==============

Purpose:

The purpose of this post is to demonstrate how we can read a CSV file from Azure File Share in X++.

Application:

Dynamics 365 Finance and Operations

Prerequisites:

• Azure file storage account must be configured in Azure Portal
• File shares must be configured under this Azure file storage account
• Access permissions must be configured for this Azure file storage account

Disclaimer:

This post is only for sharing knowledge. Do not use this code as is in a Production environment.

Business requirement:

Read a CSV file from Azure file share.

Solution:

Please find the code below to read a CSV file from Azure File Share. The code reads ABN numbers from a CSV file. The file has only a single column of ABN numbers with a single number per line.

Code

using Microsoft.Azure;using Microsoft.WindowsAzure.Storage;using Microsoft.WindowsAzure.Storage.Blob;using Microsoft.WindowsAzure.Storage.File;class MAKCloudStorageFileManager{ #File #define.delimiterField(',') public static void main(Args _args) { #OCCRetryCount System.IO.MemoryStream memoryStream; System.String storageAccountName; System.String keyValue; CloudStorageAccount storageAccount; CloudFileClient fileClient; CloudFileShare fileShare; CloudFileDirectory fileDirectoryRoot; CloudFileDirectory fileDirectory; CloudFile file; TextStreamIo textStreamIo; VendTable vendTable; VATNum vendABN; Counter counter; container rec; storageAccountName = "AzureStorageAccountName"; keyValue = "KeyValueString"; var storageCredentials = new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials(storageAccountName, keyValue); storageAccount = new Microsoft.WindowsAzure.Storage.CloudStorageAccount(storageCredentials, true); fileClient = storageAccount.CreateCloudFileClient(); fileShare = fileClient.GetShareReference('AzureFileShareName'); if (fileShare.Exists(null, null)) { fileDirectoryRoot = fileShare.GetRootDirectoryReference(); fileDirectory = fileDirectoryRoot.GetDirectoryReference("Folder/Subfolder"); if (fileDirectory.Exists(null, null)) { file = fileDirectory.GetFileReference('File.csv'); if (file.Exists(null, null)) { memoryStream = new System.IO.MemoryStream(); file.DownloadToStream(memoryStream, null, null, null); textStreamIo = TextStreamIo::constructForRead(memoryStream); try { if (textStreamIo) { if (textStreamIo.status()) { throw Global::error("@SYS52680"); } textStreamIo.inFieldDelimiter(#delimiterField); textStreamIo.inRecordDelimiter(#delimiterCRLF); counter = 0; while (!textStreamIo.status()) { rec = textStreamIo.read(); if (conLen(rec)) { vendABN = conPeek(rec, 1); info(strFmt("%1", vendABN)); } } } } catch (Exception::Error) { error("An error occured. Please contact your system administrator."); } } } } }}
We can use Microsoft Azure Storage Explorer to browse files stored in Azure File Share or Azure Blob Containers.

You can run the class by using the runnable class URL below.
