How to download Blobs from Windows Azure

In this Post i would like tto explain about Downloading of Blobs using C# Code.

There are so many ways to download the Blob, am going to Explain Using Shared access signature(SAS).

//Using Azure Storage

// Retrieve storage account from connection string.           

 CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);

                    // Create the blob client.

                    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

                    string containerName = (sender as LinkButton).CommandArgument;

                    string fileName = (sender as LinkButton).Text;

                    //getContainer Name

                    CloudBlobContainer container = blobClient.GetContainerReference("myContainer");

                    CloudBlockBlob blockBlob = container.GetBlockBlobReference(fileName);

                    if (blockBlob.Exists())

                    {

                        //set the cache control

                        Response.Cache.SetCacheability(HttpCacheability.Public);

                        Response.Cache.SetValidUntilExpires(true);

                        Response.Cache.SetMaxAge(TimeSpan.FromSeconds(300));

                        Response.Expires = 300;

                       

                        //set the output content type

                        Response.ContentType = blockBlob.Properties.ContentType;

                        Response.AppendHeader("Content-Disposition", "attachment; filename="+fileName);

                        //download the asset to the output stream

                        blockBlob.DownloadToStream(Response.OutputStream);

                    }
