AzMultiProtocolAccess is a sample application designed to showcase how to use Multi-protocol access on Azure Data Lake Storage Gen2. The following actions will be performed in sequence:

• Generating Fake Data
• Uploading files using Azure DFS API
• Listing files using Azure Blob API using a PageSize
• Downloading files using Azure Blob API
• Uploading files using Azure Blob API and keeping folder structure
• Listing files using Azure DFS API
• Downloading files and creating folder structure locally using Azure DFS API

To use this sample, you need to have an Azure subscription. If you do not have an Azure subscription, you can create a free account before you begin. For more information, see Create an Azure free account.

All access to Azure Storage takes place through a storage account. For this sample, create a storage account using the Azure portal, Azure PowerShell, or Azure CLI. For help creating a storage account, see Create a storage account and enable hierarchical namespace for Multi-protocol access.

For authentication, Azure Active Directory is used. In this sample read and write operations are performed on a storage account. To grant access to the storage account, you need to grant your Identity at least "Storage Blob Data Contributor" privileges. For more information, see Authorize access to Azure blobs and queues using Azure Active Directory.

# Create Ressource Group 
az group create -n rgAzMultiProtocolAccess -l westeurope

# Create Storage Account with Hierarchical Namespace enabled
az storage account create --name YourAccountName \
--resource-group rgAzMultiProtocolAccess --location westeurope \
--sku Standard_LRS --enable-hierarchical-namespace

# Add Role Assignment and grant your Identity "Storage Blob Data Contributor" privileges
az role assignment create --assignee "[email protected]" \
--role "Storage Blob Data Contributor" \
--scope "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rgAzMultiProtocolAccess/providers/Microsoft.Storage/storageAccounts/YourAccountName"

Before running the sample, you must change "YourAccountName" in the src/Program.cs file (line 11) to the name of your storage account created in the step before.

private static readonly string storageAccountName = "YourAccountName";

Assign the storage account name as a command line argument when running the sample.

dotnet run YourAccountName

To build and run the sample, change to the src directory and execute the following command:

dotnet run
