public System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.FeedResponse<Microsoft.Azure.Documents.Permission>> ReadPermissionFeedAsync (string permissionsLink, Microsoft.Azure.Documents.Client.FeedOptions options = default);abstract member ReadPermissionFeedAsync : string * Microsoft.Azure.Documents.Client.FeedOptions -> System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.FeedResponse<Microsoft.Azure.Documents.Permission>>Public Function ReadPermissionFeedAsync (permissionsLink As String, Optional options As FeedOptions = Nothing) As Task(Of FeedResponse(Of Permission))Parameters
- permissionsLink
- String
The SelfLink of the resources to be read. E.g. /dbs/db_rid/users/user_rid/permissions/
- options
- FeedOptions
(Optional) The request options for the request.
Returns
A System.Threading.Tasks containing a ResourceResponse<TResource> which wraps a Permission containing the read resource record.
Exceptions
If permissionsLink is not set.
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<Permission> response = await client.ReadPermissionFeedAsync("/dbs/db_rid/users/user_rid/permissions/",
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));
