DataServiceQuery.BeginExecute Method

Asynchronously sends a request to execute the data service query.

Namespace:  System.Data.Services.Client
Assembly:  System.Data.Services.Client (in System.Data.Services.Client.dll)

public IAsyncResult BeginExecute(
	AsyncCallback callback,
	Object state
)

Parameters

callback
Type: System.AsyncCallback
Delegate to invoke when results are available for client consumption.
state
Type: System.Object
User-defined state object passed to the callback.

Return Value

Type: System.IAsyncResult
An IAsyncResult object that is used to track the status of the asynchronous operation.

The returned IAsyncResult object is used to determine when the asynchronous operation has completed. For more information, see Asynchronous Operations (WCF Data Services).

The BeginExecute method uses the same semantics as the Execute method, however BeginExecute asynchronously sends the request so that the call does not block processing while waiting for the results from the service. According to the standard begin-end asynchronous pattern, the provided callback is invoked when query results are retrieved.
