Hello! I am trying to upload local file to Azure blob storage via X++ code. I am receiving following error for UploadFromFile and UploadFromFileAsync methods among many others I tried. Please see the error message along with code snippet below.

Method 'UploadFromFile(System.Object)' is not found on type 'Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob'.


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

Microsoft.WindowsAzure.Storage.Auth.StorageCredentials storageCredentials = new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials(accountName, accountKey);

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

var blobcli = storageAccount.CreateCloudBlobClient();

Microsoft.WindowsAzure.Storage.Blob.CloudBlobContainer cont = blobcli.GetContainerReference("from-d365");

CloudBlockBlob cloudBlockBlob = cont.GetBlockBlobReference(fileName);
cloudBlockBlob.UploadFromFile(targetFile);

Hi Janis Plavins,

Try to pass FileMode as second parameter (i.e. FileMode.Open). I know that example says that you can use only one parameter but it obviously does not work :)

Hi Janis,

I think the problem is that you are using uploadFromFile with only one parameter and it needs more parameters.

I see the next parameters in my visual studio (2 mandatory parameters):

If you read the MSFT doc, your code is right, but it could be a different version.

https://docs.microsoft.com/en-us/dotnet/api/microsoft.windowsazure.storage.blob.cloudblockblob.uploadfromfile?view=azure-dotnet#Microsoft_WindowsAzure_Storage_Blob_CloudBlockBlob_UploadFromFile_System_String_Microsoft_WindowsAzure_Storage_AccessCondition_Microsoft_WindowsAzure_Storage_Blob_BlobRequestOptions_Microsoft_WindowsAzure_Storage_OperationContext_

Hope it helps you.

Kind regards.

FileMode.Open is c# syntax, in AX you need to write FileMode::Open

I am currently working on upload a file to azure storage. What is the best practice of saving this account name and account key?

Where should i store these pair so it's secure at the same time I can set this for each environment?

I would say "azure key vault", you can find in AOT classes that already work with it, so you can build your own base on them.
