Azure 文件存储：创建嵌套目录

Question

我的代码是这样的

CloudFileClient client = ...;

client.GetShareReference("fileStorageShare")
    .GetRootDirectoryReference()
    .GetDirectoryReference("one/two/three")
    .Create();

如果目录一或两个不存在，则会出现此错误。有没有办法通过一次调用创建这些嵌套目录？

Answer 1

这是不可能的。 SDK不支持这种方式，您需要一个一个创建。

一个问题已经提交 here。

如果您想一一创建它们，可以使用以下示例代码：

static void NestedDirectoriesTest()
{
   var cred = new StorageCredentials(accountName, accountKey);
   var account = new CloudStorageAccount(cred, true);
   var client = account.CreateCloudFileClient();
   var share = client.GetShareReference("temp2");
   share.CreateIfNotExists();
   var cloudFileDirectory = share.GetRootDirectoryReference();

   //Specify the nested folder
   var nestedFolderStructure = "Folder/SubFolder";
   var delimiter = new char[] { '/' }; 
   var nestedFolderArray = nestedFolderStructure.Split(delimiter);
   for (var i=0; i<nestedFolderArray.Length; i++)
   {
       cloudFileDirectory = cloudFileDirectory.GetDirectoryReference(nestedFolderArray[i]);
       cloudFileDirectory.CreateIfNotExists();
       Console.WriteLine(cloudFileDirectory.Name + " created...");
   }
}

根据 Ivan Yang 的建议，我使用 Azure.Storage.Files.Shares（版本=12.2.3.0）调整了我的代码。

这是我的贡献：

readonly string storageConnectionString = "yourConnectionString";
readonly string shareName = "yourShareName";

public string StoreFile(string dirName,string fileName, Stream fileContent)
{
    // Get a reference to a share and then create it
    ShareClient share = new ShareClient(storageConnectionString, shareName);
    share.CreateIfNotExists();

    // Get a reference to a directory and create it
    string[] arrayPath = dirName.Split('/');
    string buildPath = string.Empty;
    var tempoShare = share;
    ShareDirectoryClient directory = null; // share.GetDirectoryClient(dirName);
    // Here's goes the nested directories builder
    for (int i=0; i < arrayPath.Length; i++)
    {
        buildPath += arrayPath[i];
        directory = share.GetDirectoryClient(buildPath);
        directory.CreateIfNotExists();
        buildPath += '/';
    }
     // Get a reference to a file and upload it
    ShareFileClient file = directory.GetFileClient(fileName);
    using (Stream stream = fileContent)
    {
        file.Create(stream.Length);
        file.UploadRange(new HttpRange(0, stream.Length), stream);
    }
    return directory.Path;
}

这是哈根的简化版本：

public async Task<ShareFileClient> CreateFileClient(string connection, string shareName, string path)
{
    var share = new ShareClient(connection, shareName);
    await share.CreateIfNotExistsAsync();

    var dir = share.GetRootDirectoryClient();
    var pathChain = path.Split(Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar);
    int dirCount = pathChain.Length - 1;

    for (int i = 0; i < dirCount; ++i)
    {
        dir = dir.GetSubdirectoryClient(pathChain[i]);
        await dir.CreateIfNotExistsAsync();
    }

    return dir.GetFileClient(pathChain[dirCount]);
}
