ReadConflictAsync(String, RequestOptions)
Reads a Conflict from the Azure Cosmos DB service as an asynchronous operation.
public System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.ResourceResponse<Microsoft.Azure.Documents.Conflict>> ReadConflictAsync (string conflictLink, Microsoft.Azure.Documents.Client.RequestOptions options = default);abstract member ReadConflictAsync : string * Microsoft.Azure.Documents.Client.RequestOptions -> System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.ResourceResponse<Microsoft.Azure.Documents.Conflict>>
override this.ReadConflictAsync : string * Microsoft.Azure.Documents.Client.RequestOptions -> System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.ResourceResponse<Microsoft.Azure.Documents.Conflict>>Public Function ReadConflictAsync (conflictLink As String, Optional options As RequestOptions = Nothing) As Task(Of ResourceResponse(Of Conflict))Parameters
- conflictLink
- String
The link to the Conflict to be read.
- options
- RequestOptions
(Optional) The request options for the request.
Returns
A System.Threading.Tasks containing a ResourceResponse<TResource> which wraps a Conflict containing the read resource record.
Implements
Exceptions
If conflictLink 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 you tried to read did not exist. |
| 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
//Reads a Conflict resource from a Database
// - sample_database is the ID of the database
// - sample_collection is the ID of the collection
// - conflict_id is the ID of the conflict to be read
var conflictLink = "/dbs/sample_database/colls/sample_collection/conflicts/conflict_id";
Conflict conflict = await client.ReadConflictAsync(conflictLink);
Remarks
Doing a read of a resource is the most efficient way to get a resource from the Database. If you know the resource's ID, do a read instead of a query by ID.
The example shown uses ID-based links, where the link is composed of the ID properties used when the resources were created. You can still use the SelfLink property of the Conflict if you prefer. A self-link is a URI for a resource that is made up of Resource Identifiers (or the _rid properties). ID-based links and SelfLink will both work. The format for conflictLink is always "/dbs/{db identifier}/colls/{collectioon identifier}/conflicts/{conflict identifier}" only the values within the {...} change depending on which method you wish to use to address the resource.

- conflictUri
- Uri

Examples
//Reads a Conflict resource where
// - db_id is the ID property of the Database
// - coll_id is the ID property of the DocumentCollection
// - conflict_id is the ID property of the Conflict you wish to read.
var conflictLink = UriFactory.CreateConflictUri("db_id", "coll_id", "conflict_id");
Conflict conflict = await client.ReadConflictAsync(conflictLink);
