It's strongly recommended that you use the latest version of the Storage Blob SDK package, please refer to the following examples:. If you don't have an Azure subscription, create a free account before you begin. This project welcomes contributions and suggestions.

You will only need to do this once across all repos using our CLA. In a console window such as cmd, PowerShell, or Bash , use Maven to create a new console app with the name blob-quickstart-v Type the following mvn command to create a "Hello world! In side the blob-quickstart-v12 directory, create another directory called data.
This is where the blob data files will be created and stored. Open the pom. Add the following dependency element to the group of dependencies.
When the sample application makes a request to Azure Storage, it must be authorized. To authorize a request, add your storage account credentials to the application as a connection string. To view your storage account credentials, follow these steps:. Here, you can view the account access keys and the complete connection string for each key. In the key1 section, locate the Connection string value. Select the Copy to clipboard icon to copy the connection string.
You will add the connection string value to an environment variable in the next section. After you copy the connection string, write it to a new environment variable on the local machine running the application.
This example comments out the upload task and uncomments the download task and the task to delete the content in the storage account when complete. After the application has been updated, you need to build the application again. Rebuild the application by running dotnet build as seen in the following example:. Now that the application has been rebuilt it is time to run the application with the updated code.
The application reads the containers located in the storage account specified in the storageconnectionstring. It iterates through the blobs using the GetBlobs method and downloads them to the local machine using the DownloadToAsync method. It iterates through the blobs 10 at a time using the ListBlobsSegmentedAsync method in the containers and downloads them to the local machine using the DownloadToFileAsync method.
The following table shows the BlobRequestOptions defined for each blob as it is downloaded. While the files are being downloaded, you can verify the number of concurrent connections to your storage account. This command shows the number of connections that are currently opened.
As you can see from the following example, over connections were open when downloading files from the storage account. In part three of the series, you learned about downloading large amounts of data from a storage account, including how to:. Verify throughput and latency metrics in the portal. Skip to main content. Can you provide sample program for reading and writing files within Container.
