| CloudBlobDirectory.ListBlobsSegmented Method (Int32, ResultContinuation, BlobRequestOptions) |
| See Also |
|
|
Returns a result segment containing a collection of blob items. Use this overload when you want to control the maximum number of results returned at a time, and when you want to use a continuation token to determine whether there are more results to return from the service after the current page completes. Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)

Dim instance As CloudBlobDirectory Dim maxResults As Integer Dim continuationToken As ResultContinuation Dim options As BlobRequestOptions Dim returnValue As ResultSegment(Of IListBlobItem) returnValue = instance.ListBlobsSegmented(maxResults, continuationToken, options) |

Parameters
- maxResults
A non-negative integer value that indicates the maximum number of results to be returned at a time, up to the per-operation limit of 5000. If this value is zero, the maximum possible number of results will be returned, up to 5000.
- continuationToken
A continuation token returned by a previous listing operation.
- options
An object that specifies any additional options for the request.
Return Value
A result segment containing objects that implement IListBlobItem.Remarks
The ListBlobsSegmented method begins an operation to list blobs in pages. To specify the page size to return, pass in a non-zero value for the maxResults parameter. Passing in zero for the maxResults parameter returns either the maximum number of results available, or the per-operation limit of 5000 results.
If you have specified a page size, you can check the HasMoreResults property to check whether the page is complete. For example, if you have specified a page size of 10,000, a value which exceeds the per-operation limit, HasMoreResults will return true, indicating that the page is not complete. Note that if you have not specified a page size, HasMoreResults will always be false.
If you have not specified a page size, or the value of maxResults is zero, then check the value of the ContinuationToken property to determine whether there are more results to return. The continuation token is non-null as long as there are more results to return from the service.
Call the GetNext method to return the next segment of results from the service.
The types of objects returned by the ListBlobsSegmented method depend on the type of listing that is being performed. If the UseFlatBlobListing property is set to true, the listing will return an enumerable collection of CloudBlob objects. If UseFlatBlobListing is set to false (the default value), the listing may return a collection containing CloudBlob objects and CloudBlobDirectory objects. The latter case provides a convenience for subsequent enumerations over a virtual blob hierarchy.
