CloudBlobClient.EndListBlobsWithPrefixSegmented Method

Updated: April 24, 2011

[This topic is part of the Microsoft Azure Storage Client Library 1.7, which has been deprecated. See Storage Client Library for the latest version.]

Ends an asynchronous operation to return a result segment containing a collection of blob items whose names begin with the specified prefix.

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

'Uso
Dim instance As CloudBlobClient
Dim asyncResult As IAsyncResult
Dim returnValue As ResultSegment(Of IListBlobItem)

returnValue = instance.EndListBlobsWithPrefixSegmented(asyncResult)

public ResultSegment<IListBlobItem> EndListBlobsWithPrefixSegmented (
	IAsyncResult asyncResult
)

Parameters

asyncResult

Type: System.IAsyncResult

An IAsyncResult that references the pending asynchronous operation.

Return Value

Type: Microsoft.WindowsAzure.StorageClient.ResultSegment

A result segment containing objects that implement IListBlobItem.

The following sample code lists blobs in a container with an asynchronous operation. The blob prefix includes the name of the container and the beginning of the blob name.

static void ListBlobsInSegmentsAsynchronously(Uri blobEndpoint, string accountName, string accountKey)
{
    //Create service client for credentialed access to the Blob service.
    CloudBlobClient blobClient = 
        new CloudBlobClient(blobEndpoint, new StorageCredentialsAccountAndKey(accountName, accountKey));

    //Begin the operation to return a page of up to 5000 blobs, passing the service client to the callback.
    blobClient.BeginListBlobsWithPrefixSegmented("lotsofblobs/0", ListBlobsInSegmentsCallback, blobClient);
}

static void ListBlobsInSegmentsCallback(IAsyncResult result)
{
    CloudBlobClient blobClient = (CloudBlobClient)result.AsyncState;

    //End the operation.
    ResultSegment<IListBlobItem> resultSegment = blobClient.EndListBlobsWithPrefixSegmented(result);

    //Enumerate the blob items.
    foreach (var blobItem in resultSegment.Results)
    {
        Console.WriteLine(blobItem.Uri);
    }

    //Check the continuation token to determine whether there are more results.
    if (resultSegment.ContinuationToken != null)
    {
        //Get the next result segment.
        resultSegment = resultSegment.GetNext();

        //Enumerate the blob items.
        foreach (var blobItem in resultSegment.Results)
        {
            Console.WriteLine(blobItem.Uri);
        }
    }
}

This method blocks until the listing operation is complete.
