In this sample, you will find the following folders:

• v11 - references Storage Blob SDK v11
• v12 - references Storage Blob SDK v12

To complete this tutorial:

• Install .NET Core latest version for Linux or Windows

If you don't have an Azure subscription, create a free account before you begin.

Step 1 : Create a new general-purpose Storage Account to use for this tutorial.

• Go to the Azure Portal and log in using your Azure account.
• Select New > Storage > Storage account.
• Select your Subscription.
• For Resource group, create a new one and give it a unique name.
• Enter a name for your storage Account.
• Select the Location to use for your Storage Account.
• Set Account kind to StorageV2(general purpose v2).
• Set Performance to Standard.
• Set Replication to Locally-redundant storage (LRS).
• Set Secure transfer required to Disabled.
• Check Review + create and click Create to create your Storage Account.

Step 2 : Copy and save Connection string.

After your Storage Account is created. Click on it to open it. Select Settings > Access keys > Key1/key, copy the associated Connection string to the clipboard, then paste it into a text editor for later use.

This solution requires a connection string be stored in an environment variable securely on the machine running the sample. Follow one of the examples below depending on your operating system to create the environment variable. If using Windows close your open IDE or shell and restart it to be able to read the environment variable.

Linux

export AZURE_STORAGE_CONNECTIONSTRING="<YourConnectionString>"

Windows

setx AZURE_STORAGE_CONNECTIONSTRING "<YourConnectionString>"

At this point, you can run this application. It creates its own file to upload and download, and then cleans up after itself by deleting everything at the end.

First, clone the repository on your machine:

git clone https://github.com/Azure-Samples/azure-sdk-for-net-storage-blob-upload-download.git

Then, switch to the appropriate folder:

cd v11

or

cd v12

Finally, run the application with the dotnet run command.

dotnet run

• Create a Storage Account using the Azure Portal.
• Create a container.
• Upload a file to block blob.
• List blobs.
• Download a blob to file.
• Delete a blob.
• Delete the container.

The Azure Storage documentation includes a rich set of tutorials and conceptual articles, which serve as a good complement to the samples.
