Ejemplos

// This is one common way of creating a CloudStorageAccount object. You can get 
// your Storage Account Name and Key from the Azure Portal.
StorageCredentials credentials = new StorageCredentials(accountName, accountKey);
CloudStorageAccount storageAccount = new CloudStorageAccount(credentials, useHttps: true);

// Another common way to create a CloudStorageAccount object is to use a connection string:
// CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);

CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// This call creates a local CloudBlobContainer object, but does not make a network call
// to the Azure Storage Service. The container on the service that this object represents may
// or may not exist at this point. If it does exist, the properties will not yet have been
// popluated on this object.
CloudBlobContainer blobContainer = blobClient.GetContainerReference(containerName);

// This makes an actual service call to the Azure Storage service. Unless this call fails,
// the container will have been created.
blobContainer.Create();

// This also does not make a service call, it only creates a local object.
CloudBlockBlob blob = blobContainer.GetBlockBlobReference(blobName);

// This transfers data in the file to the blob on the service.
blob.UploadFromFile(inputFileName);
