Returns a result segment containing a collection of table names in the storage account. 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)
Usage
| Visual Basic |
|---|
Dim instance As CloudTableClient Dim maxResults As Integer Dim continuationToken As ResultContinuation Dim returnValue As ResultSegment(Of String) returnValue = instance.ListTablesSegmented(maxResults, continuationToken) |

Parameters
- maxResults
Type: System.Int32
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 1000. If this value is zero, the maximum possible number of results will be returned, up to 1000.
- continuationToken
Type: Microsoft.WindowsAzure.StorageClient.ResultContinuation
A continuation token returned by a previous listing operation.
Return Value
Type: Microsoft.WindowsAzure.StorageClient.ResultSegment A result segment containing table names.Example
The following code example lists table names in pages of five. The continuation token will be non-null until the listing is complete.

// Create service client for credentialed access to the Table service.
CloudTableClient tableClient = new CloudTableClient(storageAccount.TableEndpoint.ToString(),

//Return a result segment of table names.
ResultSegment<String> resultSegment = tableClient.ListTablesSegmented(5, null);
//Print table names to the console.
WriteTableNames(resultSegment);
//Check HasMoreResults to determine whether the page is complete.
if (resultSegment.HasMoreResults)
{
resultSegment.GetNext();
//Print table names to the console.
WriteTableNames(resultSegment);
}
//After the page is complete, check the continuation token to determine whether there are more
//results on the server.
while (resultSegment.ContinuationToken != null)
{
resultSegment = resultSegment.GetNext();
//Print table names to the console.
WriteTableNames(resultSegment);

public static void WriteTableNames(ResultSegment<string> resultSegment)
{
foreach (string tableName in resultSegment.Results)
{
Console.WriteLine(tableName);
}

Remarks
The ListTablesSegmented method lists table names in pages. A page is set of results of a specified size; it is represented by the ResultSegment class.
By returning table names in pages, you can control the number of table names returned per operation. This may be useful if, for example, you are displaying a web page with some predefined number of table names on it.
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 1000 results.
If you have specified a page size, you can check the HasMoreResults property to check whether the page is complete. If HasMoreResults is true, the complete page has not been returned for some reason. Call GetNext to return the remaining results in the page.
Note that if you have not specified a page size, HasMoreResults will always be false. Check the value of the ContinuationToken property to determine whether there are more results to return from the service after the page is complete. The continuation token is non-null as long as there are more results to return from the service. If the page is complete, then HasMoreResults will be false, but if the continuation token is non-null, there are additional results to return beyond that page.
Call the GetNext method to return the next segment of results from the service.
