CloudBlob.UploadFile Method (String, BlobRequestOptions)

Updated: April 24, 2013

[This topic is part of the Windows Azure Storage Client Library 1.7, which has been deprecated. The current recommended version is Storage Client Library 3.0.]

Uploads a file from the file system to a block blob, using a conditional request based on the BlobRequestOptions that you specify.

Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)
'Bruk

'Erklæring
Public Overridable Sub UploadFile ( _
	fileName As String, _
	options As BlobRequestOptions _
)

Parameters

fileName

Type: System.String

The path and file name of the file to upload.

options

Type: Microsoft.WindowsAzure.StorageClient.BlobRequestOptions

An object that specifies any additional options for the request.

The following code example uploads a file from the local computer to a blob, using the specified blob request options.

static void UploadBlobFromFile(Uri blobEndpoint, string accountName, string accountKey)
{
    // Create a service client for credentialed-access to the blob.
    CloudBlobClient blobClient = 
        new CloudBlobClient(blobEndpoint, 
            new StorageCredentialsAccountAndKey(accountName, accountKey));
 
    // Get a reference to a container, which may or may not already exist in the cloud.
    CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");
 
    // Create a new container in the cloud if one with this container address does not already exist.
    container.CreateIfNotExist();
 
    // Get a reference to a blob, which may or may not exist.
    CloudBlob blob = container.GetBlobReference("myfile.txt");
 
    // Create a BlobRequestOptions object.
    BlobRequestOptions options = new BlobRequestOptions();
 
    // Use the BlobRequestOptions object to set options for the request.
    // E.g., Specify a retry policy of 10 retries.
    options.RetryPolicy = 
        RetryPolicies.RetryExponential(10, RetryPolicies.DefaultClientBackoff);
 
    // Upload content to the blob, which will create the blob if it does not already exist.
    // If the operation fails, try it again - up to ten retries before giving up.
    blob.UploadFile("c:\\myfile.txt", options);
}

The maximum size for a block blob is 200 GB, and a block blob can include no more than 50,000 blocks.
