This beginner-level course targets C# developers who want to develop their Microsoft Azure skills. It provides foundational knowledge of the key Microsoft Azure concepts needed for every developer and explains foundational services used in the AI, hosting, storage, and monitoring areas. 

After completing this course, you’ll be familiar with foundational Microsoft Azure concepts and will be able to build basic Microsoft Azure solutions.

Master Azure: Build Microsoft Azure Solution with C#

# Preparing the code

Now that we have set up the storage account, our next step is to update our existing code so that the API can upload files to this storage account. Here's how:

- In the `csproj` file, we will add the following NuGet package. 

This will allow us to use the Azure storage account SDK.

- Within the `ImageDescriberApi.cs` file, we will insert the function given below:

private static async Task UploadFileStreamToStorageAccount(Stream stream, string fileName)
        {
            // Connection string for the Azure storage account
        string connectionString = "{{storageAccountConnectionString}}";

        // Name of the blob container where the file will be uploaded
        string containerName = "images-backup";

        BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);

        BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);
        await containerClient.CreateIfNotExistsAsync();
        BlobClient blobClient = containerClient.GetBlobClient(fileName);

        await blobClient.UploadAsync(stream, true);
        }


- The function, named `UploadFileStreamToStorageAccount`, performs the following operations:

    - **Lines 4-9:** Create a `BlobServiceClient` using the provided connection string.

    - **Line 11:** Obtain a reference to a container client named `images-backup`.

      > **Note:** `images-backup` is a name we have selected, but you can choose a name that suits your project.

    - **Line 12:** Create the container if it doesn't exist.
    - **Line 13:** Retrieve a Blob client using the file name specified in the function parameter.
    - **Line 15:** Upload the stream sent in the function parameter.

- We will insert the following code to enable image uploading to the Azure Storage account. This operation will upload the image as a Blob and append a time stamp to its name. Remember to save the file after making these modifications.

Update the API code to support uploading images to the Storage Account.
