Asynchronously enumerates the query. When using Entity Framework, this causes the results of the query to be loaded into the associated context. This is equivalent to calling ToList and then throwing away the list (without the overhead of actually creating the list).
public static System.Threading.Tasks.Task LoadAsync<TSource> (this System.Linq.IQueryable<TSource> source, System.Threading.CancellationToken cancellationToken = default);static member LoadAsync : System.Linq.IQueryable<'Source> * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Extension()>
Public Function LoadAsync(Of TSource) (source As IQueryable(Of TSource), Optional cancellationToken As CancellationToken = Nothing) As TaskType Parameters
- TSource
Parameters
- source
- IQueryable<TSource>
The source query.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A task that represents the asynchronous operation.
Exceptions
source is null.
If the CancellationToken is canceled.
Remarks
Multiple active operations on the same context instance are not supported. Use await to ensure that any asynchronous operations have completed before calling another method on this context. See Avoiding DbContext threading issues for more information and examples.
