How to

Connect to Blob Storage

• Using connection string
  

To connect to Azure Blob Storage, instantiate the BlobServiceClient class by passing your connection string to the constructor

    string connectionString = "YourAzureStorageConnectionString";

    BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);

In addition to using the connection string, Azure provides two other ways to connect to Blob Storage:

• Using Account Key:
  

Account Key is one of the simplest ways to authenticate to your Azure Storage. You use the account name and account key to create a StorageSharedKeyCredential object and then connect to the Blob service.

    string accountName = "YourStorageAccountName";

    string accountKey = "YourStorageAccountKey";

    StorageSharedKeyCredential sharedKeyCredential = new StorageSharedKeyCredential(accountName, accountKey);

    BlobServiceClient blobServiceClient = new BlobServiceClient(new Uri($"https://{accountName}.blob.core.windows.net"),

    sharedKeyCredential);

• Using SAS Token: SAS Token (Shared Access Signature) allows granular access control to Azure Storage resources without exposing your account keys. It generates a time-bound, permission-limited token to access blobs, containers, etc.
  
  string sasToken = "YourSasToken"; // e.g. ?sv=2020-08-04&ss=bfqt&srt=sco&sp=rwdlacupx&se=2024-10-05T18:56:09Z&st=2024-10-04T10:56:09Z&spr=https&sig=YourGeneratedSAS";string blobServiceEndpoint = "https://YourStorageAccountName.blob.core.windows.net";
  
  BlobServiceClient blobServiceClient = new BlobServiceClient(new Uri($"{blobServiceEndpoint}{sasToken}"));
  
  

There are two ways to generate SAS token:

1. From portal:
   
2. From Microsoft Azure Storage Explorer:
   

Upload and Download

The Azure SDK provides multiple methods for uploading and downloading documents.

//Upload:

await blobClient.UploadAsync(stream, overwrite);

//Download:

await blobClient.DownloadContentAsync();
