      Console.WriteLine(listItem.Uri.Segments.Last()); 
      Console.WriteLine(listItem.GetType()); 
      if(listItem.GetType()== typeof(Microsoft.WindowsAzure.Storage.File.CloudFileDirectory)) 
      { 

       list_subdir(listItem); 
      } 
     } 
    } 
    public static void list_subdir(IListFileItem list) 
    { 
     Console.WriteLine("subdir"); 
     CloudFileDirectory fileDirectory=(CloudFileDirectory)list; 
     IEnumerable<IListFileItem> fileList = fileDirectory.ListFilesAndDirectories(); 


     // Print all files/directories in the folder. 
     foreach (IListFileItem listItem in fileList) 
     { 
      // listItem type will be CloudFile or CloudFileDirectory. 
      Console.WriteLine(listItem.Uri.Segments.Last()); 
     } 
    }
