Hi,

I think you can send your file using business events and power automate to store them to azure blob store.

After putting data into stream you can use BlobServiceClient to upload to blob, something like this:

private void UploadToBlobStorage(Stream stream, string fileName, string folderName)
{
string connectionString = "your_connection_string"; // Replace with your Azure Blob Storage connection string
string containerName = "your_container_name"; // Replace with your container name

BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);
BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);

// Combine folder name and file name to create the blob name
string blobName = $"{folderName}/{fileName}";

BlobClient blobClient = containerClient.GetBlobClient(blobName);

// Upload the stream to the blob
blobClient.Upload(stream, new BlobHttpHeaders { ContentType = "text/plain" });

Console.WriteLine($"File uploaded to Blob Storage: {blobName}");
}

Is this X++ code, actually in x++ we are not using Console.WriteLine and getting below error.

Please follow this link. Using this you just need to pass stream as a parameter which uploads file to azure blog storage.

VaHiX's code indeed isn't X++; it looks like C#.

Hi,

You could find a lot of code online. But some libraries are deprecated so make sure to replace them with new ones.

For example, instead of using Microsoft.Azure.Storage.Blob then maybe use Azure.Storage.Blobs

Check out Microsoft article and check what is deprecated and what is its replacement

Thanks,

Hi,

You could try sth like this ( you can make the code better). But it was announced that some libraries are deprecated so make sure to replace them with new ones if that's the case
System.Exception ex; try { Microsoft.WindowsAzure.Storage.Auth.StorageCredentials storageCredentials = new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials("StorageAccountName", "StorageKey"); Microsoft.WindowsAzure.Storage.CloudStorageAccount storageAccount = new Microsoft.WindowsAzure.Storage.CloudStorageAccount(storageCredentials, true); var blobcli = storageAccount.CreateCloudBlobClient(); Microsoft.WindowsAzure.Storage.Blob.CloudBlobContainer cont = blobcli.GetContainerReference("Container"); stream.Position = 0; Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob cloudBlockBlob = cont.GetBlockBlobReference("fileName"); cloudBlockBlob.UploadFromStream(stream,null,null,null); } catch(ex) { throw error(strFmt("UploadFailed", ex.Message)); }
