ReadUserFeedAsync(String, FeedOptions)

Reads the feed (sequence) of User for a database from the Azure Cosmos DB service as an asynchronous operation.

public System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.FeedResponse<Microsoft.Azure.Documents.User>> ReadUserFeedAsync (string usersLink, Microsoft.Azure.Documents.Client.FeedOptions options = default);

abstract member ReadUserFeedAsync : string * Microsoft.Azure.Documents.Client.FeedOptions -> System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.FeedResponse<Microsoft.Azure.Documents.User>>

Public Function ReadUserFeedAsync (usersLink As String, Optional options As FeedOptions = Nothing) As Task(Of FeedResponse(Of User))

Parameters

usersLink

String

The SelfLink of the resources to be read. E.g. /dbs/db_rid/users/

options

FeedOptions

(Optional) The request options for the request.

Returns

Task<FeedResponse<User>>

A System.Threading.Tasks containing a ResourceResponse<TResource> which wraps a User containing the read resource record.

Exceptions

ArgumentNullException

If usersLink is not set.

DocumentClientException

This exception can encapsulate many different types of errors. To determine the specific error always look at the StatusCode property. Some common codes you may get when creating a Document are:

StatusCode	Reason for exception
404	NotFound - This means the resource feed you tried to read did not exist. Check the parent rids are correct.
429	TooManyRequests - This means you have exceeded the number of request units per second. Consult the DocumentClientException.RetryAfter value to see how long you should wait before retrying this operation.

Examples

int count = 0;
string continuation = string.Empty;
do
{
    // Read the feed 10 items at a time until there are no more items to read
    FeedResponse<User> response = await client.ReadUserFeedAsync("/dbs/db_rid/users/",
                                                    new FeedOptions
                                                    {
                                                        MaxItemCount = 10,
                                                        RequestContinuation = continuation
                                                    });

    // Append the item count
    count += response.Count;

    // Get the continuation so that we know when to stop.
     continuation = response.ResponseContinuation;
} while (!string.IsNullOrEmpty(continuation));
