File Uploading to Azure Storage by ASP.NET Webpages

Question

There are some reference about File Uploading to Azure BY ASP.NET MVC but I can't find none in field of ASP.NET Webpages

How to implement such code to upload to Azure Storage?

Well.. For more information,

My goal is image uploading in CK Editor

but Due to Azure Hosting, ordinary CKEditor reference is not working.

So I googled and use this code block

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("StorageConnectionString"));

// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference("lawimage");

// Retrieve reference to a blob named "myblob".
CloudBlockBlob blockBlob = container.GetBlockBlobReference("myblob");

// Create or overwrite the "myblob" blob with contents from a local file.
using (var fileStream = System.IO.File.OpenRead(name))
{
    blockBlob.UploadFromStream(fileStream);
}

But it doesn't work,

and my 'web.config' is

<appSettings>
    <add key="StorageConnectionString" value="DefaultEndpointsProtocol=https;AccountName=lawcbt;AccountKey=[MyAccountKey]/>
</appSettings>

Is anyone ever did upload to Azure Storage via ASP.NET WebPages?

P.S> To be more clear, My 'upload.aspx' source file is this

upload.aspx

Are you getting some kind of processing error? Or does the POST request to the server return OK (200) but the file is not on the container? — Matias Quaranta, Mar 02 '16 at 14:45

Sure, you have to upload the file first to you Asp.Net webpage. From there you can upload it to your blobstorage. In your code it seems you are trying to upload a file from the server to blobstorage. First you have to upload the file to server, and then you can send the stream to the blobstorage.

I have solved myself! By using Visual Studio, I found a bugging point. olleh!!

Even though I don't like Visual Studio, Visual Studio is very powerful tool Tongue Out

Maybe It's heavyness is worth for that.

This code will work!

<%@ Import namespace="System.Configuration" %>
<%@ Import namespace="Microsoft.WindowsAzure" %>
<%@ Import namespace="Microsoft.WindowsAzure.Storage" %>
<%@ Import namespace="Microsoft.WindowsAzure.Storage.Auth" %>
<%@ Import namespace="Microsoft.WindowsAzure.Storage.Blob" %>

......

    HttpPostedFile theFile = HttpContext.Current.Request.Files[0];
    // Azure Upload 

    // Retrieve storage account from connection string.
    StorageCredentials sc = new StorageCredentials("[MyStorageName]", "[MyKey]");
    CloudStorageAccount storageAccount = new CloudStorageAccount(sc, false);

    // Create the blob client.
    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

    // Retrieve reference to a previously created container.
    CloudBlobContainer container = blobClient.GetContainerReference("lawimage");

    // Retrieve reference to a blob named "myblob".
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(sFileName);

    // Create or overwrite the "myblob" blob with contents from a local file.
    using (var fileStream = theFile.InputStream)
    {
        blockBlob.UploadFromStream(fileStream);
    }
