The specified container does not exist

Am stuck with this error The specified container does not exist.

let me explain,

CloudBlobClient blobStorage = GetBlobStorage("upload");
CloudBlockBlob blob = BlobPropertySetting(blobStorage, Guid.NewGuid().ToString().ToLower() + Path.GetExtension(file.FileName));
blob.UploadFromStream(file.InputStream);

public static CloudBlobClient GetBlobStorage(string cloudBlobContainserName)
    {
        CloudBlobClient blobStorage;
        try
        {
            var storageAccount = CloudStorageAccount.FromConfigurationSetting("StorageConnectionString");
            blobStorage = storageAccount.CreateCloudBlobClient();
            CloudBlobContainer container = blobStorage.GetContainerReference(cloudBlobContainserName); 
            container.CreateIfNotExist();
            var permissions = container.GetPermissions();
            permissions.PublicAccess = BlobContainerPublicAccessType.Container;
            container.SetPermissions(permissions);
        }
        catch (Exception ex)
        {
            Logger.LogError(Log4NetLogger.Category.Exception, "Error in : BlobHandler.GetBlobStorage :>> Exception message: " + ex.Message);
            throw;
        }
        return blobStorage;
    }
    public static CloudBlockBlob BlobPropertySetting(CloudBlobClient cloudBlobClientReferenceName, string blobContentName)
    {
        CloudBlockBlob blob = cloudBlobClientReferenceName.GetBlockBlobReference(blobContentName);


        return blob;
    }

and my StorageConnectionString is

      <Setting name="StorageConnectionString" value="DefaultEndpointsProtocol=https;AccountName=duw;AccountKey=bla bla" />

container 'upload' and the storage account 'duw' exist.

executing blob.UploadFromStream(file.InputStream); statement causes the error.

stack trace :

at Microsoft.WindowsAzure.StorageClient.Tasks.Task1.get_Result() at Microsoft.WindowsAzure.StorageClient.Tasks.Task1.ExecuteAndWait() at Microsoft.WindowsAzure.StorageClient.TaskImplHelper.ExecuteImpl(Func`1 impl) at Microsoft.WindowsAzure.StorageClient.CloudBlob.UploadFromStream(Stream source, BlobRequestOptions options) at Microsoft.WindowsAzure.StorageClient.CloudBlob.UploadFromStream(Stream source) at DAL.Handlers.BlobHandler.CreateAd(HttpPostedFileBase file, Advertisement model) in D:\DU Server\trunk\Du Server\DAL\Handlers\BlobHandler.cs:line 151

inner exception:

{"The remote server returned an error: (404) Not Found."}

can any body help me to sort this out.

Short version

Try the following code for BlobPropertySetting function:

 public static CloudBlockBlob BlobPropertySetting(CloudBlobClient cloudBlobClientReferenceName, string blobContentName)
    {
        CloudBlockBlob blob = cloudBlobClientReferenceName.GetBlockBlobReference("upload/" + blobContentName);
        return blob;
    }

Now for the longer version :)

The reason you're getting this error is because of the way you are constructing the CloudBlockBlob object in BlobPropertySetting method. When you use your code, it creates a blob object with the following URI: https://duv.blob.core.windows.net/blobContentName. If you notice, there's no container name there. Since there's no container name, storage client library assumes that you're trying to create a blob in $root blob container which is a special blob container. You can read more about it here: http://msdn.microsoft.com/en-us/library/windowsazure/hh488356.aspx. Since your storage account does not have this container, you get 404 - Resource Not Found error.

I am very late, but still thought if my answer would be useful for anyone.

I resolved this error by putting the correct "container name". It was different by default. I have cloned this GIT project : https://github.com/Azure-Samples/storage-blob-upload-from-webapp-node

const
      express = require('express')
    , router = express.Router()
    , azureStorage = require('azure-storage')
    , blobService = azureStorage.createBlobService()
    , containerName = 'container' // added container name here, as my container name
    , config = require('../config')
;
