D365FO. Working with Azure File storage.

Azure Storage - Files

Current version of AX uses Azure Blob storage for various things like document handling, retail CDX files, DIXF and Excel add-in. You can find several blogs explaining how to upload and download files to Blob, SharePoint or temporary storage. However, what about file shares?

Azure File storage implements SMB 3.0 protocol and could be easily mapped to your local computer. You need just a few minutes to create new storage account and mount it, watch this how-to video for details.

To read file from newly created share we can use next code:

using Microsoft.Azure;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
using Microsoft.WindowsAzure.Storage.File;

class RunnableClass1
{
    public static void main(Args _args)
    {
        System.IO.MemoryStream memoryStream;

        var storageCredentials = new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials('AzureStorageAccountName', 'AzureStorageAccountKey');

        CloudStorageAccount storageAccount = new Microsoft.WindowsAzure.Storage.CloudStorageAccount(storageCredentials, true);

        CloudFileClient fileClient = storageAccount.CreateCloudFileClient();

        CloudFileShare share = fileClient.GetShareReference('AzureStorageShareName');

        if (share.Exists(null, null))
        {
            CloudFileDirectory rootDir = share.GetRootDirectoryReference();

            CloudFileDirectory fileDir = rootDir.GetDirectoryReference('folder');

            if (fileDir.Exists(null, null))
            {
                CloudFile file = fileDir.GetFileReference('file.txt');

                if (file.Exists(null, null))
                {
                    memoryStream = new System.IO.MemoryStream();
                    file.DownloadToStream(memoryStream, null, null, null);
                }
            }
        }
    }
}
