ReadAsync Method

DataTableReader.ReadAsync Method

.NET Framework 4.6 and 4.5

Implements the asynchronous version of Read, but returns a Task synchronously, blocking the calling thread.

This member is overloaded. For complete information about this member, including syntax, usage, and examples, click a name in the overload list.

  Name Description
Public method ReadAsync() An asynchronous version of Read, which advances the reader to the next record in a result set. This method invokes ReadAsync with CancellationToken.None. (Inherited from DbDataReader.)
Public method ReadAsync(CancellationToken) This is the asynchronous version of Read. Providers should override with an appropriate implementation. The cancellationToken may optionally be ignored.The default implementation invokes the synchronous Read method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by Read will be communicated via the returned Task Exception property.Do not invoke other methods and properties of the DbDataReader object until the returned Task is complete. (Inherited from DbDataReader.)
