Get Started With Azure Blob Storage Using .NET

 Step By Step Process To Upload Document In Azure Blob Storage Using .NET

Hi friend's, today we are going to understand how to upload document in azure blob storage. i read many blogs and articals about this but i couldn't find any useful blog for this or provided proper information about blob. i collect many information about azure blob and want to share with you. i hope it is useful for you.

Now first try to understand about azure blob.

1. What is a blob Storage?
2. Blob Service Concepts
3. Create an Azure Storage Account
4. Create a project in visual studio
5. Install client library & Azure Configuration manager using nuget packages
6. Code Upload a Image into a container

1. What Is a Blob Storage?

Azure blob Storage is a provide service, large amount of unstructured data in binary or text format.That can accessed from any where using HTTP or HTTPS.

Common use of blob storage:

• Using blob, image or documents upload directly to browser 
• Using blob, Uploading video or audio
• Storing data for backup and restore 
• Storing data for analysis by an on-premises or Azure-hosted service

2. Blob Service Concepts

• Storage Account: Storage Account is done through azure access storage account. General-purpose storage account or a Blob storage account which is specialised for storing objects/blobs. please check for more information About Azure Storage Account.
• Container: Container provider grouping of a set of blobs. an account can contains number of containers.NOTE: The container name must be an small lovercase.
• Blob: Hear Microsoft describe different type of blob mention below. 
• Block Blobs: Are Storing text or binary file, such as media files.
• Page Blobs: can more efficient to read/write orations.Azure Virtual Machines use page blobs as OS and data disks.
• Append Blobs: Are similar to block blob type

3. Create an Azure Storage Account

• First Create an Azure portal account.
• To learn more, see Create a storage account.
• Then Create Azure Storage Account by using Storage Resource Provider Client Library for .NET

4. Create Project in Visual Studio

In Visual Studio, Create an Console application or project first.hear i create console application.

1.  Select File > New > Project 
2. Select Installed > Templates > Visual C# > Windows Classic Desktop
3. Select Console App (.NET Framework)
4. Enter a name for your application in the Name: field
5. Select OK

5. Install client library & Azure Configuration manager using nuget packages

Hear two main package need to reference in your project.

• Microsoft Storage Client Library for .Net:
• In Visual Studio, Tool > NuGetPackage Manager > Package manager then use this command in command manager.
• PM> Install-Package WindowsAzure.Storage -Version 8.4.0
• Microsoft Azure Configuration Manager 
• In Visual Studio, Tool > NuGetPackage Manager > Package manager then use this command in command manager.
• PM>Install-Package Microsoft.WindowsAzure.ConfigurationManager -Version 3.2.3

6. Code Upload a Image into a container

• Create one class file in created project like xxx.cs file.
• Created this class file Create Static method.

Below mention .net c# code for upload image using block blob type blob storage

static void Main(string[] args)
{
    UploadImageInToBlobStorage();
}

//Class file method

public static void UploadImageInToBlobStorage()
{
// Block blob basics example
StartBlockBlobOperationsAsync().Wait();
}

private static async Task StartBlockBlobOperationsAsync()
{

CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));

CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();

CloudBlobContainer cloudBlobContainer = cloudBlobClient.GetContainerReference("adftechnobrainsblob");

if (await cloudBlobContainer.CreateIfNotExistsAsync())

{

await cloudBlobContainer.SetPermissionsAsync(

new BlobContainerPermissions

{

PublicAccess = BlobContainerPublicAccessType.Blob

}

);

}

CloudBlockBlob cloudBlockBlob = cloudBlobContainer.GetBlockBlobReference("Image Name Hear");

cloudBlockBlob.Properties.ContentType = filetype;

//HttpPostedFileBase file object property use InputStream

await cloudBlockBlob.UploadFromStreamAsync(Image Stream hear);

}

In Web.config file, under the appSetting key 

So, that's all guys i hope These will you to understand basic of Azure blob upload document.
