  3. Create an occasion of CreateCloudBlobClient.
  4. Gives a client-side logical illustration of the Home windows Azure Blob service. This consumer is used to configure and execute requests in opposition to the Blob service.
    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
  5. Get a container within the Home windows Azure Blob service. Create the container if it doesn’t exist.
  6. This must be in decrease case.
    CloudBlobContainer container = blobClient.GetContainerReference("blobcontainer");
  7. Will get a reference to a block blob within the container and uploads a string textual content to it.

Instance. Day by day Gross sales

Having gone into the fundamentals of Azure WebJobs, the next is an instance of the place all of the ideas can be utilized and utilized.


Think about a state of affairs the place a gross sales WebApp is being deployed into Azure. The App shops gross sales info from a number of branches of a retailer.

The requirement is each day at a selected time within the morning, compile the full gross sales per area, save the report on blob storage, and e-mail the report back to the administrators.

Assume the Database schema of the Utility is like the next.


Retrieving Day by day Gross sales from the Database

The code block beneath connects to an Azure Database and selects and aggregates the gross sales info as required.

public string GetDailySales(string date)

    string SalesDetails = "";

        string StrCommand = @"choose area, sum(quantity) AMOUNT

            smtp.Credentials = new NetworkCredential(emailFrom, password);
            smtp.EnableSsl = enableSSL;
            Console.WriteLine("E-mail despatched to " + emailTo + " at " + DateTime.Now);
    catch (Exception e)
        Console.WriteLine("E-mail failed" + e.Message);

Saving the end in Blob Storage

The perform beneath creates a container if it doesn’t exist and saves the end in a blob.

public static void WriteToBlob(string salesreport)
        string acs = "DefaultEndpointsProtocol=https;AccountName=xxx;AccountKey=xxx";

        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(acs);
        CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
        CloudBlobContainer container = blobClient.GetContainerReference("salesinfo");
        CloudBlockBlob blob = container.GetBlockBlobReference("DailyReport" + DateTime.Now + ".txt");

        Console.WriteLine("File saved efficiently"); ;

    catch (Exception e)
        Console.WriteLine("Saving to blob failed " + e.Message);
