c# - 无法使用 ShareDirectoryClient 在 azure 中移动目录

Question

通常我们可以使用移动目录

    // source is: "C:\Songs\Elvis my Man"
    // newLocation is: "C:\Songs\Elvis"
    
    try
    {
        // Previous command was: Directory.Move(source, newLocation);
        DirectoryInfo dir = new DirectoryInfo(source);
        dir.MoveTo(newLocation);
    }

catch (Exception e)
{
    Console.WriteLine("Error: "+ e.Message);
}

现在，当使用 azure 时:

        string myconnectionString = ConfigurationManager.ConnectionStrings["StorageConnection"].ConnectionString.ToString();
        string myshareName = "Mysampleshare";
        string mydirName = "Mysampledir";            
        // Get a reference to a share and then create it
        ShareClient myshare = new ShareClient(myconnectionString, myshareName);           
        ShareDirectoryClient directory1 = myshare.GetDirectoryClient(mydirName);

       
        string myshareName2 = "Mysampleshare2";
        string mydirName2 = "Mysampledir2";            
        // Get a reference to a share and then create it
        ShareClient myshare2 = new ShareClient(myconnectionString, myshareName2);           
        ShareDirectoryClient directory2 = myshare2.GetDirectoryClient(mydirName2);
        Directory.Move(directory1.Path, directory2.Path);

我无法使用 azure 将目录从一个位置移动到另一个位置。我遇到了异常。

DirectoryNotFoundException: The path specified by sourceDirName is invalid 

请提出您的建议。

Answer 1

ShareDirectoryClient 本质上实现了 Azure 文件服务 REST API，因此您无法使用 System.IO 操作(例如 Directory.Move)。

有两种可能的解决方案:

1. 如果您想使用SDK，您需要做的就是在源目录中递归列出文件和目录，然后将单个文件从源目录复制到目标目录。您还需要在目标目录中创建目录。复制操作完成后，您将需要从源目录中删除所有文件和目录。只有当源目录为空时，您才可以删除源目录。

您需要执行所有这些操作，因为 REST API 本身并不支持移动操作。要完成移动，您需要执行复制操作，然后执行删除操作。

如果您想使用System.IO，则需要将文件共享安装为共享网络驱动器，以便获得分配给该文件共享的驱动器号。完成后，您将能够使用 System.IO 命名空间中提供的 Directory.Move 等操作。

请尝试以下代码:

using System;
using System.Threading.Tasks;
using Azure.Storage.Files.Shares;

        const string MyconnectionString = "DefaultEndpointsProtocol=https;AccountName=account-name;AccountKey=account-key";

        const string SourceDirectoryName = "source-directory-name";
        private const string RenamedDirectoryName = "new-directory-name";
        
        static async Task Main(string[] args)
        {
            ShareClient myshare = new ShareClient(MyconnectionString, MyshareName);
            ShareDirectoryClient sourceDirectoryClient = myshare.GetDirectoryClient(SourceDirectoryName);
            ShareDirectoryClient targetDirectoryClient = myshare.GetDirectoryClient(RenamedDirectoryName);
            await RenameDirectory(sourceDirectoryClient, targetDirectoryClient);
            Console.WriteLine("Directory renamed.");
        }

        static async Task RenameDirectory(ShareDirectoryClient sourceDirectoryClient,
            ShareDirectoryClient targetDirectoryClient)
        {
            //Create target directory
            await targetDirectoryClient.CreateIfNotExistsAsync();
            //List files and folders from the source directory
            var result = sourceDirectoryClient.GetFilesAndDirectoriesAsync();
            await foreach (var items in result.AsPages())

                    if (item.IsDirectory)
                    {
                        //If item is directory, then get the child items in that directory recursively.
                        await RenameDirectory(sourceDirectoryClient.GetSubdirectoryClient(item.Name),
                            targetDirectoryClient.GetSubdirectoryClient(item.Name));
                    }
                    else
                    {
                        //If item is file, then copy the file and then delete it.
                        var sourceFileClient = sourceDirectoryClient.GetFileClient(item.Name);
                        var targetFileClient = targetDirectoryClient.GetFileClient(item.Name);
                        await targetFileClient.StartCopyAsync(sourceFileClient.Uri);
                        await sourceFileClient.DeleteIfExistsAsync();
                    }
                }
            }
            //Delete source directory.
            await sourceDirectoryClient.DeleteIfExistsAsync();
        }
        
    }
