DataServiceContext.EndExecute(Of TElement) Method (IAsyncResult)
Called to complete the BeginExecute.
Assembly: Microsoft.Data.Services.Client (in Microsoft.Data.Services.Client.dll)
'Declaration Public Function EndExecute(Of TElement) ( _ asyncResult As IAsyncResult _ ) As IEnumerable(Of TElement) 'Usage Dim instance As DataServiceContext Dim asyncResult As IAsyncResult Dim returnValue As IEnumerable(Of TElement) returnValue = instance.EndExecute(asyncResult)
The type returned by the query.
Return ValueType: System.Collections.Generic.IEnumerable(Of )
The results returned by the query operation.
When asyncResult is Nothing.
When asyncResult did not originate from this DataServiceContext instance.
When the EndExecute method was previously called.
When an error is raised either during execution of the request or when it converts the contents of the response message into objects.
When the data service returns an HTTP 404: Resource Not Found error.
According to the standard begin-end asynchronous pattern, the provided callback is invoked when query results are retrieved. For more information, see Asynchronous Operations (WCF Data Services).
When the callback is invoked, all results have been read from the HTTP stream, but they have not been processed; no local user-facing objects have been materialized or modified and identity resolution has not occurred. When EndExecute is invoked, a DataServiceResponse is created and returned but the results still have not been processed. Identity resolution, object materialization, and manipulation occur only when the user enumerates the results.
