Go to Windows azure storage and create the honggensave account. The result is shown in.

The main code is as follows.

using Microsoft.WindowsAzure;using Microsoft.WindowsAzure.ServiceRuntime;using Microsoft.WindowsAzure.StorageClient;  private static bool storageInitialized = false;        private static object gate = new Object();        private static CloudBlobClient blobStorage;        private static CloudQueueClient queueStorage;        protected void Page_Load(object sender, EventArgs e)        {            if (!Page.IsPostBack)            {                Timer1.Enabled = true;            }        }        protected void SignButton_Click(object sender, EventArgs e)        {            if (FileUpload1.HasFile)            {                InitializeStorage();                                // upload the image to blob storage                CloudBlobContainer container = blobStorage.GetContainerReference("guestbookpics");                string uniqueBlobName = string.Format("image_{0}.jpg", Guid.NewGuid().ToString());                CloudBlockBlob blob = container.GetBlockBlobReference(uniqueBlobName);                blob.Properties.ContentType = FileUpload1.PostedFile.ContentType;                blob.UploadFromStream(FileUpload1.FileContent);                System.Diagnostics.Trace.TraceInformation("Uploaded image '{0}' to blob storage as '{1}'", FileUpload1.FileName, uniqueBlobName);                // create a new entry in table storage                GuestBookEntry entry = new GuestBookEntry() { GuestName = NameTextBox.Text, Message = MessageTextBox.Text, PhotoUrl = blob.Uri.ToString(), ThumbnailUrl = blob.Uri.ToString() };                GuestBookEntryDataSource ds = new GuestBookEntryDataSource();                ds.AddGuestBookEntry(entry);                System.Diagnostics.Trace.TraceInformation("Added entry {0}-{1} in table storage for guest '{2}'", entry.PartitionKey, entry.RowKey, entry.GuestName);                // queue a message to process the image                var queue = queueStorage.GetQueueReference("guestthumbs");                var message = new CloudQueueMessage(String.Format("{0},{1},{2}", uniqueBlobName, entry.PartitionKey, entry.RowKey));                queue.AddMessage(message);                System.Diagnostics.Trace.TraceInformation("Queued message to process blob '{0}'", uniqueBlobName);            }            NameTextBox.Text = "";            MessageTextBox.Text = "";            DataList1.DataBind();        }        protected void Timer1_Tick(object sender, EventArgs e)        {            DataList1.DataBind();        }        private void InitializeStorage()        {            if (storageInitialized)            {                return;            }            lock (gate)            {                if (storageInitialized)                {                    return;                }                try                {                    // read account configuration settings                    var storageAccount = CloudStorageAccount.FromConfigurationSetting("DataConnectionString");                    // create blob container for images                    blobStorage = storageAccount.CreateCloudBlobClient();                    CloudBlobContainer container = blobStorage.GetContainerReference("guestbookpics");                    container.CreateIfNotExist();                    // configure container for public access                    var permissions = container.GetPermissions();                    permissions.PublicAccess = BlobContainerPublicAccessType.Container;                    container.SetPermissions(permissions);                    // create queue to communicate with worker role                    queueStorage = storageAccount.CreateCloudQueueClient();                    CloudQueue queue = queueStorage.GetQueueReference("guestthumbs");                    queue.CreateIfNotExist();                }                catch (WebException)                {                    throw new WebException("Storage services initialization failure.

If running locally, "                        + "ensure that the Development Storage service is running.");                }                storageInitialized = true;            }        }

Use azure storage explorer to View cloud storage conditions, such:

Note that the configuration file is used for local debugging:

<Setting name = "dataconnectionstring" value = "usedevelopmentstorage = true"/>
<Setting name = "Microsoft. windowsazure. plugins. Diagnostics. connectionstring" value = "usedevelopmentstorage = true"/>

Use the correct accountname and accountkey when deploying to azure. Set primary access key here.

<Setting name = "dataconnectionstring" value = "defaultendpointsprotocol = HTTPS; accountname = honggensave; accountkey = assets/9i + lw + vs5fwpgk/4jw + Signature ="/>
<Setting name = "Microsoft. windowsazure. plugins. diagnostics. connectionstring "value =" defaultendpointsprotocol = HTTPS; accountname = honggensave; accountkey = Hangzhou/9i + lw + vs5fwpgk/4jw + edfzfsitypwoyffbnxxxx "/>
 

View table data storage. You can see partitionkey and rowkey.

Store a jpg image, which can be accessed using the following URL:
