Uploading Images to Azure Blob Storage using C# SDK

Azure Blob Storage is a cloud-based storage solution for unstructured data such as text and binary data, including images, videos, and audio files. With Azure Blob Storage, you can store and manage large amounts of data, and make it accessible to clients via HTTP or HTTPS.

In this tutorial, we will demonstrate how to upload images to Azure Blob Storage using the Azure Blob Storage C# SDK.

Prerequisites

Before we start, you will need the following:

  • An Azure subscription
  • Visual Studio or any other C# IDE installed on your machine
  • Azure Blob Storage account and connection string
  • An image to upload

Create a new C# Console Application

Open Visual Studio and create a new Console Application project.

Install the Azure Blob Storage SDK

We need to install the Azure Blob Storage SDK to access Azure Blob Storage. To install the SDK, open the NuGet Package Manager Console and run the following command:

Install-Package Azure.Storage.Blobs

Write the code to upload the image

Let’s start by writing the code to upload the image to Azure Blob Storage.

using Azure.Storage.Blobs;
using System;
using System.IO;

namespace AzureBlobStorageDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            string connectionString = "<Your Connection String>";
            string containerName = "<Your Container Name>";
            string blobName = "<Your Blob Name>";
            string imagePath = "<Your Image Path>";

            BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);
            BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);
            BlobClient blobClient = containerClient.GetBlobClient(blobName);

            using (FileStream imageStream = new FileStream(imagePath, FileMode.Open))
            {
                blobClient.Upload(imageStream);
            }

            Console.WriteLine("Image uploaded successfully!");
        }
    }
}

The code is pretty simple. First, we create a BlobServiceClient instance using the connection string. Next, we get the BlobContainerClient instance for the specified container name. We then get the BlobClient instance for the specified blob name.

Finally, we open the image file as a FileStream and call the Upload method on the BlobClient instance to upload the image to Azure Blob Storage. We then print a message to the console indicating that the image has been uploaded successfully.

Conclusion

In this tutorial, we have learned how to upload images to Azure Blob Storage using the Azure Blob Storage C# SDK. With Azure Blob Storage, you can easily store and manage large amounts of image data in the cloud, and make it accessible to clients via HTTP or HTTPS.
